Please help me to get correct answer
valentinak56 [21]

Answer:

1. Because a right angle is 90 degrees, the answer to this is 90 - 65 = 25.

2. This question is similar to the last one, but this time the angle is 180 degrees total, so the answer is 180 - 55 = 125.

3. I'm fairly certain the lines here indicate that all three angles are the same. If all three angles make 180 degrees, the answer would be 180 / 3 = 60.

4. This is the same as in question 2. 180 - 135 = 45.

5. Again, because all three angles need to make up 180 degrees, we can just simply do 180 - (65 + 45) = 70.

6. With a quadrilateral, the angles add up to 360 degrees. We can do the same thing as in question 5 here. 360 - (70 + 95 + 55) = 140.

7. I don't remember exactly how to solve this but 55 degrees is correct because 55 + 55 + 70 = 180 which is the only possible value.

I haven't done this kind of stuff in a looooong time so I hope this suffices! :)

if the slopes of the lines in the system are equal and their y-intercepts are also equal, then the system is blank and blank
Tems11 [23]

Answer:

Step-by-step explanation:

same slope and same y-intercept = dependent system and represent the same line.

I'm not sure if those are words they want you use, as you didn't provide the answer choices.

Answer:

$82.5

Step-by-step explanation:

$82.5

Step-by-step explanation:

We can calculate it with a direct rule of 3. As it has a 30% off, the remaining price is the 70% and we want to know how much is the 100%

We use the formula of the direct rule of 3

x = 82.5

The original price of the stereo was $82.5
