Answer:
Direct variation
Step-by-step explanation:
It's not iverse because the line is curved so it's direct variation
Answer:the percent change in the puppy's weight= 275%
Step-by-step explanation:
Jillian's puppy Weight at 2 months =16 pounds
Jillian's puppy Weight at 8 months =60 pounds
percent change in the puppy's weight= change in weight / Old weight x 100
(60 pounds -16pounds ) / 16 x 100
44/16 x 100 = 275%
Answer:
1375
Step-by-step explanation:
Answer:
no solution
Step-by-step explanation:
2w + 7 = 2(w + 5) - 8
Distribute
2w+7 = 2w+10-8
Combine like terms
2w+7 = 2w+2
Subtract 2w from each side
7 = 2
This is never true so there is no solution
In the problem, the first equation should be represented like this base on the variable given in the problem:
20p + 9t = 44.4
with that equation, the second equation would is given by this formula, in response with the additional number of paperback and textbook
21p + 14t = 51
to get the system equation in getting the mass of each variable, you should subtract the two equation to simplified the formula.
20p + 9t = 44.4
- 21p + 14t = 51
-------------------------
p + 5t = 6.6 // this is the system equation that could be use in getting the mass of each object
