Answer:
Pies=$0.85
Donuts= $1.20
Step-by-step explanation:
In the equation let p stand for the number of pies and d stand for the number of donuts.
To solve this set up 2 equations, one representing bill and the other representing Mary Ann.
- Bill's equation is 5p+7d=$12.65.
- Mary Ann's equation is 6p+6d=$12.30
Then solve using a system of equations. Systems of equations can be solved using elimination or substitution. I will use substitution. Solve bill's equation for p. This gives you . Then, you can substitute that into Mary Ann's equation. This looks like . Solve for d. Once you solve d=1.20. Finally, substitute 1.20 back into either Bill's or Mary Ann's for d and solve for p. No matter which equation you use p=0.85.
Answer:
x = 60
Step-by-step explanation:
to solve this simple expression, you will collect the like terms and then evaluate for the value of x
<u>solution</u>
8.4 + 0.18x =0.32x
8.4 = 0.32x - 0.18x
8.4 = 0.14x
divide both side by the coefficient of x
8.4/0.14 = 0.14x/0.14
60 = x
x = 60
to check if the answer is correct put the value of x = 60 into the question and check if the right handside is equal to the left handside.
8.4 + 0.18x =0.32x
8.4 + 0.18 × 60 = 0.32 × 60
8.4 + 10.8 = 19.2
19.2 = 19.2................................................................................ proved
