Answer:
1563
Step-by-step explanation:
x= 1 bag of bananas
so, 4x=2084
Divide 2084 by 4 to find how much 1 bag of bananas would cost. 2084/4= 521.
To find how much 3 bags of bananas would cost, multiply 521 (the price of one bag) by 3. 521x3= 1563
3 bags of bananas are $1563
Answer:
Step-by-step explanation:
<u>z is directly proportional to x</u>
- z = kx, where k is coefficient
If z = 12 when x = 3
<u>Then we have</u>
So the coefficient is 4
<u>When z = 18, we have</u>
X(x+1) = 306
Distribute the x
x² + x = 306
move all terms to the left and set the equal to zero (be sure to change the sign for all terms moved)
x² + x - 306 = 0
x -17
x 18
(x - 17)(x + 18)
x = -18, 17
