4 * 7 = 28.
28 + (-10) = 18
Therefore, the answer is 18.
If you want to check this, you can subtract 7 from 18 four times.
Answer:
19 sit-ups per minute ;
95 sit-ups
Step-by-step explanation:
Given that :
Number of sit-ups done in 3 minutes = 57
The unit rate of sit-ups done can be obtained thus :
Total Number of sit-ups done / total time taken
= 57 sit-ups /3 minutes
= 19 sit-ups per minute
. Number of sit-ups that can be done in 5 minutes :
Unit Rate of sit-ups * number of minutes
19 sit-ups / minute * 5 minutes
= 95 (sit-ups / minute * minute)
= 95 sit-ups

Answer:
(x-4)^2 + (y-5)^2 = 20
Step-by-step explanation:
Rearrange the line equation of 5x - 2y + 6 = 0
So y = 5/2x +3
The y-intercept of the line equation is 3 as when x=0, y=3.
We know the Circle has the formula 
from the question but with the intercept, we can find the entire equation as the y-intercept is (0,3) so we can substitute it into the equation to find the full equations so:
This simplifies to:
= 
16 + 4 = 20 =
The answer is 20 so the equation of the circle is
