X*y=72
x = 5y-2
x=72/y
72/y=5y-2
72=5y^2-2y
5y^2 -2y - 72 = 0
(5y+18)(y-4)=0
y = -18/5 discard
or y = 4
4x=72
x=18
(18,4)
Answer:
298
Step-by-step explanation:
given data
total friend = 4
total profit in the first month = 438
two months each friend profit = 184
solution
we consider here total profit second month is = x
so
profit second month = 184 × 4 - 438
x = 736 - 438
x = 298
so that here profit that car wash making the second month is 298
No simple form but is 53.33333333 as a decimal.
Ratio 1:5....added = 6
complimentary angles, when added, = 90 degrees
1/6(90) = 90/6 = 15
5/6(90) = 450/6 = 75
so ur 2 angles are : 15 and 75
Answer:
If he earns (e) $7.75 per hour, this implies e = 7.75h.
Step-by-step explanation:
If you wanted to solve that-
e = 7.75h
193.75 = 7.75h
Divide both sides by 7.25
h = 25
