That would be M = 30G where M is in miles and G is in gallons.
The addition property of equality justifies this. You could also say that she simply subtracted 7, and then it would be the subtraction property of equality. This is the case because if you add or subtract (or multiply or divide) the same number on both sides of an equation, the equation will still be the same.
Hope it helps!
Answer:
Michaela gets 3.45$ back.
Step-by-step explanation:
1 carton of eggs = 1.58$
she buys 2, so 2 times 1.58= 3.16$
1 pound of turkey = 6.99$
she buys 4.15 pounds, so 4.15 times 6.99= 29.01$
she buys a jar of jam for 4.38$
4.38 + 3.16 + 29.01 = 36.55$
4 times 10= 40
40 - 36.55 = 3.45$
Depends on what the measurement is.
