Answer: 30 pounds of coffee beans worth $10.50 per pound was used.
20 pounds of coffee beans worth $13.00 per pound was used.
Step-by-step explanation:
Let x represent the number of coffee beans worth $10.50 per pound that should be mixed.
Let y represent the number of coffee beans worth $13.00 per pound that should be mixed.
50 pounds of beans worth $11.50 per pound is to be made. The total cost of the mixture would be
50 × 11.5 = 575
This means that
10.5x + 13y = 575 - - - - - - - 1
The total number of pounds of each type of coffee used is 50. This means that
x + y = 50
Substituting x = 50 - y into equation 1, it becomes.
10.5(50 - y) + 13y = 575
525 - 10.5y + 13y = 575
- 10.5y + 13y = 575 - 525
2.5y = 50
y = 50/2.5 = 20
x = 50 - 20= 30
The picture in the attached figure
we know that
<span>the diameter divides the circle into two equal parts
so
if </span><span>rt is a diameter and rt is perpendicular to UV
then
SV=US
SV=9 units
the answer isSV=9</span>
Answer:d. W=20m
Step-by-step explanation:
w=20(1), 1 minute is 20 words
W=20(2) 2 minutes is 40 words
W=20(3) 3 minutes is 60 words
And so forth....
Answer: 47.5
Step-by-step explanation:
Given
2x-10+x+x=180
combine like term x
4x-10=180
addition property of equality (add 10 on both sides)
4x=190
division property (divide 4 on both sides)
x=47.5
