Answer:
Step-by-step explanation:
On number line what you do is you plot the point of 7/6 then because it is equal you color in the circle. Since the inequality is less than you draw you r line to the left
Answer:
45
Step-by-step explanation:
If you write it out it will look like this, 2x+45+x=180
3x+45=180
3x+45=180
-45 -45
3x=135
/3 /3
x=45
Answer:
$700
Step-by-step explanation:
First you find what 7% of $2000 is,
(2000/100)7=140
$140 per year interest, over the course of five years that would be $700
140)5
Answer:
x=22
Step-by-step explanation:
To solve, use an important geometry theorem.
- The exterior angle of a triangle is equal to the sum of the two opposite interior angles.
Know this theorem, write 6x-7 = 103-x+2x and solve for x.
6x-7=103-x+2x
6x-7=103+x
5x-7=103
5x=110
x=22
