Answer:
-3x+10y
Step-by-step explanation:
Given the expression [tex]-4\left(2x-y\right)+y+5\left(x+y\right)[/tex], we are to simplify by combining the like terms. On simplification we have;
[tex]= -4\left(2x-y\right)+y+5\left(x+y\right)[/tex]
Open the parenthesis:
[tex]= -4(2x)-4(-y)+y+5(x)+5(y)\\\\= -8x+4y+y+5x+5y[/tex]
Collect the like terms:
[tex]= -8x+5x+4y+y+5y[/tex]
Sum up the resulting expression
[tex]= -8x+5x+4y+y+5y\\= -3x+10y[/tex]
Hence the required expression on simplification is -3x+10y
Johnny’s vegetable garden is rectangular. The length of the garden is 2x-1 and the width of the garden is 3x+2. Find the Perimeter and Area of the garden.
Answer:
[tex] \boxed{\sf Perimeter \: of \: rectangular \: garden = 10x + 2} [/tex]
[tex] \boxed{\sf Area \: of \: rectangular \: garden = 6x^2 + x - 2} [/tex]
Given:
Length of rectangular garden = 2x - 1
Width of rectangular garden = 3x + 2
Step-by-step explanation:
[tex] \sf Perimeter \: of \: rectangular \: garden = 2(Length + Width)[/tex]
[tex] \sf = 2((2x - 1) + (3x + 2))[/tex]
Grouping like terms:
[tex] \sf = 2((2x + 3x) + (2 - 1))[/tex]
2x + 3x = 5x:
[tex] \sf = 2(5x + (2 - 1))[/tex]
2 - 1 = 1:
[tex] \sf = 2(5x + 1)[/tex]
[tex] \sf = (2 \times 5x) + (2 \times 1)[/tex]
2 × 5x = 10x:
[tex] \sf = 10x + (2 \times 1)[/tex]
2 × 1 = 2:
[tex] \sf = 10x + 2[/tex]
[tex] \therefore[/tex]
Perimeter of rectangular garden = 10x + 2
[tex] \sf Area \: of \: rectangular \: garden = Length \times Width[/tex]
[tex] \sf = (2x - 1)(3x + 2)[/tex]
[tex] \sf = 2x(3x + 2) - 1(3x + 2)[/tex]
[tex] \sf = (2x \times 3x) + (2x \times 2) - (1 + 3x) - (1 \times 2)[/tex]
2x × 3x = 6x²:
[tex] \sf = 6 {x}^{2} + (2x \times 2) - (1 + 3x) - (1 \times 2)[/tex]
2x × 2 = 4x:
[tex] \sf = 6 {x}^{2} + 4x - (1 + 3x) - (1 \times 2)[/tex]
1 × 3x = 3x:
[tex] \sf = 6 {x}^{2} + 4x - 3x - (1 \times 2)[/tex]
1 × 2 = 2:
[tex] \sf = 6 {x}^{2} + (4x - 3x) - 2[/tex]
4x - 3x = x:
[tex] \sf = 6 {x}^{2} + x - 2[/tex]
[tex] \therefore[/tex]
Area of rectangular garden = 6x² + x - 2
Answer:
Perimeter = 10x+2 m
Area = 6x²+x-2 m²
Step-by-step explanation:
Length of garden (l) = 2x-1
width or breadth of garden ( b) = 3x+2
Now,
Perimeter of the garden (p) = 2( l + b)
= 2 ( 2x-1 + 3x+2 )
= 2 ( 5x + 1 )
= 10x+2 m. ( Answer )
Again,
Area of garden (a) = l * b
= ( 2x-1 ) ( 3x+2 )
= 2x ( 3x+2 ) -1 ( 3x+2 )
= 6x² + 4x - 3x - 2
= 6x²+x-2 m². ( Answer )

