<span>3x – y = 18
We start by plugging in 27 for y. The goal is to isolate x by itself to solve for x.
3x - 27 = 18
Then we add 27 to both sides of the equation
3x = 45
Lastly, we divide both sides by 3 to finally isolate x by itself and solve.
x = 15</span>
It's already rounded to the nearest tenth, so it's still the same.
Answer:
6
Step-by-step explanation:
(whole secant) x (external part) = (tangent)^2
(5+4) * 4 = x^2
9*4 = x^2
36 = x^2
Taking the square root of each side
6 =x
Answer:
Positive correlation
Step-by-step explanation:
Although the points are less to be sure about the association, but the positive slope of the line of best fit indicates positive association
Answer:
Step-by-step explanation:
PQS and RQS are supplementary
PQS +68=180
PQS =112
x+ 112+TSQ=180
4x=3x+TSQ
TSQ=x which means
2x+112=180
2x=68
x=34
