Step-by-step explanation:
hope this is right...
30 - 5*4 +2 = 12
30 - 20 +2 = 12
10+2 = 12
12 = 12
she bought 10 pencils and 5 erasers
Let x represent the number of pencils and y represent the number of erasers.
Gabby wants to spend exactly $2.00 on pencils and erasers, hence:
0.15x - 0.1y = 2 (1)
Therefore x = 10 and y = 5
Therefore she bought 10 pencils and 5 erasers.

Answer:
1. The angles of a triangle added up all together is 180. So, we can solve a as an equation!
36+57+a=180.
From this, we can figure out a:
a=87
2. The same goes for this one, just a bit different. We write our equation like this:
3x+90=180
we solve this:
3x=90
we divide both sides by 3 and get:
x=30
