False. If x=-3 and y=-6 and you substitute them into the equation they do not add up
Answer:
y=9 (x=-4.5)
Step-by-step explanation:
you have to split the equation up in order to solve
5y=45
divide by 5 on both sides
y=9
-10x=45
divide by -10
x=-4.5
I think b= -4.75 in this equation
Answer:
A
Step-by-step explanation:
Okay here's my reasoning:
they are telling us that 3 and 5 put together is 8. While this could be either A or D, this question has already told us that it equals 8. This equation is basically more better suited to 8=3+5 because this is show that 8 can be found by putting 3 and 5 together.
Hope this helps!
Answer:
a)
Let x = number of candy bars sold
Let y = amount of money earned
b)
y = 0.75x
c)
He should work at the car wash.
Step-by-step explanation:
a)
Let x = number of candy bars sold
Let y = amount of money earned
b)
$42.75/57 = $0.75
Each candy bar costs $0.75
We can confirm that by dividing $38.25/51 = $0.75
1 candy bar sells for $0.75
2 candy bars sell for $0.75 * 2
x candy bars sell for 0.75 * x, or simply 0.75x
The equation is y = 0.75x
c)
y = 0.75x
y = 0.75 * 36
y = 27
Larry raised $27 by selling candy bars last year. This year, he can earn more than that by working at the car wash.
He should work at the car wash.
