<span>3 3/5-1 1/2
= 3 6/10 - 1 5/10
= 2 1/10
answer
</span> 2 1/10
Answer: if 0 < x ≤ 450, y = $60.
if 450 < x ; y = $60 + (x - 450min)*$0.35
Step-by-step explanation:
Here x will represent the number of minutes.
with $60 you have 450 minutes, and you must pay 60 regardless of how much minutes you use.
so if 0 < x ≤ 450, y = $60.
now, if you call for more than 450 minutes, you get an additional of $0.35 per minute, then we have:
if 450 < x ; y = $60 + (x - 450min)*$0.35
where we use (x - 450)*$0.35 because any minute after the 450 minute mark is considerated an additional time.
So our piecewise function is:
if 0 < x ≤ 450, y = $60.
if 450 < x ; y = $60 + (x - 450min)*$0.35
Answer:
B.) 317
Step-by-step explanation:
100/2 = 50
124/2 = 62
180/2 = 90
634/2 = 317
X + 5x - 13 = 140
6x - 13 = 140
6x = 153
x = 25.5
5(25.5) -13 = 114.5
CHECK: 25.5 + 114.5 = 140
