Answer:
16 hours
Step-by-step explanation:
let t be time, n the number of computers and w the number of workers, then
t = 
← k is the constant of variation
To find k use the condition n = 30, w = 6 and t = 10 , then
10 = 
( multiply both sides by 6 )
60 = 30k ( divide both sides by 30 )
2 = k
t = 
← equation of variation
When w = 5 and n = 40 , then
t = 
= 
= 16 hours
Answer:
icoles
Step-by-step explanation:
Find the cost of all the items together.
4.99 + 0.46 + 0.89 = $6.34
Find the sales tax.
6% = 0.06
6.34 * 0.06 = 0.3804
Add.
6.34 + 0.3804 = 6.7204
Round.
6.7204 = 6.72
He spent approximately $6.72
Hope This Helped! Good Luck!
Jayla= x
keisha= x+ 3
melanie= x + 6
to solve:
42= x + x + 3 + x + 6
42= 3x + 9
-9 -9
33=3x
———-
3
x=11
therefore
jayla is 11
keisha is 14
melanie is 17
