So we want to know what a full box is. We have the weight of half a box. So we can use the formula: (2 x 3/5) and you want to know the outcome of four full boxes. So (2x3/5)4
Or: 6/5 x 4
And the answer is 24/5. But if you want to simplify it, it’s 4 4/5
Answer:
angles r 50°&40°
Step-by-step explanation:
- 2p+p+15=90°
- 3p=90°-15°
- 3p=75°
- p=75°/3
- p=25°
2p=2×25=50°
p+15=25+15=40°

Y = -21 1/6
Answer:
-12, -1, 0, 2, 15, 18.
Step-by-step explanation:
minus(-) are always less than 0
Let us assume that x kg of 30% salt solution is mixed with (200-x) kg of 40% salt solution in order to obtain 200 kg of 37% salt solution.
We can set up a linear equation in terms of x by setting amount of total salt before mixing and after mixing equal to each other.
Therefore, 60 kg of 30% salt solution should be mixed with 140 kg of 40% solution.
