Apply distributive property
-9-9x+4=-5
Combine like terms
-5-9x=-5
Add 5 to both sides
-9x=0
Divide both sides by -9
x=0
Final answer: x=0
Answer:
the answer is 45 Lol.Hope that helps
A number raised to an exponent is that number multiplied by itself that number of times.
17^3 = 17 x 17 x 17 = 4913
The answer is B.
Answer:
x = 7
Step-by-step explanation:
4x - 2(x + 4) = 22
Distribute:
4x - 2x - 8 = 22
Combine like terms:
2x - 8 = 22
Simplify and solve:
2x = 14
x = 7
To solve this (assuming that you are using a graphing calculator of some sort) you have to first isolate x since that is what you are solving for. First, you multiply both sides by x to get x on the numerator to make it easier to solve. This would look something like this: x(Cos 55)=13
Then, to isolate x, you divide both sides by cos 55 leaving you with this: x= 13/cos55.
Then, you type 13/cos 55 (make sure your calculator is in degrees) and you get 22.66 (rounded to nearest hundredth)
