(a) Each case of fruit costs $13
∴ $13 × f cases
= 13f
(b) Since f = 250
= 13(250)
= $3250
X + 4 = 4x + 2
let’s put the x’s on one side and the numbers on the other
(whatever you do to one side, you have to do to the other)
x + 4 = 4x + 2
- 4 - 4x
x - 4x = 2 - 4
-3x = -2
—— ——
-3 -3
x = 2/3
to check this, we can put 2/3 in for x
(2/3) + 4 = 4(2/3) + 2
4 2/3 = 8/3 + 2
4 2/3 = 2 2/3 + 2
and there we can see both sides equal 4 and 2/3, making it true
L = 2w
perimeter = 2l + 2w = 6w
6w = 54
w = 9
the right answer is 12 and if you ever need more help just use the app mathaway
Multiply $9700 by 11% to get the annual interest, then divide by 12 months in year and multiply by # of months.
9700 * .11 = 1067
1067/12 = 88.9166666
88.9166666*3= $266.75
