Step-by-step explanation:
<u>Step 1: Define</u>
(-4x + 4.2y) - (-7x + 3.4y)
<u>Step 2: Simplify</u>
- [Distributive Property] Distribute negative: -4x + 4.2y + 7x - 3.4y
- Combine like terms (x): 3x + 4.2y - 3.4y
- Combine like terms (y): 3x + 0.8y
All definitions can be read as a conditional statement
72 as Damon spend 2 and 15 minutes exercising so for the two dull hours you add 64 now that done and as 15 is 1/4 of 60 you add 8 which is 1/4 of 32 and get 72
3+3=6 therefore the answer would be 6x.
