5(20) + 4y = 216
100 + 4y = 216
4y = 216 - 100
4y = 116
y = 116/4
y = 29.....so they sold 29 four-dollar yogurts + 20 five-dollar yogurts....for a total of 49 yogurts sold <==
Use the subusitution method for r
g(4)=25-3(4)
g(4)= 25-12
g(4)= 13
Answer is g(4)= 13
Answer:
Done below!
Step-by-step explanation:
(x - root)
(x - 2)(x - (-1))(x - (-5)) = (x - 2)(x + 1)(x + 5)

Solve for a.
6 = a / 4 + 2
Subtract 2 from both sides.
4 = a / 4
Multiply both sides by 4.
16 = a
