I really don't know try it and if you don't get it bring it to school and then ask the teacher
Answer:
x = 48
Step-by-step explanation:
first you would add them together and set it equal to 180( because a straight line is 180 degrees): 3x - 12 + x = 180
Then you add like terms( the x's): 4x - 12 = 180
now add 12 to both sides: 4x = 192
now divide by 4 on both sides x = 48
hope this helps! : )
Answer:
The last choice: 68/5 - 22/5 = 9 1/5
Step-by-step explanation:
Solve each problem:
9 3/7 = 10 3/7
The fractions are the same so look at the whole numbers.
Does 9 equal 10? No, it doesn't so this is a false statement.
332/4 = 1/83
Simplify 332/4:
332/4 = 83/1
83 does not equal 1/83 so this is a false statement.
37/5 = 5 2/5
Convert the improper fraction into a mixed number:
7 2/5 = 5 2/5
These numbers do not equal each other so this is a false.
68/5 - 22/5 = 9 1/5
Subtract the numerators on the left side of the equation:
46/5 = 9 1/5
Convert the improper fraction into a mixed number:
9 1/5 = 9 1/5
These numbers equal each other so this is a true statement!
If you would like to write x = 1/3 * y in general form, you can do this using the following steps:
<span>The general form of the equation is: </span>ax + by + c = 0.
x = 1/3 * y
x - 1/3 * y = 0
The correct result would be <span>x - 1/3 * y = 0.</span>
