Answer:
150
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles
<1 + <2 = <3
3x+11 + 3x+19 = 7x+10
Combine like terms
6x+30 = 7x+10
Subtract 6x from each side
6x -6x+30 = 7x-6x+10
30 = x+10
Subtract 10 from each side
30-10 = x+10-10
20 =x
We need to find angle 3
<3 = 7x+10
= 7(20)+10
= 140+10
= 150
Answer:.
x greater than or equal to -8
Step-by-step explanation:
x+22-13x≥118
Collect like terms
x-13x≥118-22
-12x≥96
Divide both sides by -12
-12x/12≥96/-12
x≥96/-12
x≥-8
The answer is x greater than or equal to -8
Answer:
45
Step-by-step explanation:
F^-1(x)= x/9 + 1/3
To find this, just interchange the variables and solve for y.
y=9x-3
x=9y-3
x+3=9y
divide by nine
