To solve the equation −3x+4=−8, we need to isolate the variable x.

First, subtract 4 from both sides to get rid of the constant on the left side:

−3x = −12

Next, divide both sides by -3 to solve for x:

x = (-12)/(-3) = 4/3

So the solution is x = 4/3.

To solve the equation −0.1w+23.2=−0.8, we need to isolate the variable w.

First, subtract 23.2 from both sides to get rid of the constant on the right side:

−0.1w = −0.8 - 23.2
−0.1w = −24

Next, divide both sides by -0.1 to solve for w:

w = (-24)/(-0.1) = 240

So the solution is w = 240.

To solve the equation 4−2x=10, we need to isolate the variable x.

First, subtract 4 from both sides of the equation to get rid of the constant on the left side:
4 - 2x - 4 = 10 - 4
-2x = 6

Next, divide both sides of the equation by -2 to solve for x:
(-2x) / -2 = 6 / -2
x = -3

So the solution is x = -3.

The correct equation that represents this situation is:

4.5d = 75

This equation states that the cost of each doll, $4.50, multiplied by the number of dolls, d, equals the total amount Mariah has to spend, $75.00.

To solve the equation −15y+3=−7, we need to isolate the variable y.

First, subtract 3 from both sides of the equation to get rid of the constant on the right side:
−15y + 3 - 3 = −7 - 3
−15y = -10

Next, divide both sides of the equation by -15 to solve for y:
(-15y) / -15 = -10 / -15
y = 2/3

So the solution is y = 2/3.

To solve the equation −1/5y + 3 = −7, we need to isolate the variable y.

First, subtract 3 from both sides of the equation to get rid of the constant on the right side:
−1/5y + 3 - 3 = −7 - 3
−1/5y = -10

Next, multiply both sides of the equation by -5 to solve for y:
(-1/5y) * -5 = -10 * -5
y = 50

So the solution is y = 50.

Let's represent the number of cupcakes that JoJo decorates as J.

According to the problem, Darcy decorates 8 cupcakes, which is 2 more than 1/3 of the number of cupcakes that JoJo decorates.

We can set up the equation as follows:
8 = (1/3)J + 2

Now, let's solve for J (the number of cupcakes JoJo decorates).

First, subtract 2 from both sides of the equation:
8 - 2 = (1/3)J + 2 - 2
6 = (1/3)J

To eliminate the fraction, multiply both sides of the equation by 3:
3 * 6 = 3 * (1/3)J
18 = J

Therefore, JoJo decorates 18 cupcakes.

The correct answer is:

The product is positive if the signs of the factors are the same.

When multiplying two rational numbers, if both factors have the same sign (either positive or negative), the product will be positive.

To return to the initial temperature of 81°F, we need to find the difference between the final temperature and the initial temperature.

The temperature initially was 81°F. Then it dropped 9°F and rose 5°F.

To find how much the temperature needs to rise or fall to return to 81°F, we need to calculate the difference between the final temperature and 81°F.

Final temperature = 81°F - 9°F + 5°F = 77°F

The temperature needs to rise 4°F to return to the initial temperature of 81°F.

To find the distance from the basement floor to the roof, we need to calculate the difference between the elevations of the two.

The elevation of the basement floor is -15 ft and the elevation of the roof is 37 ft.

To find the distance, we need to subtract the elevation of the basement floor from the elevation of the roof.

Distance = 37 ft - (-15 ft) = 37 ft + 15 ft = 52 ft

So, the distance from the basement floor to the roof is 52 feet.
