Answer: p = -2w + 20
<u>Step-by-step explanation:</u>
If the student had 20 pencils but now has 18 pencils, he uses pencils at a rate of 2 per week. So, m = -2 (negative because he is decreasing the amount of pencils). The student started with 20 pencils so b = 20
Use the y = mx + b but replace "y" with "p" and replace "x" with "w" and input the m and b as stated above:
p = -2w + 20

Answer:
Height of prism (H) = 2.5 cm
Step-by-step explanation:
Given:
Base of rectangle (b) = 4 cm
Length of rectangle (l) = 7 cm
Volume of prism = 35 cm³
Find:
Height of prism (H)
Computation:
Volume of prism = 1/2 × b × l × H
35 = 1/2 × 4 × 7 × H
35 = 14 × H
Height of prism (H) = 2.5 cm
