Answer:
x÷4≤15
Step-by-step explanation:
the quotient of a number (x) and 4: x÷4
the phrase "at most" means ≤, less than or equal to
so if we put the parts together, we get x÷4≤15
Answer: y ≤ 10
Step-by-step explanation:
16 ≥ 2y -4
Add 4 to both sides
16 + 4 ≥ 2y - 4 + 4
20 ≥ 2y
divide through by 2
20/2 ≥ 2y / 2
10 ≥ y
Therefore :
y ≤ 10
Answer: You have nothing to answer, but i will take the points
Step-by-step explanation:
It will take them 4.24 hours together to paint the area together
Step-by-step explanation:
If Emily takes eight hours to paint the area then she will paint 1/8 of the house in one hour
Similarly, if Mike can paint the same area in 9 hours, then he will paint 1/9 of the same area
Let x be the number of hours in which they will together paint the area.
If x hours are taken by them to paint the area then 1/x of the area will be painted in one hour
So,

It will take them 4.24 hours together to paint the area together
