Iwould enjoy a brief explanation for each one you! ☺️

Step-by-step explanation:

1. 4 3/4=19/4

53/2=13/2

the total change of square will be. 19/4 + 13/2= 19+26/4=45/4

2. total change is 0.7+0.4=1.1

3.-7 1/6= -43/6

3 5/6= 23/6

-43/6 + 23/6 =-20/6 = -10/3

4. metals=2.625(m)

paper=5.58(p)

glass= x

total = 9.5(t)

m + p + x = t

2.625 + 5.58 + x =9.5

8.205 + x = 9.5

x = 9.5 - 8.205

x = 1.295

Hope That Helped

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
