Answer:
i Don't understand
Step-by-step explanation:
<span>The expression 81xy/3x and 9xy , divide it by 3 & cancel out 3x/3x to get 27y. 27y does not equal 9xy, so the expressions are not equivalent</span>
(5s)/7=30
mutiply both sides by 7, that makes it cancel the fraction
(5s)7/7=30 times 7
5s times 7/7=210
5s times 1=210
5s=210
divide both sides by 5
5s/5=210/5
s times 5/5=42
s times 1=42
s=42
Answer: <u>$630.00</u>
Step-by-step explanation:
25 x 9.00= 225.00
15 x 8.00= 120.00
23 x 15.00= 345.00
225.00 + 120.00 + 345.00= 690.00
690.00 - 60.00= <u>$630.00</u>
