0.99 x 5 = $4.95
$4.95 is your answer
<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:
4
Step-by-step explanation:
you'd do 26-18 which will give the leftover money after paying for the two pizzas which equal 8
each soda costs 2 dollars so you would do 8 divided by 2 which is 4

D. 1/7
Step-by-step explanation:
There are seven cans of paint and only one of them are white, so there's a 1/7 of a chance she'll paint her bedroom white.
K, remember
(ab)/(cd)=(a/c)(b/d) or whatever
also
![(ab)^c=(a^c)(b^c)](https://tex.z-dn.net/?f=%28ab%29%5Ec%3D%28a%5Ec%29%28b%5Ec%29)
