The equation 8 − 4x = 0 has real solution(s).

The equation has exactly 1 real solution.

You can find this by solving it.

8 - 4x = 0 > add 4x to both sides

8 = 4x > divide both sides by 4

2 = x

You can see there is only 1 and therefore it has one solution.

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
