Answer:
6 hot dogs, 2 drinks
Step-by-step explanation:
let y = number of hot dogs
let x = number of drinks
system:
y = 3x
4.5y + 2.25x = 31.50 (standard form: y = -1/2x + 7)
if you graph the system, lines intersect at (2, 6)
Let the width be x
width = x
length = 2x - 3
Perimeter = x + 2x - 3 + x + 2x - 3 = 6x - 6
6x - 6 = 78
6x = 78 + 6
6x = 84
x = 14 cm
2x - 3 = 2(14) - 3 = 25cm
The width is 14cm and the length is 25cm
Hello from MrBillDoesMath!
Answer:
36
Discussion:
36 = 6^2 so is a power of 6
The other choices are multiples of 6 not powers of 6 (e.g. 24 = 6*4, 12 = 6*2, 18 = 6*3)
