8 0

Answer:

There is no value of x that will make this true

Step-by-step explanation:

x+4=x+8

Subtract x from each side

x-x+4=x-x+8

4 = 8

This is never true so there is no solution

How to write an improper fraction as a mixed number or whole number?
qaws [65]
See how many times the denominator goes into the numerator. For example, with 24/8, 8 goes into 24 three times, so 24/8 is 3. If I had 25/8, then it would be 3 1/8 because you have one left over after you divide the 8 into 25.

\A and \B are supplementary angles. If m\A= (3x – 23) and m
mrs_skeptik [129]

2 supplementary angles when added together need to equal 180 degrees.

Add:

3x-23 + 2x-12 = 180

Simplify:

5x -35 = 180

Add 35 to both sides:

5x = 215

Divide both sides by 5:

X = 43

Now replace x with 43 in the equation for angle b:

2(43) -12 = 86-12 = 74 degrees

Angle B = 74 degrees
