First you move -15 over which makes it 7b=5b+12
then you move 5b over so then its 2b=12
divide b=6
The mean age is 29. Without rounding, it would be 29.4285714286

Answer:
24 hours
Step-by-step explanation:
Kristen = 8 hours
Kristen and Courtney = 6 hours
Courtney = x hours
in six hours kirsten can do 6/8 of the job
6/8 = 3/4
So kirsten is going to be doing 3/4 of the job
Courtney is only going to do 1/4 of the job
Number of hours it takes Courtney to do the job
6/x = 1/4
Cross product
6 * 4 = x * 1
24 = x
x = 24 hours
It will take Courtney 24 hours to type a 50-page paper on her own
Filling in the given values in point-slope equation
y = m(x -x₁) +y1
you have
y = 1(x -5) +3
This simplifies to ...
A. y = x - 2
Answer:
za=24
Step-by-step explanation:
supplementary angles add up to equal 180
180=7x+x+30+6
step 1 combine like terms
180=8x+36
step 2 subtract 36 from each side
144=8x
step 3 divide each side by 8
x=18
now we just plug in 18 to x in x+6
18+6=24
