The following items are in the shape of a square. how many squares are
in each row?
a. a waffle has 16 squares.
b. a magic square has 49 squares.
c. a tile game has 100 squares.

a. A waffle has 16 squares.

In squares there are same number of tiles in rows and columns.

When there are 16 squares that means same number of squares are in rows as well as in columns.

We can write like 4 x 4.

So, a waffle has 4 squares in each row.

b. A magic square has 49 squares.

It is 7 x 7 , so there are 7 tiles in a row.

c. A tile game has 100 squares.

Its is 10 x 10, so there are 10 square in a row.

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
