Answer:
x= 3/5
Step-by-step explanation:
5(x+3)=30x
5x+15=30x
-5x -5x
15=25x
x= 3/5
Answer:
3/5
Step-by-step explanation:
5(x+3)= 30x [
or,
(5×x)+(5×3)= 30x
or,
5x+15= 30x
or,
5x+15-5x= 30x-5x [The result or root of the equation remains same . if we multiply, divide, add or subtract any . number from each side of the equation]
or,
15= 25x
or,
15/25= x
or,
3/5= x
So, the value of x is 3/5

Find the value of X
(5x+4)°+(8x-71)°
Answer:
x = -4/5
Step-by-step explanation:
Solve for x:
(5 x + 4) (8 x - 71) = 0
Split into two equations:
5 x + 4 = 0 or 8 x - 71 = 0
Subtract 4 from both sides:
5 x = -4 or 8 x - 71 = 0
Divide both sides by 5:
x = -4/5 or 8 x - 71 = 0
Add 71 to both sides:
x = -4/5 or 8 x = 71
Divide both sides by 8:
Answer: x = -4/5 or x = 71/8

Write a complex number where the real component is 7 and the imaginary component is -13i
Answer:
z = 7 - 13i
Step-by-step explanation:
A complex number has the form
z = a + bi ( where a is the real part and bi the imaginary part )
Here a = 7 and bi = - 13i, thus
z = 7 - 13i
For the following right triangle, find the side length x.
Answer: 37
Step-by-step explanation:
Use A squared plus b squared equals c squared.
1. 35 squared is 1,225.
2. 12 squared is 144.
3. 144 plus 1,225 is 1,369. Now is 1,369 a square number?
Well the square root of 1,369, that's 37.
Is the statement true or false? If false, give a counterexample.
For all real numbers a, b and c, a(b + c) = ab + bc.
A. true
B. false; a(b + c) = ab − ac
C. false; if a = b = c = 1, then 1(1 + 1) ≠ 1(1) + 1(1)
D. false; if a = 1, b = 2, and c = 3, then 1(2 + 3) ≠ 1(2) + 2(3)
Answer:
D. false; if a = 1, b = 2, and c = 3, then 1(2 + 3) ≠ 1(2) + 2(3)
Step-by-step explanation:
A is false, because the a is being distributed/ being multiplied to all terms inside the parenthesis, and not the term b.
B is also false. There is no indicated negative signs.
C is also false because 1(1 + 1) is EQUAL to 1(1) + 1(1)
D is true.

Evaluate x/y when x=9/4 and y=3/5
Answer:
[tex]\displaystyle x/y=\frac{15}{4}[/tex]
Step-by-step explanation:
Division of fractions
To calculate the division of fractions a/b and c/d, it's usually easier to multiply a/b by the reciprocal of the denominator, that is:
[tex]\displaystyle \frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a}{b}\cdot \frac{d}{c}[/tex]
We will evaluate x/y when x=9/4 and y=3/5:
[tex]\displaystyle \frac{\frac{9}{4}}{\frac{3}{5}}=\frac{9}{4}\cdot \frac{5}{3}[/tex]
[tex]\displaystyle=\frac{45}{12}[/tex]
Simplifying:
[tex]\displaystyle \boxed{x/y=\frac{15}{4}}[/tex]

Suppose y varies directly as x. To solve you will need to find the constant of the
variation, write the equation so you can answer the question. If y = 4 when x = 2,
find y when x = 16.*
Answer:
32
Step-by-step explanation:
Given, y varies directly as x. So, y=kx, where k is the constant of proportionality.
Given, x=2, y=4. plug in the values in the equation.
4=k*2
k=4/2
k=2
x=16
y=2*16
y=32

Step-by-step explanation:
An animal shelter has $2500 in its reserve fund. The shelter charges $40 per animal placement and would like to have at least $4000 in its reserve fund. Write an inequality to represent this situation.
Answer:
Step 1
Write and solve the inequality:
2,500 + 40a ≥ 4,000, or 40a ≥ 1,500
a ≥ 37.5
Step 2
If the shelter places 30 cats and 10 dogs,
or 40 animals, that will be enough to meet
its goal, because a = 40 is a solution to the
inequality a ≥ 37.5.

The value of x is 0.57 in the given expression -0.8 x +40 - 8x -35
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is -0.8 x +40 - 8x -35
Minus zero point eight times of x plus forty minus eight times of x minus thirty five
-0.8 x +40 - 8x -35
Add the like terms
-0.8x-8x+40-35
-8.8x+5
Isolate the variable x
-8.8x=-5
Divide both sides by 8.8
x=5/8.8

per gallon of gasoline and he has some gasoline in his tank already. Matthew writes the
equation 25(x + 3) = 424, where x represents the number of gallons of gasoline he will need to purchase to
complete the trip.
Identify the meaning of each of the constants in Matthew's equation in the context of the problem, then solve
the equation to determine how many gallons of gasoline he must purchase.
Answer: 14 gallons of gasoline.
Step-by-step explanation:
given data:
25(x + 3) = 424
where x is the number of gallon of gasoline needed to purchase.
Solution.
25(x + 3) = 424
first we open the bracket
25x + 75 = 424
collect like terms
25x = 424 – 75
25x = 349
divide both sides by 25
25x/25 = 349/25
x = 13.96
x = 14
