Sometimes a diagram can be helpful. If x is the distance from the house to the parallel side of the fenced plot, then the total length of fence will be x + x + 30 (feet). Jane wants to find x such that this length is 100 (feet).
The appropriate equation is ...
... A. x + x + 30 = 100
Answer:
She spent 4 $10 bills and 3 $1 bills
Step-by-step explanation:
She used 7 bills and you have 3 $1 that makes the 3 of 43 then 4 $10 bills adds up to 40 so add 40 and 3 together you get the price of the shoes and if you add the 4 $10 bills and the 3 $1 bills you get 7
Answer:
12 pounds, 6 ounces.
Step-by-step explanation:
First, add up both the pounds. 6+5=11 . Then, add up the ounces. 7+15=22 To simplify, since ounces make up pounds, and 16 ounces are in one pound, you would do 22 divided by 16. This will end in a decimal so take the highest number of 16 that can go into 22, which is 1. Subtract 16 from 22 to get the new number of ounces. This would be 6. Then, add 1 to the number of pounds. This would be 12. The simplified/combined answer is 12 pounds and 6 ounces.
