Answer:
(7,5)
Step-by-step explanation:
2(12 - y) + 3y = 29
24 - 2y + 3y = 29
24 + y = 29
y = 5
x = 12 - 5
x = 7
14.05 at most
If it is saying at least, than it would be in the cooler for longer than it should be and drop below 60.5
If saying more than 14.05, it is basically the same thing where it is inside the cooler for longer than it should be
If saying at most, that means that 14.05 is the max it would be in the cooler and keeps the liquid above 60.5
Answer:
2/45
Step-by-step explanation:
Multply both equations by 2 leaving
x + 2y = 8
x - 2y = -2
Add the equations giving
2x = 6
x = 3
Substitute 3 in the top equation
3 + 2y = 8
2y = -5
y = -2.5
Answer:
The surface area of the rectangular prism is 124in³
Step-by-step explanation:
To calculate the surface area of a rectangular prism we have to use the following formula:
a = area
w = width = 1in
l = length = 6in
h = height = 8in
A = 2wl + 2lh + 2hw
we replace the values that we know
a = 2 * 1in * 6in + 2 * 6in * 8in + 2 * 8in * 1in
a = 12in ² + 96in ² + 16in ²
a = 124in³
The surface area of the rectangular prism is 124in³
