The multiplication property of equality could be used to solve which of the following equations?
a. (x+2)(x-3)=0
b. m +7 = -12
c. b ÷ (-2) = 18
d. -3 + y = 7

Step-by-step explanation:

C.

The multiplicative property states that by multiplying both sides of an equation gives you the same sum on both sides. By multiplying both sides by -2, the equations are the same by the property.

option C

Step-by-step explanation:

The multiplication property of equality states that same number is multiplied on both sides of the equation

A. (x+2)(x-3)=0

To solve for x we set each factor =0

B. m +7 = -12

To solve for m we subtract 7 from both sides, Its subtraction property

C. b ÷ (-2) = 18

To remove -2 we multiply both sides by -2 because -2 is in the denominator. we use multiplication property of equality

D. -3 + y = 7

To solve for y we add 3 on both sides, its addition property

10

step-by-step explanation:

7+3=10

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
