Think about converting 48% to an equivalent fraction in reduced form. If the denominator is 25, what is the numerator?

bulgar [2K]

Answer:

the numerator is 12

Step-by-step explanation:

since 48 is a percent, it would be put as 48/100 as a fraction. since both the numerator and denominator are divisible by 4, you can reduce the fraction into 12/25. Since the question is asking what the numerator was when the denominator was 25, the answer is 12.

Solve the system of equations using the substitution method. y=2+1/4x,

skelet666 [1.2K]

Answer: (4,3)

Step-by-step explanation:

1. In this method you must solve one of the equation for one of the variables and substitute it into the other equation to find the other variable. Then, substitute the value of that variable into one of the original equation to obtain the value of the other one.

2 You have that:

$y=2+1/4x$

3. Then, you can substitute it into the other equation and solve for x:

$3x-5(2+1/4x)=-3\\3x-10-5/4x=-3\\7/4x=7\\x=4$

4. Now you can obtain y:

$y=2+1/4x$

$y=2+1/4(4)\\y=3$

5. The answer is:

(4,3)
