{An angle measures 150° less than the measure of its supplementary angle. What is the measure of each angle?}
Answers
Answer:
165° & 15°
Step-by-step explanation:
Let the first angle be 'a'
second angle be (a-150°)
a+(a-150°) = 180°
2a=180°+150°
2a=330°
a=330/2
a=165°
first angle is 165°
second angle is 165-150=15°

Answer:
p < 8
Step-by-step explanation:
Let p = number of pounds of candy Lena will buy
Given:
Candy = $5 per poundLena will spend less than $40Create an inequality using the given information:
⇒ 5p < 40
Solve the inequality:
⇒ 5p < 40
Divide both sides by 5
⇒ p < 8
The inequality to solve this would be 5p < 40
In the equation you are multiplying 5 by p, so you do the opposite and divide 5 and 40 by 5
5 divided by 5 cancels out, and 40 divided by 5 = 8. Take the leftover p and the < and make an inequality with 8. p < 8

x = 5 makes 2x≤ 10 true but not 2x < 10 because "≤" means less than or equal to, which means 2x would be the same as 10, so 10 ÷ 2 = 5, x = 5.
Answer:
Step-by-step explanation:
2x ≤ 10, when x = 5
2(5) ≤ 10
10 ≤ 10 (10 is less than OR equal to 10)
2x < 10, when x = 5
2(5) < 10
10 < 10 (10 is less than 10) - that is false
x = 5 does not makes 2x < 10 true because 10 can't be less than 10.

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.

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

∠M and ∠Nare supplementary. If m∠N= 33°, what is ∠M?
Answers
Answer:
∠M will be 147°
Step-by-step explanation:
Supplementary means adding up to 180° so take your 180° to subtract 33° from it and you'll have your answer.
Answer:
147
Explanation:
Supplementary angles all equal to 180, so that means that <M and <N must be both equal to 180.
If you want to find <M, you have to do 180 - 33, which equals to 147.

this is NOT 0/0. you can't add numerator and denominator. when you have the same denominator, you can only add the numerator.
and don't forget : -×- and -/- are both + !
2B
you do not multiply anything. you ADD (but again NOT the denominators) !
and +×- or +/- = - !
overall this this adding a negative number to the same positive number. the result : always 0
2C
cannot be added like that. first you would have to bring both to a common denominator. but then you ADD !

lucie and suzie buy greeting cards. lucie buys 10 more cards than one third of the girls’ total. how many more cards should suzie buy so that she has 10 more cards than two thirds of the girls’ total? assume that lucie does not make any purchases after her initial purchase.
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

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

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.
