Answer:
31.5 cubic feet
Step-by-step explanation:
the formula to find the volume of a rectangular prism is v = <em>whl</em>
w = width
h = height
l = length
(3.5)(2)(4.5) = 31.5
Answer:
A, C, E
Step-by-step explanation:
-4 + (4+5) = 5
A: (4 - 4) + 5 = 5, equivalent
B: (-4 - 4) + 5 = -3, not equivalent
C: -(4-4) + 5 = 5, equivalent
D: -(4) + (-4) + 5 = -3, not equivalent
E: -4 + 4 +5 = 5, equivalent
Answer:
c 2:1
Step-by-step explanation:
8/4=2
4/4=1
8:4 simplified is 2:1
x will represent the number of tickets.
y will represent the fixed fee given by the ticket agency
6x + y = 135
3x + y = 75
To solve, we can use the process of elimination by multiplying the second equation by -2 so that 6y will cancel:
-6x - 2y = -150
+6y + y = 135
Now we simplify by adding/subtracting:
-y = -15 or y = 15
Plug the value of y into any of the two equations and solve for x. I will use the second equation:
3x + 15 = 75
3x = 60
x = 20
To set this up in slope intercept form (y = mx + b), we need to identify what m and b are.
m is x because it is not a fixed number, and b is y because it is a fixed number (price of “fixed” fee). This brings us to y = 20x + 15
