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
Answer:
1.33
Step-by-step explanation:
y2-y1/x2-x1
=11+1/-3-6
=12/-9
=-4/3
=1.33
PINEAPPLE DOES NOT BELONG ON PIZZA
Answer:
m= 6/-5
Step-by-step explanation:
m= y2-y1/x2-x1
m= 6-(-6)/-18-(-8)
m= 12/-10
m= 6/-5
Find -4 on the number line.
Go to the right 6 place values (+6)
You will find your answer
-4 (+6) = 2
2 is your answer
hope this helps
