You could solve it with these two steps:
#1). Subtract 6 from each side of the equation.
and then
#2). Divide each side by 7.
If you'll do that, the solution will be right there on the paper in front of you.
It'll begin with "x =", and right after that will be the value of 'x'.
Answer:

Step-by-step explanation:
<u>Step 1: Subtract 21 from both sides</u>



<u>Step 2: Divide 8 from both sides</u>



Answer: 
R=6 & s=1/4
Just plug that in to the equation.
6+1/4 +14(1/4)
6.25 +3.5
9.75 or 39/4
Order them from smallest to largest:
21, 24, 25, 26, 26, 31
mean: 25.5
add all the numbers up and divide them by 6.
median: 25.5
the number in between 25 & 26.
mode: 26
there are two 26’s in the pattern.
range: 21-31
Answer:
y=-2x+80
Step-by-step explanation:
40=(-2*20)+b
40=-40+b
80=b
y=(-2*20)+80
y=-40+80
y=40
