Tim answered all the questions on his math test but got 101010 answers wrong. He received 444 points for every correct answer, and there was no penalty for wrong answers. His score was 767676 points. Write an equation to determine the total number of questions (q)(q)left parenthesis, q, right parenthesis on Tim's math test.

Step-by-step explanation:

Let x represent the number of questions that Tim got right in the math test.

The number of questions that Tim got wrong in the math test is 10.

If the total number of questions on the math test is q, it means that

x + 10 = q

If he received 4 points for every correct answer and there was no penalty for wrong answers, it means that he received 0 point for a wrong answer. If

his score was 76 points, it means that

4x + 0 × 10 = 76

4x = 76

Therefore, the required equations are

x + 10 = q

4x = 76

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
