Answer:
Product means to multiply.
No more than 30 is basically it can be 30 OR less nothing more.
k(-5) ≤ 30
Thats your inequality.
Solution is easy.
-5k ≤ 30
Divide -5
k ≥ 6
k ≥ 6 since when you divide or multiply by a negative number the inequality is flipped.
k≥ 6 is your solution .

10/12 = (3x+2)/(5x-0.4)
10(5x-0.4) = 12(3x+2)
50x - 4 = 36x + 24
50x - 36x = 24 + 4
14x = 28
x = 28/14
x = 2
QS = 3x + 2 = 3*2 + 2 = 6 + 2 = 8
SR = 5x - 0.4 = 5*2 - 0.4 = 10 - 0.4 = 9.6
Answer is QS=8, SR=9.6

I got 180 because the triangle is 180
The weight of A is 75kg.
<h3>How to calculate the weight?</h3>
Total weight of A + B + C = 84 x 3 = 252kg
Total weight of A + B + C + D = 80 x 4 =.320 kg
Weight of D = 320 - 252 = 68 kg
Given, E = D + 3 = (68 + 3) kg = 71 kg
Total weight of B + C + D + E = (79 x 4) = 316 kg
Weight of B + C = 316 kg - 71 kg - 68 kg = 177 kg
Weight of A only will be:
= 320 kg - 177 kg - 68 kg
= 75 kg
