Answer:

80 degrees i believe

Step-by-step explanation:

if supplementary angles =180 then 180-100=80

Answer:

m∠QRS = 80°

Step-by-step explanation:

We know that, sum of supplementary angles is 180°.

Given that ∠ABC and ∠QRS are supplementary, and m∠ABC = 100°.

So, m∠ABC + m∠QRS = 180°

=> 100° + m∠QRS = 180°

=> m∠QRS = 180° - 100°

=> m∠QRS = 80°

Answer:

C

Step-by-step explanation:

It is not A, that implies that there is no parenthesis needed. Same goes for D.

It is not B, (5x +2)-3

"Three less than" implies that 3 will be subtracted in the end of the equation.

B and C may get mixed up: C includes the phrase "the quantity" which implies the number (x) and two are added before being multiplied by 5.

hope this will help u

Step-by-step explanation:

I hope it will help you so .

Hello!

First:

write an equation.

5x + (7x+8) + (7x+2) = 143

now combine like terms

19x + 10 =143

now subtract 10 from both sides

19x = 133

divide 19 on both sides.

x = 7.

Are you done here? Nope, we need to find out what each side is, so lets plug in the number 7 for x.

-----------------------------

For the side 5(x)

5(7) = 35

This side is 35m

-----------------------

For the side 7x + 2

7(7) + 2

49 + 2

51

This side is 51m

------------------------

For the side 7x + 8

7(7) + 8

49 + 8

57

This side is 57m.

------------------------

I hope this helps,

Have a great day!

Step-by-step explanation:

Y2-y1/x2-x1

The slope of the given line is m = 4.

Given,

Point A has coordinates (-6, -2).

Point B has coordinates (-4,6).

We need to find what is the slope of a line segment connecting the two.

If the two points are (x_1, y_1) and (x_2, y_2).

Then the slope is given by:

m = (y_2 - y_1) / (x_2 - x_1)

Find the slope.

Let,

(-6, -2) = (x_1, y_1)

(-4, 6) = (x_2, y_2)

m = (y_2 - y_1) / (x_2 - x_1)

m = (6 - (-2)) / (-4 - (-6))

m = (6 + 2) / (-4 + 6)

m = 8 / 2

m = 4

Thus the slope of the given line is m = 4.

Answer:

402 + 39 = 441

Step-by-step explanation:

Counting on means that you start with the biggest number and then count up from there. -hopefully this helped.

The solution is 441

The value of the equation A = 402 + 39 is A = 441

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

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

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the first number be x = 402

Let the second number be y = 39

The equation A = first number + second number

Substituting the values in the equation , we get

A = 402 + 39

On simplifying the equation , we get

A = 441

Therefore , the value of A is 441

Hence , the value of the equation is 441

The least common multiple can be used to find the smallest square formed by equal sized shapes

The least number of tiles to be used is 15 tiles

The arrangement of the tiles, with the 6 inch side as base is 3 rows by 6 columns of tiles

The reason the above responses are correct is as follows:

The unit area of each square tile = 6 inches by 10 inches

Therefore, the area of the square obtained is a factor of 6 × 10 = 60 in.²

The side of the square have 6 and 10 as factors

The lowest common multiple of 6 and 10 is 30

Therefore, the smallest square has a side length of 30 inches and an area of 30 in. × 30 in. = 900 in.²

The least number of tiles = Area/(The area of each tile)

Therefore, the least number of tiles = 900 in.²/(60 in.²/tile) = 15 tiles

The least number of tiles = 15 tiles

The arrangement of the 15 tiles are as follows;

With the 6 inch width side as the base, five tiles are arranged along the base, three more rows are constructed using the same process to form the 30 inch by 30 inch square to give 3 rows by 6 columns of tiles

===========================================================

Explanation:

Let's say we want to solve the equation h = 54 + 10a for the variable 'a'. This is relevant to the problem at hand don't worry.

What we'd do is two things

So the steps look like this

h = 54 + 10a

h-54 = 10a

(h-54)/10 = a

a = (h-54)/10

Now let's say we wanted to solve this equation: h = 54 + ca, where c is a constant and can stand in place of any number. The steps would be pretty much identical. Instead of dividing both sides by 10, we divide both sides by c. We can do this as long as c isn't zero of course.

That means the equation h = 54+ca solves to a = (h-54)/c

---------------------------

Why did I do those examples? To build up to the equation your teacher gave you.

Let's replace c with 0.5t^2

This is because 1/2 = 0.5

The 1/2at^2 is the same as (1/2t^2)a

So instead of a = (h-54)/c, we'd get a = (h-54)/(0.5t^2)

As a last optional and encouraged step, we can multiply every term by 2 to get rid of that decimal value.

Doing so makes a = (h-54)/(0.5t^2) turn into a = (2h-108)/(t^2)

---------------------------

Here's another way to solve:

h = 54 + (1/2)at^2

h-54 = (1/2)at^2

2(h-54) = at^2

2h-108 = at^2

(2h-108)/(t^2) = a

a = (2h-108)/(t^2)

In the second step, I subtracted 54 from both sides. Immediately afterward, I multiplied both sides by 2 so I could clear out the fraction. Then I divided both sides by t^2 to fully isolated the variable 'a'.
