Answer:
b = 13
Step-by-step explanation:
the value of the discount is a constant, while the total cost of the books is a variable because it depends of the purchase
We can write this equation
5b - 7 = 58
Solve it
1) add 7 at both members
5b -7 + 7 = 58 + 7
5b = 65
2) divide both membera by 5
b = 13
Answer:
87.5 by 70 inches
Step-by-step explanation:
No options were given. So, I will calculate the minimum width
Given

Height = 70 in ---- of the printed logo
Required
Determine the dimension that keeps the requirement
Let x be the width of the printed logo.
So, the ratio can be represented as:

Equate both ratios

As fraction

Multiply through by 70


So, one of the dimension that meets the requirement is a width of 87.5 inches
Answer:
Depth = 5
Width = 4
Height = 4
Total = 80
Step-by-step explanation:
For depth, width, and height you just count
The total equals, depth times width times height = 5x4x4 = 80
The correct answer is 108°
90+36=126
180-126=54
54x2= 108°
