In the diagram below, AB|| DEF , AE and BD intersect at C, m angle B = 43 degrees, and m angle CED equals 152 degrees. Please show work correctly !!!!!!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!!
Answer:
71
Step-by-step explanation:
Answer:
3)
Step-by-step explanation:
152 - 90 = 62
180-152 = 28 which <CED and <BAC = 28.
180-28-43 = 109
<ACD = 71 because if <ACB = 109. then think of DCB as a 180 degree. 180-109. then it is 71.

The solution to the system of equation below is (−2, −1).
2x − 3y = −1
11x − 9y = −13
When the first equation is multiplied by −3, the sum of the two equations is equivalent to 5x = −10.
Which system of equations will also have a solution of (−2, −1)?
5x = −10
11x − 9y = −13
2x + 9y = −1
11x − 9y = −13
−6x + 9y = −1
11x − 9y = −13
−6x + 3y = −1
5x = −10

Answer:
5. There were 30 students in that class.
6. Drew weighed 245 pounds at the start.
Step-by-step explanation:
5. Since 3 students are absent in which represents 10% of the classroom, multiply the number 3 by 10 to get 30 students which represents the full roster.
6. 20% of his original weight is 49, multiply that number by 5 to get the original weight which is 245 pounds.
Answer:
5. 3 / 0.1 = 30 students
6. 49 / 0.2 = 245 lbs
I NEED HELP PLZ I WILL GIVE THANKS AND BRAINLIST
Answer: Infinite solutions
Step-by-step explanation:
This is because they're the same and will have the same points till the line ends.
It's when the equations intersect at a point that they have one solution.
When the lines a parallel, they have no solutions.

A survey was conducted of 880 college students attending the same university. They were offered a list of 10 different internet service providers and were asked to select the one they prefer. Can a service provider receiving only 89 votes come out on top?
Answer: Yes
Step-by-step explanation:
From the question, we are informed that a survey was conducted of 880 college students attending the same university and that they were offered a list of 10 different internet service providers and were asked to select the one they prefer.
Basee on this information, if everyone selected equal numbers, each service provider will get (880 / 10 = 88 students). In this case, if someone has 89 votes, this means that another person will get 87 votes while the remaining 8 service providers gets 88 students each. Therefore, the device provider with 89 votes can come out on top.

Cyanobacteria, also known as blue-green algae, are a kind of bacteria found in many lakes. These organisms make their own food through photosynthesis. Small animals, including mayfly larvae, eat the cyanobacteria. Small fish, such as yellow perch, eat the mayfiy larvae. The small fish provide food for larger fish, such as walleye. Choose the level of the food pyramid that represents the energy role of cyanobacteria in the lake ecosystem.

Can someone substitute this? Please and thank you
Step-by-step explanation:
soln
given
y=2x+3 -----(i)
y=-x-9 ------(ii)
now, putting value of equation (i) in (ii)
y= -x-9
or, 2x+3 = -x-9
or, 2x+x = 9-3
or, 3x = 6
or, x = 6/3
or, x = 2
again,
y = 2x+3
or, y = 2×2+3
or, y = 7
therefore, value of X and Y are 2 and 7 respectively.
write as single power of 7?
(7^2)^-2
Answer:
[tex]7^{-4}[/tex]
Step-by-step explanation:
Using the rule of exponents
[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex] , then
[tex](7^2)^{-2}[/tex]
= [tex]7^{2(-2))}[/tex]
= [tex]7^{-4}[/tex]
The sum of three consecutive odd integers is 765. What are the three
integers?
Answer: 254, 255, 256
Step-by-step explanation:
Divide the total by 3 to get the integer in the middle. 255.
Subtract 1 to get the first integer, 254.
Add 255 + 1 to get the third integer, 256.

Dylan's mother gets a restaurant bill for $25. She has a coupon for 15% off. After the discount is applied, she adds 20% tip for the server. What is the total that Dylan's mom will pay at the restaurant?
Given:
Amount of bill = $25
Coupon = 15% off
Tip = 20% after discount is applied.
To find:
The total that Dylan's mom will pay at the restaurant.
Solution:
We have,
Amount of bill = $25
Discount = 15%
Amount after discount = 25 - 15% of 25
[tex]=25-\dfrac{15}{100}\times 25[/tex]
[tex]=25-3.75[/tex]
[tex]=21.25[/tex]
So, amount after discount is $21.25.
Tip = 20%
Total Amount = Amount after discount + Tip
[tex]\text{Total Amount}=21.25+\dfrac{20}{100}\times 21.25[/tex]
[tex]\text{Total Amount}=21.25+4.25[/tex]
[tex]\text{Total Amount}=25.5[/tex]
Therefore, Dylan's mom will pay total $25.5 at the restaurant.

7. Alex makes $30,000 a year at his job
and gets $2,500 a year raise every year.
Sydney makes $40,000 a year and gets a
$2,000 raise every year. How many years
will it take for them to make the same
salary?
Answer:
It will take them 20 years to make the same salary
Step-by-step explanation:
Let us solve the question
Assume that they will have the same salary after x years
∵ Alex makes $30,000 a year at his job
∵ He gets a $2,500 a year raise every year
∵ He will work x years
→ That means his salary is the sum of a fixed amount and the raise times x
∴ His salary = 30000 + 2500(x) ⇒ (1)
∵ Sydney makes $40,000 a year
∵ He gets a $2,000 raise every year
∵ He will work x years
→ That means his salary is the sum of a fixed amount and the raise times x
∴ His salary = 40000 + 2000(x) ⇒ (2)
∵ They will make the same salary after x years
→ Equate (1) and (2)
∴ 30000 + 2500x = 40000 + 2000 x
→ Subtract 30000 from both sides
∴ 2500x = 2000x + 10000
→ Subtract 2000x from both sides
∴ 500x = 10000
→ Divide both sides by 500
∴ x = 20
∴ It will take them 20 years to make the same salary
The table shows the amount of money Tyler earns for mowing lawns. Is the
relationship a proportional relationship? Complete the explanation.
Answer:
The constant of variation 'k' is NOT constant.
Therefore, we conclude that Taylor did not charge a constant rate. The rates are not equal because his rate changed.
Step-by-step explanation:
Given the table
Number of Lawns 1 2 3 4
Amount Earned ($) 16 32 54 72
We know that when y varies directly with x, we get the equation
y ∝ x
y = kx
k = y/x
where 'k' is called the constant of proportionality.
In our case, the 'Amount earned ($) ' is represented by 'y', and the 'Number of Lawns' is represented by 'x'.
Let us check the constant of proportionality using the equation
k = y/x
k = 16/1 = 16
k = 32/2 = 16
k = 54/3 = 18
k = 72/4 = 18
It is clear that that the constant of variation 'k' is NOT constant.
Therefore, we conclude that Taylor did not charge a constant rate. The rates are not equal because his rate changed.

Answer:
The greatest common factor in that expression is 3x², giving you the expression:
3x²(-x² + 4x -7)
Step-by-step explanation:
All three terms are divisible by three:
3(-x⁴ + 4x³ - 7x²)
Each term is also divisible by x²:
3x²(-x² + 4x -7)
So the greatest common factor is 3x²
