Answer:

A's received by Dina is 35.

Step-by-step explanation:

Given

number of A’s received by Pete, Chris, and Dina on their report cards were in a ratio of 4:2:5.

Let the

A's received by Pete = 4x

A's received by Chris = 2x

A's received by Dina = 5x

This, is done so that ratio of 4:2:5 remains intact.

Now, given Pete got 14 more A’s than Chris got

Thus, writing it mathematically

A's got by Pete = A's got be Chris + 14

we will be using A's got Pete and Chris in term of x as defined above

4x = 2x+ 14

=> 4x - 2x = 14

=> 2x = 14

=> x = 14/2 = 7

A's received by Dina = 5x = 5*7 = 35( Answer).

Martin combined different amounts of orange juice, pineapple juice, and strawberry juice to make 1850 milliliters (ml) of fruit

stealth61 [152]

The answer is 450 ml.

First, we need to solve x (the amount of orange juice):
x + (x + 100) + one half x = 1850
x + x + 100 + 1/2 x = 1850

We can represent 1/2 as 0.5:

2x + 100 + 0.5x = 1850
2.5x = 1850 - 100
2.5x = 1750
x = 1750 ÷ 2.5
x = 700.

Thus, in the fruit punch, there is 700 ml of orange juice.

The amount of pineapple juice combined was 100 ml more than the amount of orange juice. Therefore, there is 800 ml of pineapple juice (700 ml of orange juice + 100 ml more).

The amount of strawberry juice was half the amount of orange juice. Therefore, there is 350 ml of strawberry juice (700 ml of orange juice ÷ 2).

The difference in the amounts of pineapple juice and strawberry juice Martin combined is 450 ml:
the amounts of pineapple juice - the amounts of strawberry juice =
800 ml of pineapple juice - 350 ml of strawberry juice = 450 ml.
