You can use liters, cups, etc i would suggest kiters
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:
-10=x
Step-by-step explanation:
9x-1=10x+9
9x-10×=9+1
-x=10
x=-10
Answer: a= (4x-1)(6x+9)
Step-by-step explanation:
area= length x width
bro doesnt it say the correct answer right there??
