The first answer is 3/34 sec and the second answer is 15/34 sec.
Set up a proportion for these problems. For the first question,
340/1 = 30/x
Cross multiply:
340*x = 1*30
340x = 30
Divide both sides by 340:
340x/340=30/340
x = 30/340 = 3/34
For the second question,
340/1 = 150/x
Cross multiply:
340*x = 150*1
340x=150
Divide both sides by 340:
340x/340 = 150/340
x = 150/340 = 15/34
M=slope=2
y-intercept= -4
y=2x+(-4)
y=2x-4
Answer:
q = -15
Step-by-step explanation:
5q = -75
Divide both sides by 5 : q = -15
Answer:
need to work out how long it would take 1 person first.
9 X 5 = 45
1 person will take 45 hours
45/3= 15 hours
