Answer:
158 quarters
54 dimes
Step-by-step explanation:
Let d = no. of dimes
q = no. of quarters
10d = value of all the dimes since each dime is worth 10 cents
and 25q = value of all the quarters since each quarter is worth 25 cents
$44.90 = 4490 cents
10d + 25q = 4490 d + q = 212
<u> - 10d - 10q = -2120</u>
15q = 2370
q = 158 quarters d + 158 = 212
d = 54 dimes

-3
Because -2^2-8+1
-2to the second power is 4
4-8=-4
-4+1=-3
This is the concept of algebra, the average number of muffins baked by each girl will be given as follows;
Muffins baked by Andrea=h muffins
Muffins baked by Violet =h-8
Average=(Total sum of numbers)/(Number of items)
total sum=h+(h-8)=2h-8
Number of items=2
thus;
average=(2h-8)/2=h-4
the answer in terms of h is (h-4)
