Write an equation to represent the number puzzle. Use x as the
variable. Then find the solution using guess-check-and-improve.
5 times a number, plus 1, is equal to 9 added to 3 times the number.
What is the number?
a. 5x + 1 = 9 + 3x, 4 c. 5x + 1 = 9 + 3x, 3
b. 5x − 1 = 9 + 3x, 5 d. 5x + 1 = 9 + 3x, 4.5

It is A

Step-by-step explanation:

Equation: 5x+1=9+3x

5x+1=9+3x

     -1 -1

5x=8+3x

-3x     -3x

Step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
