Answer:
$2.25
Step-by-step explanation:
Let "b" be the price of 1 brownie and "c" the price of 1 cookie.
At a bake sale, a student spent $11.00 buying 3 brownies and 5 cookies. Symbolicaly,
3 b + 5 c = 11.00 [1]
His friend spent $3.95 buying 1 brownie and 2 cookies. Symbolicaly,
1 b + 2 c = 3.95
b = 3.95 - 2c [2]
If we replace [2] in [1], we get
3 (3.95 - 2c) + 5 c = 11.00
11.85 - 6c + 5c = 11.00
c = 0.85
If we replace c = 0.85 in [2], we get
b = 3.95 - 2 (0.85) = 2.25

Answer:
x= -10
Step-by-step explanation:
The equation is y2-y1 over x2 over x1 so
1-(-2) over -9-(x)=3
1+2=3 over -9-(x)
3/-9-x times -9-x = 3 times -9-x
3=3(-9-x)
3=-27-3x
3+27=-3x
30= -3x
-10= 3x
hope it helps man!!! :)
