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
Answer:
A) 2p
(because DC is twice the size of AB. Hence why they're in the ratio of 2:1)
B) p+q
(Start from B, go backs against the arrow to the left and get - p, then + q and + 2p. Simplify -p+q+2p)
Hope this helps!
Answer:
72 houses.
Step-by-step explanation:
We are told that a postal worker can deliver the mail to 18 houses in 15 minutes.
Let us find numbers of mails delivered by postal worker per minute.
Since we know that 1 hour equals 60 minutes, so we will multiply 1.2 by 60 to find the number mails postal worker will deliver in 1 hour.
Therefore, the postal worker will be able to deliver mails to 72 houses in 1 hour.
I can't understand what you wanted with the second question (or if that is even a question), but the answer to the first one is 42.
