8 hours per day.
16 total hours.
32 30 minute sessions!
Thus 32 appointments in total.
I am going to assume these are points across the same line. (line segments)
If so, then jk + kl = jl
If jk is 6x and kl is 3x, we can solve for x.
6x + 3x = 27 (note we subbed 27 in for jl)
9x = 27 (divide both sides by 9 to leave on x on the left)
x = 3
CHECK! sub 3 in for x in the original problem.
6 (3) + 3 (3) = 27
18 + 9 = 27
Yes! It checks. x = 3
|-8|-2n=6n
The absolute value of a number is how far it is from a number line.
Answer:
3x + 9 = 21
Step-by-step explanation:
Let Henry's age be x
Mary's age = 9 + 3x
21 = 9 + 3x
Can also be written as 3x + 9 = 21