Answer: Hi!
A number that is bigger than 5 2/3 but smaller than 6 could be 5.7.
A number that is bigger than 5.6 but smaller than 5 2/3 could be 5.62.
Hope this helps!
In fact 5 2/3 means 5+2/3 for this. So,5+2/3 = 17/3 = 5.6
For first question, if "numbers" are also include rational numbers, you can write any rational number according to this interval. For example, 5.7 , 5.75, 5.9
But the second one, the interval that is shown us has the same value 5.6 and 5.6. So you cannot find a number which should bigger 5.6 and smaller 5.6 . It seems impossible I mean.
Find the missing value to the nearest hundredth.
Answer:
Option (A)
Step-by-step explanation:
Let the Sine of the given angle θ is,
Sinθ = [tex]\frac{x}{y}[/tex]
Then θ = [tex]\text{Sin}^{-1}(\frac{x}{y} )[/tex]
From the given values in the question,
Sinθ = [tex]\frac{7}{29}[/tex]
θ = [tex]\text{Sin}^{-1}(\frac{7}{29} )[/tex]
θ = 13.97°
Therefore, measure of the angle 'θ' will be 13.97°.
Option (A) will be the answer.
Determine the quadrant(s) in which (x, y) could be located. (Select all that apply.)
x > 0 and y < 0
Quadrant I
Quadrant II
Quadrant III
Quadrant IV
none of these
Answer:
D. Quadrant IV
Step-by-step explanation:
Directed numbers are numbers with either a positive sign or a negative sign. These numbers can be located easily on the number line. Examples are: 2, 5, -1, -3, -7, 9 etc.
Given that: x > 0 and y < 0
For example, let us consider specific directed number for x and y. Let x = 5 and y = -2, so that; (5, -2). This point can be located in the fourth quadrant of a Cartesian plane.
Therefore considering a Cartesian plane, the quadrant in which (x, y) could be located is: Quadrant IV.

Answer:
x = 30
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , thus
x + 4x + 30 = 180
5x + 30 = 180 ( subtract 30 from both sides )
5x = 150 ( divide both sides by 5 )
x = 30

Three times the sum of half a number and 7 is 36
Answer:
your answer is 19.34
Step-by-step explanation:
let the number be x
half a number = ½ x
three times means multiplied by three
so,
3( ½ x) + 7 = 36
3( ½ x) = 36 - 7
3( ½ x) = 29
½ x = 29/3
½ x = 9.67...
x = 9.67 × 2 (when we moved ½ on the other side of the equal sign it › turns into 2/1 )
x = 19.34

Suppose you have a pocketful of change. You have some pennies (p) and some quarters (q). One expression could be used to describe the total number of coins in your pocket: p + q. A second expression could be used to describe the amount of money (in dollars) in your pocket: 0.01p + 0.25q. Notice that each expression describes a different characteristic of the change in your pocket. Evaluate each expression for the situation where you have 6 quarters and 7 pennies in your pocket. Type the correct answer in each box. Use numerals instead of words. For the amount of money, do not enter a dollar symbol.
Answer:
13
1.57
Step-by-step explanation:
So we have two equations regarding the number of quarters q and the number of pennies p:
[tex]p+q[/tex]
Which represents the total amount of coins and
[tex]0.01p+0.25q[/tex]
Which represents the total amount of money in dollars.
So we are asked to evaluation each expression for the situation in which we have 6 quarters and 7 pennies. Thus, plug 6 in for q and 7 in for p:
[tex]p+q\\(7)+(6)=13[/tex]
This tells us that we have 16 coins in total.
[tex]0.01(7)+0.25(6)\\=0.07+1.50\\=1.57[/tex]
This tells us that we have a total amount of $1.57.
Answer:
[tex]\Large \boxed {13} \\ \boxed{ 1.57}[/tex]
Step-by-step explanation:
Pennies ⇒ [tex]p[/tex]
Quarters ⇒ [tex]q[/tex]
First expression describes the total number of coins in the pocket ⇒ [tex]p+q[/tex]
Second expression describes the amount of money in dollars in the pocket ⇒ [tex]0.01p+0.25q[/tex]
There are 6 quarters and 7 pennies in the pocket.
First expression :
[tex]p+q \\ 7 + 6 = 13[/tex]
Second expression :
[tex]0.01p+0.25q \\ 0.01(7)+0.25(6) \\ 0.07+1.5 =1.57[/tex]

