Answer:
x = 11
Step-by-step explanation:
Equation:
(5x+1) + (12x-8) = 180
You are doing this because both sides on a straight line add up to 180 degrees. The two angles would add up to 180 degrees since they are on the one side of the line.
Simplifying:
(5x+12x) + (1-8) = 180
Add your common variables together; keep in mind that variables are placed before numbers.
Adding:
17x-7 = 180
Process:
To do this, you are going to simply do the opposite operation for the number without the variable on both sides of the equal sign.
17x - 7 = 180
+ 7 + 7
------------------
17x = 187
----- ------
17 17
x = 11
You divided by 17 on both sides because you needed to get the x variable by itself. Hope this helped! :)
Answer:
To find a baseball pitcher's earned run average you can use the formula EI 9r
To find a baseball pitcher's earned run average (ERA), you can use the formula Ei=9r, where E represents ERA, i represents number of innings pitched, and r represents number of earned runs allowed.

Answer:
first problem is the second one, second problem is the third one
Step-by-step explanation:
for the first problem, just write out the equation (x-1)(x-2)(x+2)(x+3) and multiply them to get the answer
for the second problem, just factor it and you should get 3x(x+2)(x+3)
Answer:
The HCF of two or more numbers is the highest common factor of the given numbers. It is found by multiplying the common prime factors of the given numbers.
To get the Least Common Multiple (LCM) of 1820 and 3510 we need to factor each value first and then we choose all the factors which appear in any column and multiply them:
1820: 2 2 5 7 13
3510: 2 3 3 3 5 13
LCM: 2 2 3 3 3 5 7 13
The Least Common Multiple (LCM) is: 2 x 2 x 3 x 3 x 3 x 5 x 7 x 13 = 49140
