Answer:
x=13
Step-by-step explanation:
We want to divide whole sand into scoops, so we have to divide 4/5 by 1/20. Lets do this

We know that if we want to divide 2 fraction we can multiply first by inverse of second fraction instead of dividing.,so:


scoops - its our result.
Answer:
1: n > -75
2: n < -12
Step-by-step explanation:
1: n/-3 - 8 < 17
n/-3 (- 8 + 8) < 17 + 8
n/-3 < 25
n/-3(-3) < 25(-3)
n < -75
n > -75 (switch symbol when you divide or multiply by a negative number)
2: n/-2 + 11 > 17
n/-2 (+ 11 - 11) > 17 - 11
n/-2 > 6
n/-2(-2) > 6(-2)
n > -12
n < -12 (switch symbol when you divide or multiply by a negative number)
It is but it needs to be rearranged to x^2-2x+30
