Two intersection lines. Angle formed at the top is labeled 3 x plus 50 degrees. Angle formed at the bottom is labeled 6 x minus 10 degrees.
Answers
Answer:
20
Step-by-step explanation:
So, both of those angles are equal to each other because they are congruent. So, we can set their equations equal to each other to find x.
Solve it like this:
3x + 50 = 6x - 10
-3x -3x (always subtracts the variables first (x), then the other numbers)
50 = 3x -10
+10 +10
60 = 3x
Then, divide both sides by the number next to the variable (3)
60/3 = 20, 3x/3 = x
So, you get:
20 = x

Step-by-step explanation:
[tex]12 - 2(3h) = - 18 \\ 12 - 6h = - 18 \\ - 6h = - 18 - 12 \\ - 6h = - 30 \\ h = \frac{ - 30}{ - 6} \\ h = 5[/tex]
hope it helps you<3Answer:
H=5
Step-by-step explanation:
Simplifying the equation
We multiply 2(3H) =6H, so the equation is now 12-6H=-18
Isolating the Variables
Then, we subtract 12 from both sides, giving us -6H = -30
Finding H
Finally, we divide both sides by -6, so H= 5

Answers
Answer:
Perimeter = 12
Area = 8
Step-by-step explanation: For the perimeter add all the sides so the top and bottom is both 2 so 2+2 = 4.
For the sides its both 4 so 4 + 4 = 8.
8 + 4 = 12
So the perimeter is 12.
For area just count all the blue squares and there is 8 squares.
So the area is 8.

What type of transformation happened from (x,y) --> (-x,y)?
-----
A.Rotation 90*
B.Reflection over the y-axis
C.Translation left 1
D.Reflection over the x-axis
Answers
Answer:
B
Step-by-step explanation:
This is a reflection over the y-axis. The x value is changing sign while the y value is staying the same. The general rule for a reflection over the y axis is (x,y) --> (-x,y), and similarly for a reflection over the x axis is (x,y) --> (x,-y). When you reflect a point over an axis, you flip the sign of the opposite value.
Molly is painting a model house and needs to know how much paint she will need. She knows the surface area of the prism is 216 square inches and the surface area of the pyramid is 84 square inches.
1. Which surface is shared by the two solids? What are the dimensions of this surface?
2. There is another surface that Molly does not need to paint, because it won’t show when she displays the model house. Describe that surface, and explain why it doesn't need to be painted.
3. To find the area Molly needs to paint, she should add the surface areas of both solids and subtract:
twice the area of the triangle
twice the area of the square
three times the area of the square
the area of the square
4. Find the area Molly needs to paint. Show your work, and be sure to include units with your answer.
Oh and here's an image to help you out
Answers
Answer:
1. Base of pyramid; 6 in by 6 in
2. Base of prism; Its dimensions are also 6 in by 6 in, located at the bottom of the house and will not be seen, so it does not require painting.
3. twice the area of the square
4. Area = 228 inches squared
Step-by-step explanation:
For question 4, the area Molly needs to paint is found by adding all the surface areas and subtracting the 2 surfaces that will not be painted: base of pyramid and base of prism (outlined in red). According to the picture, these are both squares with 6 by 6 dimensions.
Step 1. Add all surface areas togetherPrism: 6 surfaces
Surface area = 216 inches sq
Front = 6 x 6 = 36 Back = 6 x 6 = 36Top = 6 x 6 = 36Bottom (base) = 6 x 6 = 36Side = 6 x 6 = 36Other side = 6 x 6 = 36Pyramid: 5 surfaces
Surface area = 84 inches sq
Bottom (base) = 6 x 6 = 36Front triangle = (6 x 4)/2 = 12Back = (6 x 4)/2 = 12Side = (6 x 4)/2 = 12 Other side = (6 x 4)/2 = 12TOTAL surface area: 216 inches + 84 inches = 300 inches sq
Step 2. Subtract surfaces that are NOT being painted300 - base of pyramid - base of prism
300 - 2(36)
300 - 72
228 inches sq

QUICK I NEED AN ANSWER ASAP
Answers
Lucie must buy 5 more than half of Suzie's purchase to have 10 more cards than two thirds of the girls’ total
How to determine the number of cards?Represent Lucie's card with L and Suzie's card with S.
So, the total number of cards is:
Total = L + S
Lucie's number of cards can be represented as:
L = 10 + 1/3(L + S)
Multiply through by 3
3L = 30 + L + S
Subtract L from both sides
2L = 30 + S
Divide by 2
L = 15 + 0.5S
Let x represents the additional number of cards.
So, we have:
x + L = 10 + 2/3(L +S)
Substitute L = 15 + 0.5S
x + 15 + 0.5S = 10 + 2/3(15 + 0.5S + S)
Evaluate the sum
x + 15 + 0.5S = 10 + 2/3(15 + 1.5S)
Expand
x + 15 + 0.5S = 10 + 10 + S
Evaluate the sum
x + 15 + 0.5S = 20 + S
Subtract 0.5S from both sides
x + 15 = 20 + 0.5S
Subtract 15 from both sides
x = 5 + 0.5S
The above means that Lucie must buy 5 more than half of Suzie's purchase to have 10 more cards than two thirds of the girls’ total
