Answer:

Step-by-step explanation:
Start by making a common denominator. In this case, it would be 12.
Multiply -1/3 by 4 to get -4/12
Multiply -9/4 by 3 to get -27/12
Then subtract
-
- (-
) =23/12
You can also visualize this on a number line. Once you've made the denominator the same, start at -4/12 and move 27 units to the left to land on 23/12.

Step-by-step explanation:

Answer:
95°
Step-by-step explanation:
1) the angles one and four are equivalent so you can equate the expressions given for their values and get:
3x+10=4x-15
if you combine like terms you will get that x = 25
2) plug in your x value into one of the expressions to get the value for that angle and you should get 85.
3) because angles 1 and 7 are corresponding exterior angles we know that they add up to 180°. so we can make the following equation:
x+85°=180°
4) solve for x and you have your answer
