.) Paco and Ping went shopping for erasers, e, and markers, m. Paco bought 5 erasers and 7 markers for $4.05. Ping bought 10 erasers and 3 markers for $3.15. Their purchases can be modeled by the system of equations. *Solve the system of equations for e and m.
*Show your work.
5e+7m=4.05
10e+3m=3.15
Explain what each numerical solution represents in the context of this word problem.

yeah and

step-by-step explanation:

you know what it isnt great cheating

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

the k side
