2x-6=14 2x=20
a)x=10
-5x5=40 -5x=35
B)x=-7
12x+240=24 12x=-216
C) x=-18
M < PQS + m < RQS = 180° because they are supplementary angles.
Therefore:
(3x + 3) + (x + 19) = 180
3x — 3 + x + 19 = 180
4x + 16 = 180
Subtract 16 from both sides
4x — 16 = 180 — 16
4x = 164
Divide both sides by 4:
4x/4 = 164/4
x = 41
Therefore, the correct answer is x = 41
Answer:
-3
Step-by-step explanation:
y = -3x
This is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
The slope is -3 and the y intercept is 0
Answer:
Step-by-step explanation:
16n^2-25=0
16n^2=25
n^2=25/16
n=+-5/4
