Hope this help! I’m sure this is right!
Answer:
133
Step-by-step explanation:
The two angles add to a straight line
PQR + RQS = PQS
3x-5 + x+1 = 180
Combine like terms
4x -4 =180
Add 4 to each side
4x -4+4 = 180+4
4x =184
Divide each side by 4
4x/4 =184/4
x =46
We want to find PQR
PQR = 3x-5
= 3*46 - 5
= 138 -5
= 133
Answer:
x = -1 and x = 1
Step-by-step explanation:
<em>Excluded values</em> are values that will make the denominator of a fraction equal to 0.
The fraction is (x+1)/(x² - 1)
x² - 1 = 0
x² = 1
x = ±1
The excluded values are x = -1 and x = 1.
Answer:
x = 19
Step-by-step explanation:
x +(-14)= 5
we start by multiplying the + and the - in the bracket which gives you -
posiyive x negative = negative
x - 14 = 5
the -14 crosses the equal sign and becomes +14
x=5 +14
x = 19
