P = pizza and c =cakes
Last week: 8p + 13c = 134
Today: 28p + 4c = 220
Let’s take the formula for today and subtract 28p from each side to isolate the 4c.
4c = 220 - 28p
Now divide each side by 4
c = (220 - 28p)/4
Simplify to c = 55 - 7p
Now go to the formula for last week, substitute the c for 55-7p
8p + 13(55 - 7p) = 134
8p + 715 - 91p = 134
Simplify to 715 - 83p = 134
Let’s add 83p to each side.
715 = 134 + 83p
Subtract 134 from each side
581 = 83p
Divide each side by 83
p = $7
Answer:
The inverse operation of squaring a number is finding the square root of a number. The square root cancels out the square. For example, 3² = 9. To cancel out the square, we have to take the square root. So, √9 = 3. Hope this helped.Step-by-step explanation:
Order of operations
first divide, than add
35/5 = 7
56/7 = 8
7 + 8 = 15
15 is your answer
