X=2/3y because you want to know what roberts time is
Answer:
you can use it in architecture and construction
Step-by-step explanation:
say you are building a sloped roof. If you know the height of the roof and the length for it to cover, you can use the Pythagorean Theorem to find the diagonal length of the roof's slope. You can use this information to cut properly sized beams to support the roof, or calculate the area of the roof that you would need to shingle. I hope this helps!
<span>5[8 - (9x - 7)] + 6x = 0
5[8 -9x + 7] + 6x = 0
5(15 -9x) + 6x = 0
75 - 45x + 6x = 0
-39x = -75
39x = 75

30 bags of flour + 4 bags of sugar = 42.6 kg
each bag of sugar weighs 0.75 kg
each bag of flour weighs x kg = ?
If you would like to know what is the weight of each bag of flour, you can calculate this using the following steps:
30 * x + 4 * 0.75 kg = 42.6 kg
30 * x + 3 kg = 42.6 kg
30 * x = 42.6 kg - 3 kg
30 * x = 39.6 kg /30
x = 39.6 kg / 30
x = 1.32 kg
Result: Each bag of flour weighs 1.32 kg.
