i need help. i am confused.

Answer:

x=8

Step-by-step explanation:

Each of the angles in a rectangle equal 90, so you would set 10x+10 equal to 90.

10x+10=90

10x=80

x=8

Answer:

I think it's 11

Step-by-step explanation:

11 times 3 is 33 minus 8 is 25 and 25 is greater than 22

Answer:

h > 10

Step-by-step explanation:

3h-8>22

1. Separate the coefficient and variable.

Separate 3h, we'll save that for later.

2. Use inverse operations and apply it to both sides of the equation.

In this case, it is subtraction, so we will add 8 to both sides of the equation.

3h - 8 > 22

    + 8   + 8

That gives us 3h > 30, because the 8 and 8 cancels out.

3. Use inverse operations. (3h and 30.)

In this case, it is multiplication, so we will divide 3 from both sides of the equation.

3/3 > 30/3

30 divided by 3 is 10, therefore, the answer is h > 10

(Since we did not divide 30 with a negative number, the sign stays the same, and it is not switched.)

Answer:

Step-by-step explanation:

Slope is the difference in y values over the difference in x values

another way to look at it is [tex]\frac{rise}{run}[/tex]

If the slope is 0.28, that means that

[tex]rise = 0.28(run)[/tex]

We're told that the section rises by 1 unit

[tex]1 = 0.28(run)\\[/tex]

[tex]run = \frac{1}{0.28} = 3.571428571 = 3.57[/tex]

Answer:

-8.4,-8,8,8.4

Step-by-step explanation:

Answer:

Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Thus, the equation of the line is y = ½x + 6.

Answer:

See below.

Step-by-step explanation:

This question makes no sense.

Here is the question. Pay attention to the words in boldface.

"In order to write the equation of the line passing through the point (-2, 2) that is parallel to the line y = 2x + 3 , the next step is to find the y-intercept of the perpendicular line. What is the y-intercept of the perpendicular line through point (-2, 2)?"

Is the question asking for the parallel line or the perpendicular line?

Answer:

Work shown below!

Step-by-step explanation:

White bead = [tex]\frac{5}{15} =\frac{1}{3}[/tex]

Answer:

a 33.3333333% chance

Step-by-step explanation:

we do 7+3+5= 15 (the denominator)

and so the amount of white beads in total is 5/15

5÷15+100= 33.333333333 and so on percent

Answer:

(-8) + (-8) + (-8) + (-8)

Step-by-step explanation:

Since Yan is descending ; we represent his movement as being negative.

Number of rungs descended before stopping = 4

Number of stops = 8

Given that no extra steps was taken ;

Number of ladder rungs descended :

4 rungs per stop for 8 stops

- 4 * 8 = - 32 rungs

Another way to write the product :

Number of stops added in number of rungs descended :

(-8) + (-8) + (-8) + (-8)

Answer:

8,748

Step-by-step explanation:

f(x) = [tex]12(3)^{x}[/tex]

f(6) = [tex]12(3)^{6}[/tex] = 12 × 9³ = 12 × 729 = 8,748

Step-by-step explanation:

divide the 42 gallons by 3 (since 3 seconds for 42 gallons) to find the rate of change. the answer is 14. then just do the number times 14 all the way. and yes this is proportional

Answer:

-8x-21=3y or -8/3x-7=y or 8x+y+21=0

Step-by-step explanation:

First find the slope of 3x-8y=16.

3x-16=8y (divide both sides by 8 so that y is isolated)

3/8x-2=y The slope is 3/8. The perpendicular slope is the negative reciprocal of 3/8, which is -8/3

Using the points, the equation of the line can be found.

(-8/3=y-1/x-(-3))3(x-(-3) (3(x-(-3) is the common denominator

This equals -8x-24=3y-3, add three to both sides which equals -8x-21=y.

The other answers are written in slope y-intercept form and general form.

*Note: x-(-3) can be written as x+3

Answer:

x=6.25

Step-by-step explanation:

What you do is add up all the angles equal to 180 because a triangle always adds up to 180 degrees and you are given all angles.

Answer:

x = 25/4

General Formulas and Concepts:

Pre-Algebra

Geometry

Step-by-step explanation:

Step 1: Set up equation

(22x + 1)° + (6x - 17)° + (4x - 4)° = 180°

Step 2: Solve for x

Answer:

[tex]p=39.4[/tex]°

Step-by-step explanation:

[tex]4a+4+75+p=180[/tex] (The sum of angles on a triangle is [tex]180[/tex]°)[tex]4a+p=180-4-75[/tex]

[tex]4a+p=101[/tex]

[tex]p+9a+2=180[/tex]  (Angles of a straight line sums to [tex]180[/tex]°)

[tex]p + 9a = 178[/tex]

Elimination can be used to find the value of one variable:

[tex]p+9a-(4a+p)=178-101[/tex]

[tex]5a = 77[/tex]

[tex]a=15.4[/tex]

Now, the value of [tex]p[/tex] can be found by using substitution:

[tex]4a+p = 101[/tex]

[tex]4(15.4)+p=101[/tex]

[tex]p = 101-61.6[/tex]

[tex]p = 39.4[/tex]

Answer:

12 years

Step-by-step explanation:

Given that Mr. Hon purchases a new car every 4 years. Ms. Jasper purchases a new car every 6 years.

Assuming that they purchase new cars together after n years.

So, n must a multiple of 4 as well as multiple 6, i.e the number n is the lowest multiple (LCM) of 4 and 6.

As LCM od 4 and 6 is 12, so n=12.

Hence, after 12 years they will purchase news cars together.

Answer:

iam sorry but furries are good lg!!!

Furry can have two definitions. A furry is either an anthrophomorphic animal which has human characteristics or a person that shows interest in furries. If you draw other people's fursona, i don't think that makes you a furry tbh. If you show interest and if you have your own fursona and you're passionate about it, however, then yeah you're pretty much a furry. Being a furry isn't bad honestly, it's just a hobby. I'm a furry myself and i honestly love this fandom. I met a lot of great people!

Answer:

90

Step-by-step explanation:

The number of candies can be divided among 2, 3, or 5 children so that is the same as saying: the number of candies must be divisible by 2, 3, and 5. In order for a number to be divisible by 5, it must end in 0 or 5 so we know the number of candies must end in 0 or 5. For a number to be divisible by 2, the number must end in an even number. 5 is not an even number so we know the number of candies must end in 0. If a number is divisible by 3, the digits added are divisible by 3. Go through each number(80, 90, 100) and see which one is divisible by 3. 90 is divisible by 2, 3, and 5.

Proof that 90 is divisible by 2, 3, and 5:

90 ÷ 2 = 45

90 ÷ 3 = 30

90 ÷ 5 = 18

The results are all whole numbers.

_____

0.51

5+6=11

3+2=5 I said 2 because 5+6=11 so you had to carry your 1

then you would just bring your 0 down cause everybody know 0+0=0 lol!
