Tell whether the angles are complementary or supplementary. Then find the value of x.
the angles are complementary because they add up to 90° because of the red square. x=20
Step-by-step explanation:
4x-5+15=90
4x+10=90 subtract 10 from each side
then you get left with 4x=80
divide 4 from each side then you get left with x=20 and to check just substitute 20 where x is so 4(20)-5= 80-5=75 +15=90.

Answer:
3 /4 of 2 is the answer to the question
Attachment Below- help would be appreciated! :)
Answer:
A, B, C, E, and F
To solve this problem, you should make sure to find the equation first. Start by doing rise/run with your two given points on the graph. From the point (-1,1) you rise 4 and then run 16 over to the point (3,2). That gives us a slope of 4/16 which can then be simplified to 1/4. That means that letter F tells us the equation of the line is y= 1/4x + 5/4.
From there you want to check your points, (3,2) and (-1,1). The first number is always x and the second number is always y. So you plug the point numbers into the equation we just found to see if they work. In the photos I inserted are how to do this step.
Once you have checked your points and you know for sure they're solutions, that gave you letters A and B. Since the point (1, 3/2) is also given in one of the answers we should check that point as well. (Also done in one of the photos) Since the point came out correctly that gives us letter C and also tells us there is more than 2 solutions. This means that letter E is also correct.

To pass her test, Tori needs to answer at least 65% of the questions correct. If there were 60
questions and she got 42 correct, did she pass? All work MUST be shown to justify your
answer.
Step-by-step explanation:
To obtain score of 80% on entire exam means the student have to answer
(80/100)×80 = 64 correct answers
Student have already answered 75% of the first 60 questions correctly meaning
(75/100)×60=45 correct answers from first 60 questions
Remaining correct answers s/he have to answer
64-45=19
So from remaining 20 questions s/he have to answer 19 correct questions that is
20 × (x/100) = 19
x = 19 ×(100/20)
x = 95%

Answer: 4m²-28m+49
Step-by-step explanation:
(2m-7)² can be written as (2m-7)(2m-7).
You would have to multiply it out like this:
2m times 2m=4m² (2x2=4 and mxm=m²)
2m times -7=-14m (2x-7=-14 then put a m on it)
-7 times 2m=-14m
-7 times -7=49
The equation would then look like this:
4m²-14m-14m+49
Then you would have to collect like terms. Like terms are terms with the same variables and powers. It will then look like this:
4m²-28m+49
Hope this helps :)

City A and City B had two different temperatures on a particular day. On that day, four times the temperature of City A was 8° C more than three times the temperature of City B. The temperature of City A minus twice the temperature of City B was −3° C. The following system of equations models this scenario:
4x = 8 + 3y
x − 2y = −3
What was the temperature of City A and City B on that day?
City A was 5° C, and City B was 4° C.
City A was 3° C, and City B was −1° C.
City A was 8° C, and City B was −3° C.
City A was 5° C, and City B was −5° C.
Answer:
City A was 5 and city B was 4
Step-by-step explanation:
Use substitution. Move 2y over so you have x=-3+2y
Plug that into 4x=8+3y
4(-3+2y)=8+3y
-12+8y=8+3y
subtract 3y from both sides
add 12 to both sides
5y=20
20 divided by 5
y=4
then youd plug it into the other equation
x-2(4)=-3
x-8=-3
x=5
therefore the answer is A

A plumber has a 2-meter length of pipe. He needs to cut it into sections that are 10 centimeters long. How many sections will he be able to cut? (I will give brainliest if you answer first)
Answer:
20 - 10 cm sections can be cut from a pipe of original length 2 m
Step-by-step explanation:
Convert 2 meters to cm:
2 m 100 cm
------ * ---------------- = 200 cm
1 1 m
Next, divide this 200 cm total length by (10 cm/section) to determine the number of sections:
200 cm
--------------------- = 20 sections
10 cm/section
20 - 10 cm sections can be cut from a pipe of original length 2 m
