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

Determine the intercepts of the line.

xxx-intercept: \Big((left parenthesis
,,comma
\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

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.

Which equation applies the associative property of multiplication?

A: 4/9 x (-3/8) x 9/4 = 4/9 x 9/4 x (-3.8)

B:​ −12/5 x (7/12 x 1/9) x 8/5 = (−12/5 x 7/12) x (1/9 x 8/5)

C: ​(−4/11 − 2/3) − 3/4 = −4/11 − (2/3 − 3/4)

D:​ 1/2 x (5/8 + 3/6) = (1/2 x 5/8) + (1/2 x 3/6)

Answers

Answer: B

Explanation:

The associative property of multiplication is a rule that states the result of three numbers being multiplied is the same regardless of the order of the numbers. In choice c, -12/5, 7/12, and 1/9 are being multiplied by each other on both sides of the equation, but they are in different orders, hence Choice C applies the associative property of multiplication.

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

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.

[tex]30-2x=24[/tex]
