Answer:
Thats correct.
Step-by-step explanation:
<span>Assuming that 2 people who will repair a refrigerator equally fast will do it twice as fast when working together:
Jannete repairs 1/60 refrigerator per minute.
Lisa repairs 1/40 refrigerator per minute.
Togheter they repair 1/60+1/40= 1/60 + 1,5/60 = 2,5/60=5/120=1/24 refrigerator per minute
thus it will take them 24 minutes</span>
Answer:
Yes
Step-by-step explanation:
The way the equation is written in point-slope form is:
The way we write an equation in slope-intercept form is:
We can change point-slope form to slope-intercept form by first distributing the m and then adding y1 to both sides of the equation. When we do this we will get:
where 
which is now in slope intercept form.
Answer:
$50 and
$30
Step-by-step explanation:
Question 1. Principal = $500
Rate = 5%
Time = 2yesrs
Interest = PRT /100
= 500 x 5 x 2 /100
= 5000/100
= $50
Interest = PRT/100
Principal P =$500
Rate = 3%
Time = 2 years
Therefore, interest =
500 x 3 x 2 /100
= 3000/100
= $30
4a^2-2ab-5b^2 :) that is simplified
