Answer:

A) 8x - 5y = 3

Step-by-step explanation:

To create infinite solutions, the equation has to be the same line

First we can reduce the equation by dividing by 5

40x -25y =15

40/5 x -25/5 y =15/5

8x-5y =3

This is the same line , so if this is the second equation, it will give us infinite solutions

Nikolay [14]

Answer:

5/12

Step-by-step explanation:

Given

Fraction of punch that is pineapple juice = 1/4

Fraction of punch that is orange = 1/6

Taking the sum;

fraction of the punch that is pineapple juice or orange juice = 1/4 + 1/6

fraction of the punch that is pineapple juice or orange juice = 3+2/12

fraction of the punch that is pineapple juice or orange juice = 5/12

Hence the fraction of the punch that is pineapple juice or orange juice is 5/12

attashe74 [19]

Answer:

There are 18 dimes in the jar

Step-by-step explanation:

Let

x = number of dimes in the jar

y = number of quarters in the jar

Total = $3.80

There are ten less quarters than dimes

y = x - 10

0.1x + 0.25y = 3.80

0.1x + 0.25(x - 10) = 3.80

0.1x + 0.25x - 2.5 = 3.80

0.35x = 3.80 + 2.5

0.35x = 6.30

x = 6.30/0.35

x = 18
