Answer:
472.5
Step-by-step explanation:
If you would like to know 80% of what number is 70, you can calculate this using the following steps:
80% of x is 70
80% * x = 70
80/100 * x = 70 /*100/80
x = 70 * 100 / 80
x = 87.5
Result: 80% of 87.5 is 70.
Answer: Choice A) All points with an x-value of 3 are located in Quadrant I.
We can show it is false through the use of a counter example. For instance, the point (3, -5) is not in quadrant 1, but rather in quadrant 4.
We would need to say "all points with x value 3 and positive y value" to ensure the point is in quadrant 1.
