PLEASE ANSWER ASAP! I'M GIVING A LOT OF POINTS!

nikdorinn [45]

In this question you need to isolate j. First you multiply 11 on both sides to make 3 + j not a fraction anymore.

3 + j = 22.
Then you isolate j by subtracting 3 on both sides since you must cancel the 3's out to isolate j. Then you get an answer of j = 19

1) ACT Prep: Linear Pair angles have measures (6x -9)°and (9x-6)° 1.

iris [78.8K]

The measure of angles are 69 degree and 111 degree

Solution:

Given is linear pair angles

The measure of angles are: (6x - 9) degrees and (9x - 6) degrees

A linear pair of angles is formed when two lines intersect.

The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.

Therefore,

$(6x - 9) + (9x - 6) = 180\\\\\text{Remove the parenthesis and solve}\\\\6x - 9 + 9x - 6 = 180\\\\\text{Combine the like terms}\\\\6x + 9x - 15 = 180\\\\15x - 15 = 180\\\\\text{Move the constants to right side}\\\\15x = 180 + 15\\\\15x = 195\\\\x = 13$

Thus the measure of angles are:

$(6x - 9) \text{ degrees } = 6(13) - 9 = 78-9 = 69 \text{ degrees }\\\\(9x - 6) \text{ degrees } = 9(13) - 6 = 117 - 6 = 111 \text{ degrees }$

Thus measure of angles are 69 degree and 111 degree
