Shea bought 13.5 pounds of corn
c = pounds of corn
b = pounds of beans
Here’s what we know:
c(0.99) + b(0.45) = 18.09
c + b = 24
Solve the second equation for c in terms of b
c = 24-b
Substitute that expression for c in our first equation to get a numerical solution for b:
0.99 (24-b) + 0.45b = 18.09
23.76 - 0.99b + 0.45b = 18.09
-0.54b = -5.67
b = 10.5
Substitute that value to get a numerical value for c:
c = 24 - b
c = 24 - 10.5
c = 13.5
Check the math:
0.99(13.5) + 0.45(10.5) =
13.365 + 4.725 = 18.09
A number - n
five times the number - 5n
nine more than five times the number - 5n+9
The answer is D.
Answer:
— 3 (1.5n — 1)
Step-by-step explanation:
1 beehive produces 85 lb/year
10³ beehives = 1,000 beehives produce 85x1,000 = 85,000 lb/year
