Answer:
Step-by-step explanation:
Let E = Erasers and P = Pencils
4E + 2 P = $16…(1)
3E + 1P = $10.50…(2)
Multiply (2) by 2 to make Pencils in (1) and (2) equal.
6E + 2P = $21…(3)
Subtract (3) from (1) to eliminate P
2E = $5 => Erasers = $2.50 each
Substitute this value for Erasers into (3)
6 * $2.50 + 2P = $21
2P = $21 - $15 = $6 => Pencils = $3
Therefore 5 Erasers + 3 Pencils cost
5 * $2.50 + 3 * $3 = $12.50 + $9 = $21.50
Answer: The answer is B. Hope this helps :)

Answer:
A = 29
Step-by-step explanation:
a triangle is equal to 180 so the bottom triangle you add 34 + 26 = 60 --> 180-60 = 120 ---> the triangle on top is 120 + 31 = 151 -----> 180-151 = 29
Answer:
Undefined slope.
Step-by-step explanation:
The formula should be y2 - y1 over x2 - x1
Points ( 20,-16 ) and ( 19, -16 )
So ( -16 - ( -16 ) ) over ( 19 - 20 )
0 over -1
The slope is 0. Undefined.
