Which expression is equivalent to (0.5x+7)−(1.2x−3)? (0.5x+1.2x)+(7+3)
(0.5x+(−1.2x))+(7+(−3))
(0.5x+(−1.2x))+(7+3)
(0.5x+1.2x)+(7+(−3))

(0.5x + 7) - (1.2x - 3)
= (0.5x + 7) -1(1.2x - 3)
= 0.5x + 7 - 1.2x + 3
= (Now, we will combine and group the like terms.)
= 0.5x - 1.2x + 7 + 3
= -0.7x + 10
So, in conclusion, the answer to this question is: -0.7x + 10 which is equal to the third expression: (0.5x+(-1.2x))+(7+3).
Glad I could help!

24x-300=60x+77

Step-by-step explanation:

We are required to eliminate the decimals from the expression:

.24x-3=.6x+.77

Since all the numbers have at maximum 2 decimals, we only have to multiply by 100:

100*(.24x-3)=100*(.6x+.77)

Operating:

100*.24x-100*3)=100*.6x+100*.77

24x-300=60x+77

The expression is now free of decimals.
