Answer:
Barry had the following:
8 bananas
12 apples
20 kiwi
32 peaches
8 grapefruit
4 mangos
88 total
Step-by-step explanation:
Each of the amounts of fruit can be written in terms of one variable. Starting with bananas as 'x', we can then make different values of 'x' to produce all the other numbers of fruits:
bananas = x
apples = 2x (twice as many bananas)
kiwi = 2.5x (5/6 of applies and bananas combined = 5/6(3x) or 2.5x)
peaches = 3.5x + 4 (sum of bananas and kiwis plus four = x + 2.5x + 4)
grapefruit = x (half as many apples = 2x/2)
mango = 0.5x (20% of kiwi = (0.2)(2.5)x)
88 = x + 2x + 2.5x + 3.5x + 4 + x + 0.5x
88 = 10.5x
8 = x (bananas)
apples = 2x or 16; kiwi = 2.5x or 20, peaches = 3.5x + 4 = 32, grapefruit = x or 8, mangos = 0.5x or 4
The scale factor was D. 4. We can figure this out by multiplying 3 by 4 to get 12 and 1 by 4 which is 4 to get the dimensions of the larger triangle.
I hope this helped! :-)
7-6(x-3)+2
Multiply -6 and (x-3)
7-6x+18+2
