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

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 = $\frac{1}{4} x$ = $\frac{1}{4} *4=\frac{4}{4} =1$

Which of the following is the solution for 7 - 4x ≥ 35 ?

melamori03 [73]

There are no solutuons listed (says which of the following). My answer below should be in the list to choose from.

7 - 4x ≥ 35
subtract 7 from both sides

-4x ≥ 28
divide both sides by -4 AND change the direction of the inequality sign because we're dividing by a negative

x ≤ -7

CHECK:
7 - 4x ≥ 35
7 - 4(-7) ≥ 35
7 + 28 ≥ 35
35 ≥ 35

ANSWER: x ≤ -7

Hope this helps! :)
