Why does the sum of the two given angles equal 180°? (2x+1)+(x-7)=180

Answers

Answer:

because its a straight line

Step-by-step explanation:

Answer:

Since the sum of the angles is 180 degrees and each angle is represented by the respective algebraic expressions, then to find the value of x, just add the expressions up, set that sum equal to 180, and solve for x. So, (2x-7)+(x+25)+(3x+12)=180 is our equation. Now we just simplify and solve for x.

(2x-7)+(x+25)+(3x+12)=180

6x+30=180 b/c 2x+x+3x=6x and -7+25+12=30.

6x=150 subtract 30 from both sides of the equation

x=25.

Dracula jumped 5 times every 30 minutes at that rate, how long,in minutes will it take to jump 6 times?

Answers

Answer:

36 minutes

Step-by-step explanation:

If I read this correctly, Dracula jumps 1 time every 6 minutes. If he jumped 5 times in 30 minutes, then that means when he jumped a sixth time, it was 36 minutes that passed since:

30 / 5 = 6

So, if he were to jump a sixth time:

30 + 6 = 36

Therefore, Dracula jumps 1 time per 6 minutes.

Ok this is pretty simple. Slope intercept is by far the most simple way to write an equation given that it only has 2 pieces: the slope of the line and the value at which it crosses the y axis (so when x=0). Slope is usually represented by the varriable "m" and the y intercept is usually represented by the letter "b". (Don't ask me why they chose these 2 random letters. It's... it's just whatever... Go with it.) Thus, we have the equation y=mx+b. So anyways.. Slope is just the change in y divided by the change in x. To find this, we just take 2 random points on the graph, subtract the first y from the second y and divide that by the first x subtracted from the second x. Let's use (2,-9) and (4,-10) from this fun little graph you ever so generously provided for us.

I'm bad at transitions so here's the math:

(y2-y1)/(x2-x1)

((-10)-(-9))/(4-2)

-1/2 ------> Thats "m".

SOOO... the slope is -1/2. Cool. BUT WE ARENT DONE

The other thing we need is the y-intercept. You may find yourself asking "what is this... this THING... he speaks of?" Its where the line hits the y axis. Thats is. It's not that hard. In this case it's -8 so b=-8.

Now for the best part... LETS PLUG ALL THOSE DOOHICKEYS IN.

y=mx+b

m=-1/2

b=-8

y=-1/2x+-8-----> y=-1/2x-8

For the 6th annual school fundraiser, Daisy needs to sell 38 rolls of
wrapping paper. So far, she has sold 2.24 rolls to her grandmother, 5.75
rolls to her uncle, and .6 rolls to a neighbor. How many more rolls of
wrapping paper does Daisy need to sell? If each roll costs $3.46, how
much money can Daisy make?

Answers

Answer:

She needs to sell the rest of her 29.41 rolls of wrapping paper. If she sells all of her rolls of wrapping paper, she'll be able to get a total of $131.48.

Step-by-step explanation:

To get the answer to "How many more rolls of wrapping paper does Daisy need to sell?" you would have to add up how many she already sold which is

2.24 + 5.75 + 0.6 = 8.59

and then subtract 8.59 from the total of rolls she's supposed to sell.

38 - 8.59 = 29.41

To get $131.48

You multiply how much each roll costs to the total of rolls she's supposed to sell:

38 * 3.46 = 131.48

Hope this helped :)

1. 3 feet is equal to 36 inches if you divide 36 by 4 you get 9

Step-by-step explanation:

2. 5 yards by 3 feet per yard equals 15 feet of fabric

Don't try to cheat the system by asking so many questions in 1 block

Question 1. if 3 flowers = 4 inches, and she has a 3 foot long row to plant flowers, then we need to see how many inches the row is.

1 foot = 12 inches

12 inches x 3 = 36 inches, or 3 feet.

Now we need to divide.

36 divided by 4 = 9.

So now we know that Mrs. Ryan can plant x amount of flowers 9 times. This makes the answer easier to find.

To find the answer, we need to simply multiply 3 and 9.

3 x 9 = 27.

Your answer would be Mrs. Ryan planted 27 flowers.

Question 2. this is simple. Just multiply 5 and 3.

5 x 3 = 15.

Your answer would be Mrs. murphy bought 15 feet of fabric.

Question 3. This is simple...Just multiply 4.3 x 100, or move the decimal over to the right twice and put a 0 where theres an empty space.

4.3 x 100 = 430

Your answer is the line is 430 centimeters wide.

Question 4. This is simple, just multiply 2.9 x 100 or move the decimal over to the right twice and put a 0 where there's an empty space.

2.9 x 100 = 290

Your answer is The book is 290 milliliters wide.

Question 5. This is also very simple. This time we add a decimal twice to the left. Put the decimal next to the 0 in 210.

210.

21.0

2.10

Your answer would be the bookshelf is 2.1 meters tall.

Question 6. This is, again, simple... Just multiply 3 and 1.61.

3 x 1.61 = 4.83

Your answer would be Connor ran 4.83 kilometers.

Question 7. This is simple, again... Just multiply 13 and 2.54.

2.54 x 13 = 33.02

Your answer would be c, 33.02 cm.

Which equation has a constant of proportionality equal to 7?
A. 4y = 28x
B. 7y = 28x
C. 28y = 4x
D. 28y = 7x

Answers

A is correct.

Reasoning: 4 x 7 = 28


good luck!

The solution is Option A.

The equation which has a constant of proportionality k = 7 is 4y = 28x

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the equation be represented as A

Now , the value of A is

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

Now , the equation is

4y = 28x

On simplifying the equation , we get

Divide by 4 on both sides of the equation , we get

y = 28x/4

y = 7x

y = 7x is of the form y = kx where the value of k is 7

Therefore,  the value of k is 7

Hence , the value of proportionality constant is 7

What is mean and median?

"The mean is the number you get by dividing the sum of a set of values by the number of values in the set.

The median is the middle number in a set of values when those values are arranged from smallest to largest."

Mean for grade 6 is

= [tex]\frac{1+2+3+1+1+1+1}{7}[/tex]

= [tex]\frac{10}{7}[/tex]

Mean for grade 7 is

= [tex]\frac{1+2+5+2}{4}[/tex]

= [tex]\frac{10}{4}[/tex]

From both we get, Mean is greater for grade 7

Median for grade 6 is 1

Median for grade 7 is

= [tex]\frac{2+5}{2}[/tex]

= 3.5

From both we get, Median is greater for grade 7
