Answer:
70 pounds of high-quality coffee bean and 60 pounds of cheaper coffee bean.
Step-by-step explanation:
Total coffee weight = 130 pounds
Blend Cost = $4.73
High quality bean (H) price = $6.00
Cheaper bean (C) price = $3.25
The weight used of both beans must add up to 130 pounds, while the products of each individual quantity by its cost must add to 4.73 multiplied by 130.
Multiplying the first equation by -3.25 and adding it to the second one:
Sarah should use 70 pounds of high-quality coffee bean and 60 pounds of cheaper coffee bean.
Answer:
100×712 is equal to 71200
so the equality of 712 is 71200
I think the first one is $70 and the second one is 1800, I can’t really read a part of it
Answer:
length = 13 feet and width = 5 feet
Step-by-step explanation:
let width be w then length is 2w + 3 ( 3 more than twice the width )
Equate the sum of length and width to 18, that is
w + 2w + 3 = 18, that is
3w + 3 = 18 ( subtract 3 from both sides )
3w = 15 ( divide both sides by 3 )
w = 5
That is the width is 5 feet and
length = 2w + 3 = (2 × 5) + 3 = 10 + 3 = 13 feet
