Tim answered all the questions on his math yes but got 10 wrong. He received 4 points for every correct answer, and no penalty f

Pavlova-9 [17]

Answer: (a) 4x + 10(0) = 76

(b) 29questions

Step-by-step explanation: let the correct answer = x.

4points for correct answer each total 4xpoints

Since no penalty for wrong answers, his total points were 76points.

Equation: 4x = 76

x = 19. He scored 19 correct answers.

Total number of questions on the test = 19 correct answers + 10 wrong answers

<1 and <2 are supplementary angles. m <1 is 4y+7, and m<2 is 9y+4. Find m<2.

Yuliya22 [10]

Okay, so supplementary angles = 180 degrees.

Starting equation : 4y + 7 + 9y + 4 = 180

Combine like terms : 13y + 11 = 180

Subtract 11 from both sides : 13y = 169

Divide 13 from both sides : y = 13

Insert y value into original m<2 equation : 9(13) + 4

Solve : 121 degrees

If you want to check your work, all you have to do is insert y value into original m<1 equation and then add both m<1 and m<2. If they equal 180, your answer is correct.

4(13) + 7 = 59

59 + 121 = 180
