15 % on her next free throws because a percent is always out of a 100. leftover is 30 half of 30 is 15 do it is 15%
Answer:
<u>420 names were read</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Rate of names read per minute at the graduation ceremony = 5
2. If the names had been read at the rate of seven names per minute, the ceremony would have taken 24 minutes less. How many names were read?
x = Number of minutes it takes to read the names at the rate of seven names per minute
x + 24 = Number of minutes it takes to read the names at the rate of five names per minute
Solving for x:
5 * (x + 24) = 7x
5x + 120 = 7x
5x - 7x = -120 (Subtracting 120 and 7x at both sides)
-2x = -120
x = -120/-2
x = 60 ⇒ 7x = 420
<u>420 names were read</u>
Answer:
You use the manipulation of numbers in <u><em>algebra/mathematics.</em></u>
Answer:

Step-by-step explanation:
The function seems to increase at a constant rate of 3 units. This means that the equation that satisfies these points could be that of a straight line.
We use the first two points to find the slope of the line.
(0, -10)
(1, -7)
(2, -4)
The equation of a line is:

Where m is the slope of the line and b is the cutoff point with the y axis.
To find the slope of a line we use the following equation:


So:

The cut point (b) is found by replacing in the previous equation, any of the three points provided and clearing b.


Now we can write the equation of the line sought.

You can verify that the three points provided belong to this equation.
