Answer:
3) 5/2
Step-by-step explanation:
5x - 2y = 20
(First, put it in slope intercept form: y = mx + b).
5x - 2y - 5x = 20 - 5x --> Subtracted 5x on both sides of the equation
- 2y = -5x + 20 --> Simplified
-2y/-2 = (-5x + 20)/-2 --> Divided by -2 on both sides
y = 2.5x - 10 --> Simplified
Since formula is, y = mx + b, then:
m (slope): 2.5
b (y-intercept): -10
Therefore, the answer is 3) 5/2

Answer:
260cm
Step-by-step explanation:
20x13=260
The answer would be -4 because if you do -4 times 2x then you would get -8x. Then if you did -4 times -3 you would get 12. (A negative times a negative equals a positive)

Remember that when posting questions here, you have to write the complete question in order to get a great and correct answer. Anyway, I found the complete question and is as follows:
<em>A grading machine can grade 96 multiple-choice tests in 2 minute. How long will it take the machine to grade 300 tests?</em>
<em />
So this problem can be used by using proportions. So we have that a grading machine can grade 96 multiple-choice tests in 2 minute. So we need to find the time (t) it takes the machine to grade 300 tests. So:
<em>Hence, it would take the machine 6.25 minutes, that is, 6 minutes and 15 seconds to grade 300 tests.</em>
