Y=12+2x
y represents the number of pieces she now knows, x represents the number of weeks she has taken lessons, 2 is the slope (the number of pieces she'll learn each week), and 12 is the y intercept (the number of pieces she knew before taking lessons).

To solve the equation for 11 weeks, we replace x with 11.

2×11+12= 24
y=24

If 14 people show up to a cookout and you make 21 hot dogs, how many will you need to make if 105 people up?

Oksanka [162]

Answer:

Step-by-step explanation:

let x = number of of hot dogs that 105 people will do

therefore

14 people = 21 hot dogs

105 people = x hot dogs

14 x 105 people = 21 x Xhotdogs

1470 = 21X

divide through by 21

1470/21 = 21X/21

70 = X

X = 70

therefore,

105 people will makev 70 hot dogs
