Answer:
None of them
Step-by-step explanation:
4х – 12 < 16 + 8x
-12 - 16 < 8x - 4x
-28 < 4x
-7 < x
x > -7
First integer in the solution set would be -6
Answer:
the answer is space
Step-by-step explanation:
Answer:
<u>372 ft</u>
Step-by-step explanation:
This can be solved through cross multiplication.
310ft/10sec= x/12sec
Multiply the values across from each other. (A good way to know you've done it properly is if the numbers you multiplied are in different measurements. ex: 1 value is feet, the other is seconds)
310 x 12 = 3720
Divide by the remaining value.
3720 / 10 = 372
We need to know the dimension of the paving stone.
For example, the paving stone is shaped like a rectangular prism with the following dimension.
Length = 10 inches
Width = 3 inches
Height = 2 inches
Volume of a rectangular prism = Length * Width * Height
V = 10 in * 3 in * 2 in
V = 60 in³
60 in³ / 4 in³ = 15
cost of paving stone = 2.50 + .18(15) = 2.50 + 2.7 = 5.20 per paving stone.
