If each gallon is $2.85, you multiply $2.85 by however many gallons you buy. so, 1.6 x $2.85 = $4.56.
To solve for b, you need to isolate/get the variable "b" by itself in the equation:
A = h(a + b) Divide h on both sides

Subtract a on both sides to get "b" by itself


One way:

(360 degrees in a circle which is what a pie chart is)
or

x 360
which is

= 144⁰ angle
4,6,8 are being counted by twos so the next one is 10
4•3= 12, 6+3=9, 8-3=6, the next operation I assume would be division so 10/3= 3.34
