Katie works part-time at a Fallbrook riding stable she makes $5 an hour for exercising horses and $10 an hour for cleaning stall

Nookie1986 [14]

In order to at least earn $90, Katie can work exercising horses for 6 hours and cleaning stalls for 6 hours.

Step-by-step explanation:

Let hours of exercising horses be x --> $5 per hour = 5x

Let hours of cleaning stalls be y --> $10 per hour = 10y

Total earning = $\geq 90$

Total hours = 12

Equation 1:

5x + 10y = $\geq 90$

Equation 2:

x + y $\leq 12$

1. Multiply equation 2 by -5

x + y $\leq 12$ (*-5)

5x + 10y = $\geq 90$

-5x - 5y $\leq -60$

5x + 10y = $\geq 90$

2. Solve

-5x + 5x -5y + 10y = -60 + 90

5y = 30

y = 6

x + y = 12

x + 6 = 12

x = 6

Therefore, in order to at least earn $90, Katie can work exercising horses for 6 hours and cleaning stalls for 6 hours.

Adding the equations to eliminate p would be the correct step because when you add the equations together, the variable p would cancel out and be eliminated leaving you with 2w=35 you can then solve for the value of w which you can then input to find the value of p, allowing you to solve for the values of both p and w.

Please Help!

First car is x
second car is y
25x+30y=1550
x+y=55
Multiply the second equation by -25 for elimination method to cancel out x
-25x-25y=-1375
Add the two equations
5y=175
y=35
Plug this value into the second equation
x+35=55
x=20

Final answers:
First car=20 gallons
Second car=35 gallons

Hi can anyone help me with my math? thanks x

Katen [24]

It's multily
f(x) time g(x) is basically what they wnat

so

(x^2+8x+15) times (5/(x^2-9))
hold a sec, first factor each
(x+3)(x+5) times 5/((x-3)(x+3))
we get
((x+3)(x+5)(5))/((x-3)(x+3))
(x+30 cancels out
((x+5)(5))/(x-3)
(5x+25)/(x-3)
