Answer:
Horizontal line parallel to X axis
Step-by-step explanation:
Horizontal line parallel to X axis
So the equaiton is
number of nickes=n
number of quarters=q
if you have 1 quarter then you have 25 cents so we will represent like this
25q
and nickles is 5n
14.50=1450 cents
so
25q+5n=1480
q+n=88
subtract q from both sides
n=88-q
subsitute into first equation
25q+5(88-q)=1480
25q+440-5q=1480
add like terms
20q+440=1480
subtract 440 from both sides
20q=1040
divide both sdies by 20
q=52
there were 52 quarters
25(52)+5n=1480
1300+5n=1480
subtract 1300 from both sides
5n=180
divide both sides by 5
n=36
there were 36 nickels
nickles=36
quarters=52
0.44 / (0.06 + 0.09) = 0.44 / 0.15 = 2.93....about 3 hrs
There number rounds to 3000 so divide that by 11 and round up your answer
have a good day!!
