Answer: 2.66 hours
Step-by-step explanation:
Shawana can paint a fence in 8hours which means in one hour she can paint 1/8 of a fence.
Kevin can paint the same fence in 4 hours, so in one hour he can paint 1/4 of the fence.
Together in 1 hour they can paint 1/8 + 1/4 = 3/8
Total hours for painting is 3/8 or 2.66 hours

Step-by-step explanation:
The answer is 12 inches
Answer:
11 degrees.
Step-by-step explanation:
<em>"Angles T and U are a linear pair. Angle U measure (9x+6) and Angle T measures(6x+9). What is the value of x, in degrees?"</em>
We know that a linear pair MUST add up to 180 degrees, therefore (9x+6)+(6x+9)= 180
Now for some algebra-
(9x+6)+(6x+9)= 180
6 and nine can both be divided by 3, so we will do that for simplicity:
((9x+6)+(6x+9)= 180)/3=
(3x+2)+(2x+3)=60
We will now separate the parenthesis, as they serve no purpose anymore.
(3x+2)+(2x+3)=60
3x+2+2x+3=60
Combine terms
5x+5=60
Take away the 5 to isolate the variables
5x+5=60
-5
5x=55
Divide by 5
5x=55
/5
x=11
The value of x is 11 degrees.
