It’s 28 because it makes sense
Answer:
- 3 pounds at $3.87
- 19 pounds at $0.94
Step-by-step explanation:
Let x represent the number of pounds of high-priced jelly beans sold. Then the total revenue was ...
3.87x + 0.94(22 -x) = 29.47
2.93x + 20.68 = 29.47 . . . . . . eliminate parentheses, collect terms
2.93x = 8.79 . . . . . . . . . . . . . . subtract 20.68
x = 3 . . . . . . . . . divide by 2.93
3 pounds of $3.87 jelly beans were sold; 19 pounds of $0.94 jelly beans were sold.
X= 65
Explanation:
Simplify both sides of equations
3(x)+7)(2)+8=440
6x+42+8=440 (Distribute)
(6x)+(42+8)=440
(Combine Like Terms)
Step 2: subtract 50 from each side
6x+50−50=440-50 6x=390
Step 3: Divide both sides by 6
6x/6 = 390/6
Answer:
Step-by-step explanation:
-3x + 4y = 12
12(1/4x - 1/3y = 1)
-3x + 4y = 12
3x - 4y = 12
there is no solution
