Answer:
2,650 pounds
Step-by-step explanation:
Given data
Amount paid= $848
Rate = 32 cents= $0.32
Hence the amount she purchased is
Quantity= Amount* Rate
Quantity = 848/0.32
Quantity= 2650
Answer:
The copy machine makes 32 copies per minute.
Step-by-step explanation:
Given that a copy machine makes 136 copies in 4 minutes and 15 seconds, to determine how many copies does it make per minute, the following calculation must be performed:
15 seconds = 0.25 minutes
136 / 4.25 = X
32 = X
Therefore, the copy machine makes 32 copies per minute.
Answer:
Height = 13.86 cm
Step-by-step explanation:
1. Find the length of each side
48/3 = 16
2. cut the triangle in half.
Base = 8 Hypotenuse = 16
3. use the formula A^2 + B^2 = C^2
(16^2 - 8^2)^(1/2) = 13.86 cm
We can isolate y in the linear equation to get:
y = 4x - 8
<h3>How to isolate the variable?</h3>
Here we have the linear equation:
8x - 2y = 16
Now, remember that we can perform the same operation in both sides of the equation, and the equation don't changes.
To isolate y, we can start by subtracting 8x in both sides, so we get:
-2y = 16 - 8x
Now we should divide both sides by -2:
y = (16 - 8x)/(-2) = -8 + 4x
y = 4x - 8
