7x+6= 5(x+2)
help me
Answers
Answer:
X = -2
Step-by-step explanation:
7x+6=5(X+2)
open the bracket
7x+6=5x+2
7x-5x=2-6
2x=-4
divide both sides by 2
X = -2
[tex] \huge \pink{solution}[/tex]
Given :7x+6=5(x+2)
Now We will use the distributive property to multiply 5 by x+2.
→7x+6=5x+10
We will Subtract 5x from both sides.
→7x+6−5x=10
We will Combine 7x and −5x to get 2x.
→2x+6=10
We will Subtract 6 from both sides.
2x=10−6
We will Subtract 6 from 10 to get 4.
2x=4
We will Divide both sides by 2.
x= 4/2
At last,We Divide 4 by 2 to get 2.
x=2

A small aircraft flies a 2160-mi round trip in a 45 mi/h wind. Find the average rate of speed for the trip if the aircraft can fly 225 mi/h with no wind.
Answers
9514 1404 393
Answer:
216 mi/h
Step-by-step explanation:
The time for the trip with the wind is ...
(1080 mi)/(225 +45 mi/h) = 4 h
The time for the trip against the wind is ...
(1080 mi)/(225 -45 mi/h) = 6 h
The average speed for the entire round trip is ...
(2160 mi)/(4 +6 h) = 216 mi/h
Avery earned a raise of an additional $2.50 per hour. Initially, she started at $10.00 an hour. What is the percent increase in Avery’s hourly pay?
Answers
Explanation:
1. Turn it into a fraction (2.50/10)
2. Divide the numerator (2.50) by the denominator (10). (2.50÷10=0.25)
3. Convert the decimal (0.25) into a percentage by multiplying it by 100 and placing “%” at the end. (0.25x100=25%)
how do you work out this equation?
solve simultaneous equations by substitution
x + y =3
5x + y = 15
Answers
Step-by-step explanation:
x + y = 3. => y = 3 - x
5x + y = 5x + (3 - x) = 15.
=> 4x + 3 = 15
=> 4x = 12, x = 3.
Therefore y = 3 - (3) = 0.
The solutions are x = 3 and y = 0.
Answer:
Step-by-step explanation:
x+y=3
5x+y = 15
I method:
y = 3 - x. substitute this in 2nd equation
5x + (3-x) = 15
5x + 3 - x = 15
4x = 12
x=3
y=0
II method:
subtracting 2nd equation and 1st equation we get
4x +0y = 12
x = 3
y = 0

The prism shown has a volume of 35 cm'.
Work out h, the height of the triangular cross section.
h

4 cm
Answers
The height of the triangular cross section of the prism will be [tex]2.5 \ cm[/tex] .
What is prism ?Prism is a polyhedron comprising an [tex]n-[/tex]sided polygon base, a second base which is a translated copy of the first, and [tex]n[/tex] other faces, necessarily all parallelograms, joining corresponding sides of the two bases. All cross-sections parallel to the bases are translations of the bases.
And,
Volume of prism [tex]= Base\ Area\ *\ Length[/tex]
We have,
Volume of prism [tex]=35 cm^3[/tex]
Length of prism [tex]=7cm[/tex]
Height of prism [tex]=h\ cm[/tex]
We also have,
Base of triangle [tex]=4\ cm[/tex]
One of the side of triangle [tex]=5\ cm[/tex]
As we have Triangular prism so Base area of prism will be the area of triangle.
so,
Area of triangle [tex]=\frac{1}{2}*base*Height[/tex]
[tex]=\frac{1}{2} * 4*h[/tex]
Area of triangle [tex]=2h[/tex]
Now,
Volume of prism [tex]= Base\ Area\ *\ Length[/tex]
[tex]35=2h*7[/tex]
[tex]h=\frac{5}{2}[/tex]
[tex]h=2.5 \ cm[/tex]
So, the height of prism is [tex]2.5\ cm[/tex] .
Hence, we can say that the height of the triangular cross section of the prism will be [tex]2.5 \ cm[/tex] .

Find the common difference of the arithmetic
sequence 13,9,5,
Answers
Answer: -4
Step-by-step explanation:
13 - 9 = 4
9 - 5 = 4
so, we can see that it is decreasing by 4 each time.
Answer:
common difference is -4
Step-by-step explanation:
The common difference is the amount we add between terms
13 + d = 9
Subtract 13 from each side
13+d-13 = 9-13
d = -4
Check
9+d = 5
9 + -4 = 5
5= 5
This is true so the common difference is -4

y- x-3 and x = -10
0 (-10,-7)
0 (-10,-1)
0 (-7, -10)
0 (-1,-10)
Answers
Answer:
(-10,-7)
Step-by-step explanation:
the given equations: y=-3 and x=-10
we can substitute the x in the first equation as -10.
y=(2/5×-10)-3
simplify
y=(2/1*-2)-3
y=-4-3
y=-7
the y value is -7
we actually have the x value given as -10 (in the system)
So the answer is (-10,-7)
