b) Xc O x/(y – z) + (a - b)
c) Xc O x/y - 2 + a - b c O
d) x/(y – z) + a – b xc

Question:

Select expression that is mathematically equivalent to

a)

b)

c)

d)

Step-by-step explanation:

Given

Required

Determine its equivalent

Start by writing y - z in bracket;

becomes

When - is used as divide, it is equivalent to /

The given expression can then be rewritten as

Hence;

is equivalent to

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
