D -2, 4 is in the second quadrant because the -x brings it to the left side and the positive 4 puts it in the upper of the left side which is the second quadrant
Answer:
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
Answer:
7/15
Step-by-step explanation:
Yooooo thank you so much this is great I need this
We can set up the following equation:
4x + 4(5) = 54
X representa the cost of a salad, and the 4(5) shows how each time she left a tip of 5.
Now we solve:
4x + 20 = 54
Subtract 20 from each side:
4x = 34
Now divide by 4
X = 8.5
So the cost of each salad is $8.50
I hope this Helps!
