Write a real word problem that cold be solved by using the equation 3x- 25= 125

If we have a problem,

In a school there are 125 girls which is 25 less than 3 times of the number of boys how many boys are there ?

Let x be the number of boys,

So, the number of girls = 3 × number of boys - 25

= 3x - 25,

∵ Number of girls = 125

⇒ 3x - 25 = 125

Hence, the above real word problem could be solved by the given equation.

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
