Answer:
Step-by-step explanation:
Let x represent the number of multiple choice questions in the science test.
Let y represent the number of short answer questions in the science test.
Each multiple choice question is worth 2 points and each short answer is worth 5 points. This means that x multiple choice questions would be worth 2x points and y short answer questions would be worth 5y points
Therefore, an equation to represent the total points possible for the test would be
2x + 5y
Step-by-step explanation:
Given
- 4( 3x - 5 ) > - 28
Dividing both sides by - 4 we get
3x - 5 > 7
Adding 5 on both sides we get
3x - 5 + 5 > 7 + 5
3x > 12
Dividing both sides by 3 we get
x > 4
equation would be 23 plus 9 equals 32 or p, the number of cans she bought
7.1 and 7.5 because any integer is a rational number
