Which expression is equivalent to 4(−1.3s − 2.7)?

−5.2s − 2.7
−5.2s − 10.8
−2.7s − 2.7
−2.7s − 10.8

first response will get brainiest

Answers

Answer 1

Answer:

-5.2s - 10.8

Step-by-step explanation:

[tex] \rm \implies 4( - 1.3s - 2.7) \\ \\ \rm \implies - 4 (1.3s + 2.7) \\ \\ \rm \implies - (4 \times 1.3s + 4 \times 2.7) \\ \\ \rm \implies - (5.2s + 10.8) \\ \\ \rm \implies - 5.2s - 10.8[/tex]

Answer 2
-5.2 - 10.8

First you do ( -1.3-2.7) which is -4 and -4 x 4 is -16 and -5.2-10.8 is also -16

-16=-16

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

Subtract 30 from both sides.

This assignment is due soon! If someone can help it would be great. It is about triangle angle sun theorem.

Answers

X = 44 because you set it up like an equation

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.

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
The answer is 95 for this problem

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

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.

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

\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

An art shop has 80 large boxes of markers and 34 small boxes of markers in stock. Each large box contains 48 markers and each small box contains 20 markers.

Which equation could be used to find n, the total number of markers in stock?
A:80 × 48 + 34 × 20= n
B:80 + 48 × 34 + 20 = n
C:80×48−34×20=n
D:80 + 48 + 34 + 20 = n

Answers

The answer would be A
Because if you have 80 large boxes and a large box has 48 makers that would be 80x48 and the same thing for the small boxes which would be 34x20 the you would add both of this to get the total number of makers so it would be 80x48 + 34+20= n

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.
