Answer:
what do u need help with?? :)
Step-by-step explanation:
If 7x+3=24, that means x would be 3 so if you take 5-4x then that would be -7.
Answer:
x = 28
Step-by-step explanation:
7(8 - x) = -5x
56 - 7x = -5x Distribute 7 to the parenthesis
56 = 2x Add -7x to both sides
28 = x Divide 2 to both sides
Estimate 189 to the nearest tenth which would be 190. And then do the same for 643 which would be 640. 640-190= 450
