So it took him 4/5 of an hour to paint 1/3
that means there is still 2/3 to go
so that means that he will have two times that time to paint the rest of the room
<u>4/5</u> = <u> ? </u>
1/3 2/3
using cross multiplication
(4/5)(2/3) = (1/3) (?)
8/15 = 1/3 ?
divide both sides by 1/3
so that will be 8/5
that means it will take 8/5 of an hour to complete the rest
or 12/5 total to do entire room
Hope this helps ;)

Answer:
3x + 7
Step-by-step explanation:
<u>Step 1: Distribute the plus</u>
(x + 4) + (2x + 3)
x + 4 + 2x + 3
<u>Step 2: Combine like terms</u>
x <u>+ 4</u> + 2x <u>+ 3</u>
<em>3x + 7</em>
<em />
Answer: 3x + 7
<u>If needed solve</u>
3x + 7 - 7 = 0 - 7
3x / 3 = -7 / 3
<em>x = -7/3</em>
Because b^6 is present in both terms, we can factor it out.
b^6(7 + 12)
Combine like terms.
b^6(19)
Rearrange.
19b^6 is the fully simplified form of the given expression.
