Graph the linear equation 5x + 2y = 4
Answer:
x | y
0 | 2
2 | -3
Step-by-step explanation:
This assignment is due soon! If someone can help it would be great. It is about triangle angle sun theorem.
Ok so basically we know that all the angles in a triangle add up to 180 degrees.
That means
(x-7) + (2x) + (x+11) = 180 because we combined all the angle measures.
To solve this equation we've got to combine like terms.
We can combine the x's together so we have 4x + (-7) + 11 =180.
Then we can combine -7 and 11 to get 4 because 11-7=4.
Now our equation is 4x+4=180.
We can subtract 4 from both sides of the equation to get 4x=176.
Then simplify this by doing 176/4=44.
That means x=44.

(I'm gonna be posting/asking a lot of questions from Alek for a bit today.
So be ready/prepared!)
Answer: 12 furniture sets
Step-by-step explanation: This question is like # of different ways to choose the furniture set.
3 beds x 2 desks x 2 dressers = 3 x 2 x 2 = 12 furniture sets.
20-2(x-5)=24
find the value of x
Answer: [tex]x=3[/tex]
Step-by-step explanation:
STEPS FOR SOLVING LINEAR EQUATION[tex]20-2(x=5)=24[/tex]
Use the distributive property to multiply −2 by x−5.
[tex]20-2x+10=24[/tex]
Add 20 and 10 to get 30.
[tex]30-2x=24[/tex]
Subtract 30 from both sides.
[tex]-2x=24-30[/tex]
Subtract 30 from 24 to get −6.
[tex]-2x=-6[/tex]
Divide both sides by −2.
[tex]x=\frac{-6}{-2}[/tex]
Divide −6 by −2 to get 3.
[tex]x=3[/tex]

Which product is negative?
Answer: The Answer to your question would be D-Number 4
Step-by-step explanation: A Negative Number Multiplied by a Negative number is Positive. Each negative number cancels out the other. In A., there are 2 negatives, and 2 positives, so it would be a Positive. In B., There are 3 negatives, but there is a 0, and anything times 0 is 0, And 0 is neither negative nor positive. In C., All of the numbers are negative, so they cancel each other out, and make a positive. Lastly, In D., there is one positive, and three negatives. 2 Negatives cancel eachother out, and there is one negative and one positive remaining. A positive multiplied by a negative is also negative. So then the negative multiplied by the positive is negative.
Hope this Helps!

How many sides do 4 nonagons and 4 triangles have in all?
Answer: Regular nonagon has 9 sides. 9×9×9×9 is 6,561 which is the total of 4 nonagons. A regular triangle has 3 sides. 3×3×3×3 is 81 which is the total of 4 triangles. When you add 6,561 and 81 together, it's 6,642. Therefore, 6,642 is the 4 nonagons and 4 triangles in total.
Which number line represents 5/4?
Answer:
D.
Step-by-step explanation:
Determine 5/4 as a mixed number. 5/4 as a mixed number is 1 1/4.Eliminate the answer choices that are less than 1 or greater than 2 because 1 1/4 is between 1 and 2. In this case, you can now eliminate C.Eliminate the answer choices that are greater than 1 1/2 because 1 1/4 is between 1 and 1 1/2. In this case, you can now eliminate A.With your remaining answer choices, determine the number that each number line represents. You can see that B is split into sixths and five spaces are shaded, making it 6/5. On the other hand, D is split in fourths and 5 spaces are shaded, making it 5/4.With this information, you now know that D represents 5/4 or 1 1/4 and is your answer.I hope this helped. Comment if you have additional questions.
This assignment is due soon! If anyone can help me with this problem it would be great!
Answer:
z=32
Step-by-step explanation:
sum of these angles is equal to 180 so we add all of these angles and set it equal to 180
Z+12+2z+z+40=180
4z+52=180
-52. -52
4z=128
/4. /4
z=32
Hopes this helps
Answer:
z = 32° (degrees)
Step-by-step explanation:
Angles in triangle = 180° (degrees)
z + 12 + z + 40 + 2z = 180
2z + 2z + 12 + 40 = 180
4z + 52 = 180
4z = 180 - 52
4z = 128
z = 128/4 → 32

Answer: look up slope intercept calculator
Step-by-step explanation:
Two angles of a triangle measure 27 and 17. What is the measure of the third angle?
Answer:
136⁰
Step-by-step explanation:
Three angles of a Triangle always addvup to 180⁰
27⁰ + 17⁰ + ×⁰= 180⁰
44⁰ + x⁰ = 180⁰
× = 180 - 44
= 136⁰
Therefore Angle 3 = 136⁰
Answer:
The third angle is 136
Step-by-step explanation:
The three angles of a triangle add to 180
27+17+x = 170
Combine like terms
44+x = 180
Subtract 44 from each side
44+x-44 =180-44
x =136
Is there any advantage to describing the links using a decimal such as 1.82 m instead of using a fraction such as one and 82/100 or one and 42/50 of a meter
Answer: Not really
Step-by-step explanation:
Decimals just look better than fractions. People don't normally say, "I have two and 4/25 dollars!" They just don't want to have to work in order to determine how much something costs or how far someone walked. If the question states clearly to write it as a fraction then do so, but otherwise, do it however you want to.
Josh needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 4.25 hours and charged him $167 for parts. The total was $655.75. Write and solve an equation which can be used to determine

Choose the description that matches the graph.
A) The graph increases linearly, then decreases linearly, then increases both linearly and nonlinearly.
B) The graph decreases linearly and then increases.
C) The graph starts at a constant rate, then decreases linearly, then increases linearly, and then increases linearly.
D. The graph starts at a constant rate, then decreases, and then increases nonlinearly.
Answer: C
Step-by-step explanation:
Jessica takes a road trip.
She begins by driving slowly at a constant speed for a short distance and then stopping at a stop sign.
After the short stop she drives again at a faster constant speed than before, and then she enters the highway after a short distance.
Once on the highway, she drives at an even faster constant speed.
Which of the following graphs best illustrates the part of Jessica’s road trip described?
Answer:
a or b
Step-by-step explanation:
im not entirely sure try to think it out!
Answer:
It is: A
Step-by-step explanation:
You can see that she is driving at the slowest speed at the start. She hits the stop sign and slows down. Drives faster but not the fastest. Hops on the highway and that, right there is when she will drive the fastest.
Graph the inequality:
Elaina guessed on a maximum of 3 questions, q, on the science test. (That is a Q)
Answer: Q≤3
Step-by-step explanation:
Elaina guessed on a max of 3 questions. So he/she could have guessed on 3 or less (3 included.) Since 3 is included the dot at 3 would be filled in (aka closed circle.) And the inequality would be pointing left.
Answer:
The answer is the image.
Step-by-step explanation:
Determine the equation represented by the word problem, which is [tex]q\leq 3[/tex].Graph the equation accordingly. Because the range includes 3, you put a closed circle on 3. And since it also includes anything less than 3, you arrow should go from right to left.
