Which number line represents 5/4?

Answers

D because 5/4 is equal to 1 and 1/4. Since d has a number line split into fours then that is the answer. Hope this helps.

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.

y=5x+15

To make an equation for this line, you need to figure out the values for the slope and the y-intercept and plug them into the formula y=mx+b

The line is going up 5 over 1 which means the slope(m) is 5

The line passes through the y intercept at 15 which means that the y-intercept(b) is 15
Correct answer y=5x+15

\Big))right parenthesis

Answers

Answer:

x-intercept is -14/9 and y-intercept is -14

Step-by-step explanation:

Given equation is:


Determine the intercepts of the line is
y = (10/33)x

Solving step :

1. Find the y-intercept/zero

• Substitute y = 0
To find the y-intercept/zero, substitute y = 0.
y = 10x – 32y
0 = 10x- 32*0

• Calculate the product.
Any expression multiplied by 0 equals 0.
0 = 10x- 32*0
0 = 10x – 0

• Remove 0.
Removing 0 doesn't change the value, so remove it from the expression.
0 = 10x – 0
0 = 10x

• Swap the sides.
Swap the sides of the equation.
0 = 10x
10x = 0

• Divide both sides.
Divide both sides of the equation by 10.
10x = 0
10x ÷ 10 = 0 ÷ 10
Any expression divided by itself equals 1.
X = 0 ÷ 10
0 divided by any nonzero expression equals 0.
X = 0

2. Find the y-intercept.

• Substitute x = 0
To find the y-intercept, substitute x = 0.
y = 10x – 32y
y = 10*0 - 32y

• Solve the equation.
Solve the equation for y.
y = 10*0 – 32y
Any expression multiplied by 0 equals 0.
y = 0 – 32y
Removing 0 doesn't change the value, so remove it from the expression.
y = -32y
Move the variable to the left-hand side and change its sign.
y + 32y = 0
Collect like terms.
33y = 0
Divide both sides of the equation by 33.
y = 0

3. Find the slope-intercept form.

• Move the variable to the left.
y = 10x – 32y
Move the variable to the left-hand side by adding its opposite to both sides.
y + 32y = 10x - 32y + 32y
Since two opposites add up to 0, remove them from the expression.
y + 32y = 10x

• Collect like terms.
y + 32y = 10x
If a term doesn't have a coefficient, it is considered that the coefficient is 1.
1 y + 32 y
Collect like terms by adding their coefficients.
(1 + 32)y
Add the numbers.
33y
We did it!
y + 32y = 10x
33y = 10x

• Divide both sides.
Divide both sides of the equation by 33.
33y = 10x
33y ÷ 33 = 10x ÷ 33
Any expression divided by itself equals 1.
y = 10x ÷ 33
Write the division as a fraction.
y = (10/33)x

[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]

Step-by-step explanation:

Decimals just look better than fractions. People don't normally say, "I have two and 4/25 dollars!"

If the question states clearly to write it as a fraction then do so, but otherwise, do it however you want to.

Two angles of a triangle measure 27 and 17. What is the measure of the third angle?

Answers

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

Which product is negative?

Answers

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.

This assignment is due soon! If someone can help me answer this it would be amazing. It is about Exterior Angle Theorem.

Answers

Answer = 95


180-(u+(u-47)) = 180 - (u + 48)

180 - (u + 48) is the unknown angle in the triangle as angles on a straight line = 180


180-(u+(u-47)) is also the unknown angle in the triangle as total angles in a triangle add up to 180.

180-(u+(u-47)) = 180 - (u + 48)

180-(u+u-47) = 180 - (u + 48)

180-(2u-47)= 180 - (u + 48)

180-2u+47 = 180 - u - 48

227-2u = 132-u

227-132 = -u+2u

95 = u
