Answer is B) 13L.
Explanation:
We can calculate the number of liters of cleaning solution required to clean up a surface with the given area by simple method of proportion.
If 25m^2 area requires 5L of cleaning solution,
then let x be the number of liters required for cleaning a 65m^2 area.
We can write it as:
25 / 65 = 5 /x
x = (5 x 65) / 25 = 325/25 = 13
So, 13 litres of cleaning solution is required to clean a surface with 65m^2 area.
for this question, it ask you to draw out.
j + 6 ≥ 7
j ≥ 7 - 6
j ≥ 1
How to draw it:
1. draw a Solid point on the number"1".
2. draw a small vertical line on the top of the point.
3. draw a long horizontal line to number "1" 's right side, and add an arrow in the end of the line.
4w-7k=28
-4w -4w
-7k=-4w + 28
/-7 /-7
k=0.57 + 4
