Answer:

Step-by-step explanation:

Adam plans to choose a video game from a section of the store where everything is 75% off.

The expression written by him for this situation is d - 0.75d.

Here, the part d represents the sale price before discount and the part 0.75d is the discount amount.

The expression written by Rena is 0.25d.

Here, the part 0.25d is the price after discount. Since 75% is the discount, the rate after disount is 25% and 25% of d is 0.25d.

24 = -6 (m+1) + 18 <br> What is the answer?

kirill115 [55]

Answer:

m = -2

Step-by-step explanation:

24 = -6(m + 1) + 18 (Given)

24 = -6(m) + -6(1) + 18 (Distributive Property of Equality)

24 = -6m - 6 + 18 (Simplify)

24 = -6m + 12 (Simplify)

24 - 12 = -6m + 12 - 12 (Subtraction Property of Equality)

12 = -6m (Simplify)

$\frac{12}{-6} = \frac{-6m}{-6}$ (Division Property of Equality)

-2 = m (Simplify)

m = -2 (Distributive Property of Equality)

How many solutions does the equation 3x + 6 = −1 − 3 + 4x have? (5 points)

lianna [129]

Answer:

The equation has only one solution which is:

$x = 10$

Step-by-step explanation:

Given the equation

$3x\:+\:6\:=\:-1\:-\:3\:+\:4x$

Let us solve the equation to determine the type of the equation

$3x\:+\:6\:=\:-1\:-\:3\:+\:4x$

subtract the number: -1 - 3 = -4

$3x+6=4x-4$

subtract 6 from both sides

$3x+6-6=4x-4-6$

$3x=4x-10$

subtract 4x from both sides

$3x-4x=4x-10-4x$

$-x=-10$

Divide both sides y -1

$\frac{-x}{-1}=\frac{-10}{-1}$

$x=10$

Therefore, the equation has only one solution which is:

$x = 10$
