Answer:
25 and 21 hours respectively
Step-by-step explanation:
Let the number of hours worked by each welder be x and y respectively.
They worked a total of 46 hours. This means :
x + y = 46 hours.......(I)
Now, given their hourly charges, since we have the total amount of money realized, we can make an equation out of it. This means:
34x + 39y = 1669........(ii)
We then solve both simultaneously. From I, x = 46 -y
We can substitute this into ii
34(46 -y) + 39y = 1669
1564 -34y + 39y = 1669
5y = 1669 - 1564
5y = 105
y = 105/5 = 21
x = 46 - y
x = 46 - 21 = 25 hours
The numbers of hours worked by the welders are 25 and 21 respectively
(centimeter/minute): 17
(miles per hour): 0.00633799
Answer:
30691
Step-by-step explanation:
Answer:
y = 2/5x - 3
P (0,5)
parallel lines have equal slopes
slope intercept form of an equation
y = mx + b
m = slope, b = y-intercept
parallel to y = 2/5x - 3,
and through P(0, 5)
m = 2/5
y intercept = 5
so, the equation would be
D. y = 2/5x + 5
