Question

June was thinking of a number. June doubles it and adds 4.4 to get an answer of 67.9. Form an equation with x from the information.

Answer 1

Answer:

the number she was thinking of was

$31.75$

Step-by-step explanation:

let the number be x

according to question;

• 2x + 4.4 = 67.9
• 2x = 67.9 - 4.4
• 2x = 63.5
• x = 63.50 ÷ 2
• x = 31.75

the required number is x = 31.75

Answer 2

$2x + 4.4 = 67.9$

Step-by-step explanation:

Hey!

So since we know that a number was doubled, and that x represents the unknown number, we can come up with the first part of the equation: 2x.

Since we also know that 4.4 was added, the equation now becomes 2x+4.4

With the end result of the whole thing being 67.9, the equation now because 2x+4.4=67.9
