1. Dalia makes a cranberry apple punch that contains 20%, percent real juice by mixing x gallons of a cranberry drink with y gal
Vladimir79 [104]

Answer:

The required equations which represents the relationship between x and y is 0.2(x+y)=0.4x+0.1y.

Step-by-step explanation:

Consider the provided information.

Dalia makes a cranberry apple punch that contains 20%, percent real juice by mixing x gallons of a cranberry drink with y gallons of an apple drink.

This can be written as: \frac{20}{100}(x+y)

The cranberry drink contains 40 percent real juice and the apple drink contains 10 percent real juice.

This can be written as: \frac{40}{100}x+\frac{10}{100}y

Now both the equation are equal.

\frac{20}{100}(x+y)=\frac{40}{100}x+\frac{10}{100}y

0.2(x+y)=0.4x+0.1y

Hence, the required equations which represents the relationship between x and y is 0.2(x+y)=0.4x+0.1y.

Please Help, Lots of points
Andrei [34K]

Answer:

9 cats

Step-by-step explanation:

x = cat

y = dog

Set up equations.

x + y = 30

4.5x + 8.5y = 219

Multiply first equation by 4.5 and subtract.

4.5x + 4.5y = 135

-(4.5x + 8.5y = 219)

-4y = -84

y = 21

Substitute this y value into the first equation

x + y = 30

x + 21 = 30

x = 9
