If Mercedes alone could paint the house in 8 hours, we would expect that both painting together would take less than 8 hours.
In 1 hour: Dorie would paint 1/12 of the house, while Mercedes would paint 1/8. This is a total of 1/12 + 1/8 = 5/24. If they can combine to paint 5/24 of the house in 1 hour, then the total time for the whole house would be
1 / (5/24) = 24/5 = 4.8 hours or 4 4/5 hours

Answer:
slope = 2
Step-by-step explanation:
Calculate the slope m using the slope formula
m = ![\frac{y_{2}-y_{1} }{x_{2}-x_{1} }](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D-y_%7B1%7D%20%20%7D%7Bx_%7B2%7D-x_%7B1%7D%20%20%7D)
with (x₁, y₁ ) = (- 3, 0) and (x₂, y₂ ) = (0, 6) ← 2 points on the line
m =

Answer: x≤6
Step-by-step explanation:
1. Simplify 5/3xto 5x/3.
5x/3≤10
2.Multiply both sides by 3.
5x≤10×35x
3. Simplify 10×3 to 30.
5x≤30
4. Divide both sides by 5.
x≤30/5x
5. Simplify 30/5 to 6.
x≤6
Step-by-step explanation:
log2(3x) + log2(4) = 4
log2(3x × 4) = 4
log2(12x) = 4
12x = 2⁴
12x = 16
x = 16/12
= 4/3
