Answer
# of pennies :7
#of nickels :6
#of quarters:20
Step-by-step explanation:
24 and 42, I got this by multiplying 5 and 2 then doing the same thing to 7 and adding the sums. I used this method to find the perimeter of 10 and 12 as well.
Because AB is a midsegment, the length of AB is half he length of XZ so basically you do
2(3x-1)=34.
Divide 2 by both sides to get 3X-1=17
Add 1 to boh sides to get 3X=18
Divide 3 from boh sides to get X=6
Hope this helps :)
