Answer:
10 lb of cashews and 70 lb of peanuts
Step-by-step explanation:
Let x = the pounds of cashews.
Then 80 – x = the pounds of peanuts
Value of cashews + value of peanuts = volume of mixture
x×4.75 + (80 – x)×2.75 = 80×3 Remove parentheses
4.75x + 220 - 2.75x = 240 Combine like terms
2.00x + 220 = 240 Subtract 220 from each side
2.00x = 20 Divide each side by 2.00
x = 10 lb
80 - x = 80 – 10
80 - x = 70 lb
Max will mix 10 lb of cashews with 70 lb of peanuts.

<em>Check:
</em>
10×4.75 + 70×2.75 = 80×3.00
47.50 + 192.50 = 240.00
240.00 = 240.00
Answer:
a) 2x - 3y + 8
Step-by-step explanation:
Problem: 2x + y - 4y + 8
Solve: y - 4y
Put it back into the expression: 2x - 3y + 8
I’m pretty sure it’s 14 km. Hope I helped :) Since I did 56 divided by 4 since it will be one cm is 14 km.
You can't factor anything out of this except for a number. In this case, you can factor out a four. 16/4=4 40/4=10. This written out should look like 4(4x+10y), and that is your answer.
