consider the sequence of steps to solve the equation:
5(x - 3) =
7x
2

step 1 ⇒ 10(x - 3) = 7x
step 2 ⇒ 10x - 30 = 7x
step 3 ⇒ 3x - 30 = 0
step 4 ⇒ 3x = 30
step 5 ⇒ x = 10

identify the property of equality which gets us from step 3 to step 4.
a) division property
b) addition property
c) subtraction property
d) multiplication property

Addition property.

Step-by-step explanation:

From step 3 to step 4, you are adding 30 to both sides of the equation. This makes the property addition.

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
