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]
5. Why is it difficult to estimate 1% as a fraction with a
denominator that is less than 25?
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.

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.

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.Determine the intercepts of the line.

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.

Your team wins 16 medals at a competition. The medals are gold, silver, and bronze in a ratio of 6 : 1 : 1. How many of each medal did your team win?
Answer: 12 gold, 2 silver and 2 bronze
Step-by-step explanation:
16 is the total number of medals and in the ration 6:1:1 there are 8. To get to 16 total medals you need to double each of them. 6x2, 1x2 and 1x2. Now you have a ratio of 8:2:2. 8+2+2=16.
The number of medals of gold, silver, and bronze will be 12, 2, and 2, respectively.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
Your group wins 16 decorations at a rivalry. The decorations are gold (G), silver (S), and bronze (B) in a proportion of 6: 1: 1.
G/6 = S/1 = B/1 = x
G = 6x
S = x
B = x
Then the equation is written as,
6x + x + x = 16
8x = 16
x = 16 / 8
x = 2
Then the number of each medal is given as,
G = 6x = 6(2) = 12
S = x = 2
B = x = 2
The number of medals of gold, silver, and bronze will be 12, 2, and 2, respectively.

Write an equation in slope intercept form that represents the graph.
to get the equation of any straight line, we simply need two points off of it, let's notice the picture above, the line passes through the origin and (8 , -5), so let's use those two points then
[tex]\stackrel{origin}{(\stackrel{x_1}{0}~,~\stackrel{y_1}{0})}\qquad (\stackrel{x_2}{8}~,~\stackrel{y_2}{-5}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-5}-\stackrel{y1}{0}}}{\underset{run} {\underset{x_2}{8}-\underset{x_1}{0}}} \implies \cfrac{ -5 }{ 8 } \implies - \cfrac{5 }{ 8 }[/tex]
[tex]\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{0}=\stackrel{m}{- \cfrac{5 }{ 8 }}(x-\stackrel{x_1}{0})\implies {\Large \begin{array}{llll} y=-\cfrac{5}{8}x \end{array}}[/tex]
Which table shows equivalent ratios?
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

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.
