Jack can program an app in 3 hours. Chris can program the same app in 8 hours. How long would it take them to program the same a
pp working together?
1 answer:
Answer:
2 2/11 hours
Step-by-step explanation:
Let the number of hours
Jack spent programming his app = J
Chris spent programming his app = C
Total hours if they worked together = T
Hence,
1/T = 1/3 + 1/8
Lowest Common Denominator = 34
1/T = 8 + 3/24
1/T = 11/24
Cross Multiply
T × 11 = 1 × 24
T = 24/11
T = 2 2/11 hours
Therefore, it would take them to program 2 2/11 hours to program the same app working together

Answer:
y = (4/3)x - (22/3)
Step-by-step explanation:
If it's parellel than they have the same slope.
m = 4/3
y = mx + b
y = (4/3)x + b
2 = (4/3)(7) + b
(6/3) = (28/3) + b
-(28/3) -(28/3)
(-22/3) = b
4/5 which is equal to 0.8
The answer should be (5,3)
