Ben is 3 years older than Evan. The sum of their ages is 41. How old is Evan? I’ve been stuck on this for a long time so please someone help solve this. Thanks!
Answer:
Evan is 19 years old
Step-by-step explanation:
let 'e' = Evan's age
let 'e+3' = Ben's age
e + e + 3 = 41
2e + 3 = 41
2e = 38
e = 19

There are 18 people waiting for the train. Eight-ninths of them have an umbrella. How many people waiting for the train have an umbrella?
Answer:
Step-by-step explanation:
Ok, so there are 18 people. If 8/9 have umbrellas, how many have umbrellas?
There is a simple solution to this.
First, lets find out how much people is 1/9
We can do this by dividing 18 by 9 to get 2
So 1/9 of the group is 2 people.
Now you can use this to find 8/9 by multiplying 2 by 8
This gives you the total of 16
Another way you could do this was take the answer from the first step and subtract that from the 18
9/9 - 1/9 = 8/9 => 18 - 2 = 16
Hope this helps! =)

Reflect triangle A in the line y= 1 . PLEASE I GIVE S LOT OF POINTS !!!!
Can somebody solve this please?
=========================================================
Explanation:
The angle x is a base angle of the isosceles triangle. The unmarked angle is also x, since the base angles of isosceles triangles are congruent.
For any triangle, the three angles always add to 180
x+x+36 = 180
2x+36 = 180
2x = 180-36
2x = 144
x = 144/2
x = 72

In Mrs. Smith's class, only 50% of the students brought a pencil, while 1 only had a pen, and the rest didn't bring anything to write with at all. If there are 32 students in the class, how many students didn't bring a pencil to write with?
Quick Answer:
15 students did not bring a pencil to write with
Answer:
15 students
Step-by-step explanation:
Because you need to find out how many students didn't bring something to write with, you need to subtract the amount of students in the class by the number of students who did bring something to write with. So, 32÷2=16, and 16+1 is 17. So, 32-17=15. Therefore, the answer would be 15 students didn't bring something to write with.

can someone answer this for me im really bad at math 6x+17
Answer:
It cannot be answered if we don't figure out what x means. IF we knew what X is we can multiply 6 by x and then add 7.
an example would be if x was 3. we could figure out the answer by just doing (6*3)+7=25
Twelve students have an equally likely chance of being selected in a drawing at school. Eight are 7th graders and four are 8th graders. What is the probability that an 8th grader will be selected?
The probability that an 8th grader will be selected from selection of a student for the considered case is 1/3
How to calculate the probability of an event?Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.
Then, suppose we want to find the probability of an event E.
Then, its probability is given as
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]
where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.
For this case, it is given that:
Twelve students have an equally likely chance of being selected in a drawing at school.Out of those 12, number of 7th grader = 8Out of those 12, number of 8th grader = 4To find: Probability that an 8th grader will be selected
Take an event E as:
E = event of selecting an 8th grader.
Then, as there are 4 such students, so event E can be done in 4 ways.
Total students are 12, so selecting a student (whether E occurs or not) is do-able in 12 ways.
As all the students are equally likely, we can use the above definition of probability of an event E, and therefore, we get:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{4}{12} = \dfrac{1}{3}[/tex]
Thus, the probability that an 8th grader will be selected from selection of a student for the considered case is 1/3

Answer:
29.4
Step-by-step explanation:
The meal costs $30
Minus discount (10%) costs $27
Then she pays the bill (8%) which equals 2.4
So the answer is 27 + 2.4 = 29.4

Which function is equivalent to f(x)=4x2−12x+9?
Question 6 options:
(4x−3)(x−3)
(4x+3)(x+3)
(2x+3)2
(2x−3)2
Answer:
D. f(x) = (2x - 3)²Step-by-step explanation:
Given function:
f(x) = 4x² - 12x + 9Use identity:
(a ± b)² = a² ± 2ab + b²We can see:
a = 2x and b = 3Apply:
f(x) = (2x - 3)²Correct choice is D
[tex]\\ \tt\hookrightarrow f(x)=4x^2-12x+9[/tex]
Factorise[tex]\\ \tt\hookrightarrow f(x)=2x^2-2(2x)(3)+3^2[/tex]

Divide: (x²-11x+30 ) by (x-5)
Answer:
(x + 5)(x - 6)
First, start with the distributive property
=(x)(x) + (x)(-6) + (5)(x) + (5)(-6)
= x² - 6x + 5x - 30
= x² - x - 30
Thus,
The correct answer is option A

Describe the relationship between BOC and COD what is the sum of their angle measures
Answer: <BOC and <COD are supplementary. The sum of their angle measures is 180 degrees.
Step-by-step explanation:
Since angles BOC and COD both form a horizontal line (line BOD) when added together, the two angles are supplementary. Supplementary angles always equal 180 degrees when added together because they form a straight line, or half of a circle.
Therefore, <BOC and <COD are supplementary, and the sum of their angle measures is 180 degrees.
