Answer:
When x = 12, y = 4, and z = 2, 8x + 2yz = 112.
Step-by-step explanation:
8x + 2yz
Substitute variables given:
x = 12
y = 4
z = 2
8(12) + 2(4)(2)
Multiply 8 and 12.
96 + 2(4)(2)
Multiply 2 and 4.
96 + 8(2)
Multiply 8 and 2.
96 + 16
Add 96 and 16.
112.
Answer: 50 students
Step-by-step explanation:
You know that the number of students last year plus 20% of that number equals the number of students this year, which can be written as: x + 0.2x = 60 →
1.2x = 60 → x = 50 students :)
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.
