Answer:
2*5*7
Step-by-step explanation:
2*5=10
10*7=70
1+7/11 = 11/11+7/11 = 18/11
2+1/2 = 4/2+1/2 = 5/2
(18/11)/(5/2) = (18/11)*(2/5) = 36/55
Since we are finding the unit rate of the cost per comic, we will need to divide $5 by 20 comics which you will get 0.25 cents and divide $7.50 by 30 comics which you will also get 0.25 cents.Therefore, the unit rate and constant of proportionality is 0.25 cents.
$46.46 for both rooms to have carpet
45/75 = 30/x
30*75 = 2250/45 = 50
EF = 50 in.
