2 7/8 + 2 3/8= 4 10/8, which equals 5 2/8, which is also equal to 5 1/4
The answer to 3) is: x = ±7
Break down the problem into these 2 equations:
x/7 = 1 and -x/7 = 1
Then solve both equation and collect all solutions.

Answer:
x=-3
Step-by-step explanation:
If x=-3, then
x³+x²-2x+12=-27+9+6+12=-27+27=0
If this is true, then x+3 is a factor. So:
x³+x²-2x+12/x+3=x²-2x+4
So the factors of x³+x²-2x+12 are:
(x+3)(x²-2x+4)
((x²-2x+4) has no real roots)........
Answer:
9.71 miles
Step-by-step explanation:
total miles he ran = 6.19 + 3.1 = 9.29
Target = 19 miles
Goal for sunday = 19 - 9.29 = 9.71
Based on the definition of supplementary angles, the measure of both angles are: 80° and 100°.
<h3>What are Supplementary Angles?</h3>
The sum of angles that are supplementary to each other equals 180 degrees.
Let the measure of the supplementary angle be x.
The other angle will be: x + 20.
(x + 20) + x = 180
x + 20 + x = 180
2x + 20 = 180
2x = 180 - 20
2x = 160
x = 160/2
x = 80°
The other angle will be x + 20 = 80 + 20 = 100°.
The measure of the angles are: 80° and 100°.
