Answer:

12:13

Step-by-step explanation:

Q: 52% students from a college participated in a survey. What is the respective ratio between the number of students who did not participate in the survey to the number of students who participated ?

A: Participants = 52%

Non Participants = (100 - 52)% = 48%

That means the ratio of Participants to Non Participants will be 52:48.

Reducing to lowest term....

52:48 = 13:12.

1. Solve the system by substitution.
zubka84 [21]

Answer:

The required solution is (0.128,13.82)

Step-by-step explanation:

Consider the provided system of equation.

-2.5x+y=13.5......(1)

12.25x - y=-12.25......(2)

We need to solve the system of equation by substitution method.

Consider the equation 1.

-2.5x+y=13.5

y=13.5+2.5x ......(3)

Substitute the value of y in equation 2.

12.25x - (13.5+2.5x)=-12.25

12.25x-13.5-2.5x=-12.25

9.75x-13.5=-12.25

9.75x=-12.25+13.5

9.75x=1.25

x\approx 0.128

Now substitute the value of x in equation 3.

y=13.5+2.5(0.128)

y\approx 13.82

Hence, the required solution is (0.128, 13.82)
