Aleks [24]

Answer:

10 cups of canberry juice

Step-by-step explanation:

Given that  for every 3 cups of punch, he uses 2 cups of cranberry juice.

3 cup's of punch ---> 2 cups of canberry juice

15 cups's of punch ----> x cups of canberry juice

on cross multiplication we get

3\times x=15\times2

x = 10

postnew [5]

Answer:

The numbers are 20 and 140

Step-by-step explanation:

<u><em>The question in English is</em></u>

Find 2 numbers knowing that the second number is 7 times greater than the first, and the sum between the double of the first number and the triple of the second is 460

Define the variables

Let

x ----> the first number

y ----> the second number

we know that

y=7x -----> equation A

2x+3y=460 ----> equation B

Solve the system of equations by substitution

Substitute equation A in equation B

2x+3(7x)=460

solve for x

2x+21x=460

23x=460

x=20

<em>Find the value of y</em>

y=7x  ----> y=7(20)=140

The numbers are 20 and 140
