Answer:
x=2, z=62
Step-by-step explanation:
Since (14x+34) and (11x+96) are linear angles, their angle measures must add to 180 degrees. We can thus set up this equation:
14x+34+11x+96=180
25x+130=180
25x=50
x=2
Since z and (14x+34) are vertically opposite angles, their values must be equal. Thus:
z=14x+34=14(2)+34=28+34=62
Answer:
2.25
Step-by-step explanation:
Answer:
V=πr^2(h/3)
Step-by-step explanation:
V=π6^2(8/3)
So we need to solve:
3ˣ⁻¹ = 9ˣ⁺²
To do this, we need to have the same base for both sides of the equation.
So let's go with the base of 3.
3² = 9
3ˣ⁻¹ = (3²)ˣ⁺²
3ˣ⁻¹ = 3²ˣ⁺⁴
Since the bases are the same now, we need to get rid of them and we would get:
x - 1 = 2x + 4
Subtract both sides by 2x:
-x - 1 = 4
Add 1 to both sides:
-x = 5
Divide both sides by -1:
x = -5
