Solve for the value of y. 60° (8y-2)

rusak2 [61]

Since it's a right angle the sum of the two angles equals 90°
(8y-2)°+60°=90°
8y-2=90-60
8y-2=30
8y=30+2
8y=32
y=32/8

What is the solution to the equation? 7x + 6 = -22

trapecia [35]

C.) x = -4 is the correct answer

Step-by-step explanation:

In order to solve the equation we have to isolate x on one side of equation

Given

7x + 6 = -22

Subtracting 6 from both sides

$7x+6-6=-22-6\\7x=-28$

Dividing both sides by 7

$\frac{7x}{7}=\frac{-28}{7}\\x=-4$

Hence,

C.) x = -4 is the correct answer
