Answer: Lucy ate more pizzas because he ate more inches of pizza than Anthony.

Step-by-step explanation:

Anthony eats 2 slices of a large 18 inch pizza. Total number of slice in the 18 inch pizza is 8

The size of one slice in inches would be total length of pizza / number of slices. It becomes

18 / 8 = 2.25 inches

Anthony ate 2 ×2.25 = 4.5 inches of pizza.

Lucy eats 4 slices of a 12 inch pizza.

Total number of slice in the 12inch pizza is 8

The size of one slice in inches would be total length of pizza / number of slices. It becomes

12 / 8 = 1.5 inches

Lucy ate 4 × 1.5 = 6 inches of pizza.

Lucy ate more pizzas because he ate more inches of pizza than Anthony.

Help? Please? This is algebra math

Over [174]

Answer:

You count the blocks and then put the amount of blocks before:)

(That sounds confusing but it sounds harder than it is)

The answer would be 3xy + 4x

Step-by-step explanation:

How many xy blocks are there? yea there's 3 so you do 3xy

you can't add xy and x blocks together because xy is a different unit than x (xy is x times y) so then you'd count the other x blocks seperately

(I'm sorry if I'm wrong on this lol)
