One number is 1/4 of another number. The sum of the two numbers is 5. Find the two numbers. Use a comma to separate your answer

masha68 [24]

Answer: 1, 4

Step-by-step explanation:

Number #1 = x
Number #2 = $\frac{1}{4} x$

$\frac{1}{4} x+x=5\\\\\frac{1}{4} x+\frac{4}{4} x=5\\\\\frac{5}{4} x=5\\\\5x=4*5\\5x=20\\x=4$

Number #1 = x = 4
Number #2 = $\frac{1}{4} x$ = $\frac{1}{4} *4=\frac{4}{4} =1$

-10x+4-4=52-4

-10x=48

Divide -10 on both sides

-10x/-10=48/-10

x=-4.8

Write the expression "N is the same as 6 reduced by 2" as a number sentence.

Anton [14]

Answer:

N=6-2

Step-by-step explanation:

When speaking the language of math, "the same as" just means equal to. On the left side of the equal sign, you have your variable, and on the right is the rest of the equation. 6 reduced by 2 is the same thing as 6-2
