ALGEBRA 1 Exercises, find the solution set of the sentence and check. Do exercises 5 to 12 :).

1. 3m = 15.
2. 9t=36.
3. 15x= -45.
4. 23z=-46.
5. – 77 = 11k.
6. 4x=9.
7. -5 = 2y.
8. 9a=- 6.
9. – 13a= 65.
10. -8k = 8.8.
11. -5m =-35.
12. 2x= -1/9

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
