Answer:
the answer is 1/2
Step-by-step explanation:
-(-D) = -(-1/2)
2 negatives make a positive so it would be 1/2 or in other cases, 0.5
D= -1/2
So -(D)= 1/2
Then -(1/2)= -1/2

STEPS FOR SOLVING LINEAR EQUATION\(20-2(x=5)=24\)
Use the distributive property to multiply −2 by x−5.
\(20-2x+10=24\)
Add 20 and 10 to get 30.
\(30-2x=24\)
Subtract 30 from both sides.
\(-2x=24-30\)
Subtract 30 from 24 to get −6.
\(-2x=-6\)
Divide both sides by −2.
\(x=\frac{-6}{-2}\)
Divide −6 by −2 to get 3.

Margo is wrapping a box that is 7 inches long, 10 inches wide, and 4 inches high. How much wrapping paper will she need to cover the entire box?
Answers
She will need to cover six sides of the box. To calculate the surface area of the box, you'll need to add the area of each side. The formula for surface area is: 2lw + 2lh + 2wh. Plugging in the dimensions of the box, we get:
2(7 x 10) + 2(7 x 4) + 2(10 x 4) = 140 + 56 + 80 = 276
So, she will need 276 square inches of wrapping paper. But since she doesn't need to wrap the bottom of the box, we subtract one of the sides, which gives us a total of 268 square inches of wrapping paper.
To calculate the surface area of the box, you need to add the area of all six sides. The area of each side can be found by multiplying the length by the width.
- The area of the front and back sides is 7 x 4 = 28 square inches each.
- The area of the top and bottom sides is 10 x 4 = 40 square inches each.
- The area of the two side sides is 7 x 10 = 70 square inches each.
So, the total surface area of the box is 2(28) + 2(40) + 2(70) = 56 + 80 + 140 = 276 square inches.
Therefore, Margo will need at least 276 square inches of wrapping paper to cover the entire box.
Answer:280 in
Step-by-step explanation: First we multiply the length by the width and that would be 7 by 10 and we would get 70. Next we multiply the height by the total of (l x w), so 4 x 70 would be 280. Margo needs a total of 280 inches of wrapping paper to cover the entire box. Hope this helps! :)

Answers
Answer:
1. d = -6 2. n = -80
Step-by-step explanation:
If you divide 42 by -252 you get -6. And if you use your mental math you see that two negatives make a positive then you see it has to be negative and 80/4= 20 than -80/-4 = 20. Hope this helps, let me know if correct, and have a great day!!
Answer:
42d = -252 (since 42 is multiplied by d, you have to divide by 42 on both sides to get what d is)
d= -6
20 = n / (-4) (since n is being divided by -4, you have to multiply by -4 on both sides to get what n is)
n= -80
Step-by-step explanation:
to get what the variable is, you have to "undo" the operation that is being done.

Subtract 6 from both sides:
\(\dfrac{1}{2} z+6-6=-7-6\)
\(\dfrac{1}{2} z=-13\)
Multiply both sides by 2:

z = -26

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

Polygon JKLM is drawn with vertices J(−4, −3), K(−4, −6), L(−1, −6), M(−1, −3). Determine the image coordinates of L′ if the pre-image is reflected across y = −3.
L′(−3, 6)
L′(−1, 6)
L′(−1, 0)
L′(1, 0)
Answers
To reflect the pre-image across y = -3, we need to flip the entire polygon over the line y = -3. This means that the x-coordinates of each point will remain the same, but the y-coordinates will be reflected across the line.The y-coordinate of point L is -6, which is 3 units below the line y = -3. When reflected, this point will be 3 units above the line y = -3. Therefore, the image coordinates of L' will be (−1, 0), since the x-coordinate of L is -1 and the y-coordinate of L' is 3 units above y = -3, which is 0.So, the image coordinates of L' are (−1, 0).

Answer: 76m
Step-by-step explanation:
First, start by splitting the figure into 2 smaller rectangular prisms; this can be done vertically or horizontally. I'll solve both ways so you can understand better.
Method 1: Splitting the figure into 2 rectangles vertically
The formula for volume or a rectangular prism is V = Bh. So, you start by finding the base of rectangular prism 1, which you can solve by multiplying the width (2m) by the length (4m) which is given in the figure. This gives you 8m which is the base. Now, if you look at the figure you can see that the height is 5m, so to find the volume of rectangular prism 1, you would multiply 8m (the base) by 5m (the height), and the answer is 40m.
Next, you would solve the same way to find the volume of rectangular prism 2. The given length is 4m and you can figure out the width by subtracting 5m - 2m which gives you 3m. Now you know your base which is 4m. To solve for the height you must again subtract 5m - 2m to get 3m. To find the volume, plug the values into the formula and multiply 4 X 3 X 3. The volume of rectangular prism 2 should come out to be 36m.
The last step is to add both of these volumes together. The volume of rectangular prism 1 + volume of rectangular prism 2 = Volume of the entire figure. The final volume is 40m + 36m = 76m.
Method 2: Splitting the figure into 2 rectangles horizontally
The formula for volume or a rectangular prism is V = Bh. So, you start by finding the base of rectangular prism 1, which you can solve by multiplying the length (2m) by the width (4m) which is given in the figure. This gives you 8m which is the base. Now, if you look at the figure you can see that the height is 2m, so to find the volume of rectangular prism 1, you would multiply 8m (the base) by 2m (the height), and the answer is 16m.
Next, you would solve the same way to find the volume of rectangular prism 2. The given length is 5m and the given width is 4m. Now you know your base which is 4m. To solve for the height you must subtract 5m - 2m to get 3m. To find the volume, plug the values into the formula and multiply 5 X 4 X 3. The volume of rectangular prism 2 should come out to be 60m.
The last step is to add both of these volumes together. The volume of rectangular prism 1 + volume of rectangular prism 2 = Volume of the entire figure. The final volume is 16m + 60m = 76m.
Hope this helps!

Given the equation y = -x - 1, we see that the slope (the coefficient of the x term) is -1. A line perpendicular to this one has a slope which is the negative reciprocal of the given equation: +1.
Using the point-slope formula for the equation of a straight line, we get:
