Answer:

x = 20

Step-by-step explanation:

Using the vertical angle theorem, you will find that 7x - 99 = 2x + 1.

7x - 99 = 2x + 1

+99 both sides

7x = 2x + 100

-2x both sides

5x = 100

÷5 both sides

x = 20

The answer is x = 20.

sarah meeham blends coffee for tasti delight. she needs to prepare 160 pounds of blended coffee beans selling for $4.97 per poun
Viefleur [7K]
Given:
h = high quality bean ; costs 6 per pound
c = cheaper bean ; costs 3.25 per pound

160 pounds of blended coffee beans at 4.97 per pound

h + c = 160

6h + 3.25c = 160(4.97)
6h + 3.25c = 795.20

h = 160 - c

6(160-c) + 3.25c = 795.20
960 - 6c + 3.25c = 795.20
- 2.75c = 795.20 - 960 
- 2.75c = -164.80
c = - 164.80 / -2.75
c = 59.92 or 60 pounds

h = 160 - c
h = 160 - 60 
h = 100 pounds

Sarah must blend 100 pounds of high quality bean and 60 pounds of cheaper bean.
