3 hours and 20 minutes minus 1 hour and 48 minuets equals an hour and 32 minutes. There are 60 minuets in an hour and 60 divided by 32 is 0.53. This means that your final answer is:
D. 1.53
Answer:
20 dimes and 2 quarters
Step-by-step explanation:
x = number of dimes
y = number of quarters
minimum is greater than or equal to ≥
x+y ≥16
no more than is less than or equal to ≤ ,
value of dime is $ 0.10
value of quarter is $0.25 so
0.10x + 0.25y ≤ 3.00
Rewrite inequalities in terms of y:
y ≥16 - x
(0.25/0.25)y ≤ (3.00/0.25)-(0.10/0.25)x→
y≤12 - 0.4x

(87+91+86+x)/4=90.
x=96.
13.
50×y > 130.
the lowest number could be 3, because 50×2=120, which is less than 130.
v + 9 / 3 = 8
v + 9 = 24
v = 24 - 9
v = 15
