Here's an example
Y=5x + 10
if x is equal to 5 you would make it
Y=5(5)+10.
basically, just replace the x with what it's equal to.
I'm sorry but what are we answering? i'd love to help but i'm confused
The equations and the number of hotdogs and sodas sold are: x+ y = 126 and 2.25x + 1.50y = 225.75 ; 49 hot dogs and 77 sodas.
Two equations can be derived from this question:
2.25x + 1.50y = 225.75 equation 1
x + y = 126 equation 2
Where:
x = number of hotdogs sold
y = number of soda sold
In order to determine the value of y, multiply equation 2 by 2.25
2.25x + 2.25y = 283.50 equation 3
Subtract equation 1 from 3
57.75 = 0.75y
y = 77
Substitute for y in equation 2
x + 77 = 126
x = 49

Answer:
Angle made by ramp with ground is ≈
Step-by-step explanation:
Diagram of given scenario is shown below.
Given that,
Horizontal Distance of Skateboard ramp is ft.
Height of Skateboard ramp is ft.
From figure,
It is forming a Right angle triangle .
In , and .
Clearly see that we need to find measure of angle .
Using Trigonometric ratio:
So,
Then
Therefore, Angle made by ramp with ground is ≈
2/5 (-7) 5/2 as you know 2/5 x 5/2 = 1
so 1 x (-7) = -7
so the asnwer is -7
