Answer:
9Kg, 18Kg and 63 Kg
Step-by-step explanation:
Sum the parts of the ratio, 1 + 2 + 7 = 10 parts
Divide the weight of sand by 10 to find the value of one part of the ratio
90 Kg ÷ 10 = 9 Kg ← value of 1 part of the ratio, thus
2 parts = 2 × 9 Kg = 18 Kg
7 parts = 7 × 9 Kg = 63 Kg
Thus the weights of each bag are 9 Kg, 18 Kg and 63 Kg

Let's solve your inequality step-by-step.
5h−8h+12>18
Step 1: Simplify both sides of the inequality.
−3h+12>18
Step 2: Subtract 12 from both sides.
−3h+12−12>18−12
−3h>6
Step 3: Divide both sides by -3.
-3h/-3 > 6/-3
h<−2
