Answer:

x= -1.2

Step-by-step explanation:

Simplifying

-7 + 12 + -2x = 23 + 13x

Combine like terms: -7 + 12 = 5

5 + -2x = 23 + 13x

Solving

5 + -2x = 23 + 13x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-13x' to each side of the equation.

5 + -2x + -13x = 23 + 13x + -13x

Combine like terms: -2x + -13x = -15x

5 + -15x = 23 + 13x + -13x

Combine like terms: 13x + -13x = 0

5 + -15x = 23 + 0

5 + -15x = 23

Add '-5' to each side of the equation.

5 + -5 + -15x = 23 + -5

Combine like terms: 5 + -5 = 0

0 + -15x = 23 + -5

-15x = 23 + -5

Combine like terms: 23 + -5 = 18

-15x = 18

Divide each side by '-15'.

x = -1.2

zhenek [66]

Answer:

The correct answer is:

r + 0.50 = 10.25: Subtract .50 from both sides. The answer is $9.75.

This is because Juan got a $0.50 raise which means that his new rate will be $0.50 more than his original rate (r).

The difference in the x- coordinates of two points is 3, and the difference in the y- coordinates of the two points is 6. What i
USPshnik [31]

Answer:

2

Step-by-step explanation:

Slope or gradient of a line is given by dividing change in y axis by the change in x axis. Slope is represented by m hence m=\frac {\triangle y}{\triangle x} where \triangle y is the change in y axis while \triangle x is the change in x co-ordinates. Substituting \triangle y with 6 units while 3 units substitute \triangle x then the slope will be m=\frac {6}{3}=2

Therefore, the gradient is 2

∠E and ∠F are vertical angles with m∠E=5x+10 and m∠F=7x−12 .<br><br> What is the value of x?
In-s [12.5K]
Vertical angles are equal...so set ur angles equal to each other and solve for x

5x + 10 = 7x - 12
12 + 10 = 7x - 5x
22 = 2x
22/2 = x
11 = x <==
