Answer:
Hi there!
Your answer is:
x= 18
Step-by-step explanation:
3x+70=8x-20
Isolate x on left side
3x+70=8x-20
-8x -8x
-5x +70 = -20
Isolate whole numbers on right side
-5x +70 = -20
-70 -70
-5x = -90
Isolate x by dividing both sides by -5
-5x = -90
/-5
x= 18
If x- 7 = 14 then X = 21. so 21-2= 19. :)
Each sides are equal so the answer 400 cubic in
B) In y = 25x, the value of y is 25 times the value of x, and in y = x + 25, the value of y is 25 more than the value of x.
Out of all the answer choices, b makes the most sense.
25x can be translated as 25 times x.
x + 25 can be translated as 25 more than a number.
Hope this helps!
