Answer:
x = 2
Step-by-step explanation:
Given
- 7x - 3x + 2 = - 8x - 2 ← simplify left side
- 10x + 2 = - 8x - 2 ( add 8x to both sides )
- 2x + 2 = - 2 ( subtract 2 from both sides )
- 2x = - 4 ( divide both sides by - 2 )
x = 2
At first take the 2 to the other side and substitute to 4
X^2 = 8^2 + 5^2
x^2 = 64 + 25
x^2 = 89
x =

The answer is d because 7=7 and whenever the two numbers equal each other, then all values of x are true, but when they don't equal each other then No values of x are true
Answer: 152$
Step-by-step explanation:
255 x (1/3) = 85
85
110 of the coins are 50p
110 x .5 = 55
85 + 55 = 140
85 + 110 = 195 total coins
255 - 195 = 60
60 x .2 = 12$
140 + 12 = 152$
