1 pizza should cost $5.65
Pizza is $5.65 then bottle of coke is $2.45
3 pizzas and coke: ($5.65*3) + $2.45 = $19.4
I solved this by setting up and solving a system of linear equations:
Variables: p = pizza, c = coke
p = c+3.2
3p+c = 19.4
Solve by substitution
3(c+3.2) + c = 19.4
4c+9.6 = 19.4
c = 2.45
Re-plug in:
p = 2.45+3.2
p = 5.65
V...volume
B...Base
h...height
V=1/3 × B × h
V=1/3 ×r^2×pi × h
V=1/3 ×12^2×pi × 8
V= 1/3 ×144×pi ×8
V=1/3 × 1152pi
V=384pi cm^3
formula: multiply the value in kilometers by the conversion '3280. 839895
Step-by-step explanation:
so, 3.76 kilometers =3.6× 3280. 839895 =12335.96 feets
First, keep in mind that two negatives make a positive:
-13w^2 + 13 + 2w^2
-11w^2 + 13