Given: DC =6x, and DA =4x+18 EB =4y-12, and ED =y+17 Y Find y. Then find ED, DB and EB.
Given:
(1) DC = 6x, and DA = 4x + 18, find the value of x. Then find AD, DC, and AC
(2) EB = 4y - 12, and ED = y + 17. Find y. Then find ED, DB and EB.
Answer:
x = 9, AD = 54, DC = 54, AC = 108
y = 23, ED = 40, DB = 40, EB = 80
Step-by-step explanation:The diagram for this question has been attached to this response.
(1) From the diagram, it can be observed that;
(a) DC and DA have equal lengths. i.e
=> DC = DA ---------------------(i)
(b) AC = DA + DC --------------------(ii)
But;
DC = 6x
DA = 4x + 18
Substitute the values of DC and DA into equation (i) as follows;
6x = 4x + 18 [Solve for x]
6x - 4x = 18
2x = 18
x = 9
Since x = 9, then
DC = 6x = 6(9) = 54
DA = 4x + 18 = 4(9) + 18 = 54
Therefore
DC = 54
AD = DA = 54
AC = 54 + 54 = 108 [using equation (ii)]
(2) Also, from the diagram, it can be observed that;
(a) ED and DB have equal lengths. i.e
=> ED = DB ---------------------(iii)
(b) EB = ED + DB --------------------(iv)
=>EB = ED + ED [since ED = DB]
=>EB = 2ED ------------------(v)
But;
EB = 4y - 12
ED = y + 17
Substitute the values of EB and ED into equation (v) as follows;
4y - 12 = 2(y + 17) [Solve for y]
4y - 12 = 2y + 34
4y - 2y = 34 + 12
2y = 46
y = 46 / 2
y = 23
Since y = 23, then
EB = 4y - 12 = 4(23) - 12 = 80
ED = y + 17 = 23 + 17 = 40
Therefore
EB = 80
ED = DB = 40
Answer:
x = 9, AD = 54, DC = 54, AC = 108
y = 23, ED = 40, DB = 40, EB = 80

S is in between T and U. ST = x + 4 and SU = 2x. TU = 16. Find the value of x.
Variable y varies directly with variable x. If x = 12, then y = 3. What is the value of y
when x = 8?
Answer:
y = 2Step-by-step explanation:
To find the value of y when x = 8 we must first find the relationship between the two variables.
The statement
y varies directly with variable x is written as
y = kx
where k is the constant of proportionality
when
x = 12
y = 3
Substitute the values into the above formula and solve for k
That's
3 = 12k
Divide both sides by 12
[tex]k = \frac{1}{4} [/tex]
So the formula for the variation is
[tex]y = \frac{1}{4} x[/tex]
when
x = 8
[tex]y = \frac{1}{4} \times 8[/tex]
we have the final answer as
y = 2Hope this helps you
Item 15 Question 1 Write and solve an equation to answer the question. The perimeter of the Norwegian flag is 190 inches. What are the dimensions of the flag? Equation: =190 y= Question 2 Label the dimensions of the flag in inches.
Answer:
40 inches by 55 inches.Step-by-step explanation:
The question lacks the required diagram. Find the diagram in the attachment.
The flag is rectangular in nature and the formula for calculating the perimeter of a rectangle is P = 2(L+W) where;
L is the length of the flag
W is the width of the flag
From the diagram, L = y and W = 11y/8
Since the perimeter = 190 inches, we will substitute the given parameters into the formula and firs calculate the value of y.
190 = 2(y+11y/8)
190 = 2y + 11y/4
multiply through by 4
760 = 8y+11y
760 = 19y
y = 760/19
y = 40
The length of the flag is 40 inches and the Width of the flag is 11(40)/8 = 55inches.
Hence, the dimensions of the flag in inches is 40 inches by 55 inches.
