Algebra is a very important branch of math.
Algebra is a lot like arithmetic which means it follows all the rules of arithmetic, and it still uses the four main operations that arithmetic is built on.
In arithmetic, the only thing that was unknown was the answer to the problem. For example, 39 + 2 = 41. In algebra, we use a variable to represent the number. A variable is a letter that represents any number. The most common variable is "x".
Answer:
Step 1
Use the distributive property to multiply 22 by x-5x−5.
|2x-10|+11=17∣2x−10∣+11=17
Hint
Expand using distributive property.
Step 2
Subtract 1111 from both sides.
|2x-10|=17-11∣2x−10∣=17−11
Step 3
Subtract 1111 from 1717 to get 66.
|2x-10|=6∣2x−10∣=6
Hint
Subtract one term from another.
Step 4
Use the definition of absolute value.
2x-10=62x−10=6 2x-10=-62x−10=−6
Step 5
Add 1010 to both sides of the equation.
2x=162x=16 2x=42x=4
Step 6
Divide both sides by 22.
x=8x=8 x=2x=2
Solution
x=2x=2
x=8x=8

Answer/Step-by-step explanation:
Apply trigonometric bratio formula where applicable, to find the value of x in each case. Recall the acronym, SOHCAHTOA. This will help toe ash determine which ratio formula to use depending on the information given.
4. 
Opp = x
Hyp = 14
Therefore, apply SOH. Which is,
Multiply both sides by 14
(nearest tenth)
5. 
Adj = x
Hyp = 14
Therefore, apply CAH. Which is,
Multiply both sides by 14
(nearest tenth)
6.
Opp = x
Adj = 5.4
Therefore, apply TOA. Which is,
Multiply both sides by 5.4
(nearest tenth)
7. 
Opp = x
Adj = 33
Therefore, apply TOA. Which is,
Multiply both sides by 33
(nearest tenth)
