City A and City B had two different temperatures on a particular day. On that day, four times the temperature of City A was 8° C more than three times the temperature of City B. The temperature of City A minus twice the temperature of City B was −3° C. The following system of equations models this scenario:

4x = 8 + 3y
x − 2y = −3

What was the temperature of City A and City B on that day?

City A was 5° C, and City B was 4° C.
City A was 3° C, and City B was −1° C.
City A was 8° C, and City B was −3° C.
City A was 5° C, and City B was −5° C.

Answers

Answer 1

Answer:

City A was 5 and city B was 4

Step-by-step explanation:

Use substitution. Move 2y over so you have x=-3+2y

Plug that into 4x=8+3y

4(-3+2y)=8+3y

-12+8y=8+3y

subtract 3y from both sides

add 12 to both sides

5y=20

20 divided by 5

y=4

then youd plug it into the other equation

x-2(4)=-3

x-8=-3

x=5

therefore the answer is A

Answer:

why you may ask?

subtracted=being taken away from

13 is *being taken away from* x

so if using numbers, 13 is being taken away from 20

or 13 is being subtracted from 20 would be 7, so x-13 would be your expression

Answer:

By using the 90 degree clockwise rotation formula, we are able to determine that the answer is (7, 6)

Step-by-step explanation:

The formula for 90 degree clockwise rotation is

(x,y)--->(y,-x)

The reason why our -6 turns into a positive is because the negative was replacing that negative therefore making it positive.

Hope this helps!

I'll leave the rest of the formulas I have in my notes for you!

180 degree rotations

(x,y)--->(-x,-y)

90 degree counterclockwise

(x,y)--->(-y,x)

270 degree rotation

(x,y)--->(y,-x)

The answer is going to be (7,6)

Answers

Answer:

Let me figure it out rq hold on

how to find the surface area:

The surface area of the triangular prism is the sum total of the areas of its bases and its lateral faces,

736 square feet

We have 2 triangles to add and 3 rectangles.
Area of a rectangle is length x width.
Area of a triangle is 1/2 x base x height.

The top 2 rectangular sides are 20 x 10 = 200 each = 400 total.
The bottom rectangle is 20 x 12 = 240
The triangles are each 1/2 x 12 x 8 = 48, and there are 2 triangles, = 96


Add them all up: 400 + 240 + 96 = 736 square feet

How do you convert mass to volume without density?

Answers

Answer:

Well, you could always just put it onto a scale to find the mass. But assuming you aren't talking about a laboratory setting. sorry if its all werid i cant really put it into how it supposed to be

The general formula is:

ρ

=

m

V

where

ρ

is density in

g/mL

if mass

m

is in

g

and volume

V

is in

mL

.

So to get the mass...

m

=

ρ

V

Or to get the volume...

V

=

m

ρ

When you have the volume and not the density, and you want to find mass, you will need to find the density yourself. It's often readily available on the internet.

Just replace "[...]" with the object you want, and if it's not exactly what you need, consider it an estimate.

These days, you should be able to search for the density of any common object.

When you have the density and volume but not the mass, then just make up a mass.

You shouldn't need specific numbers to do a problem. You can always solve a problem in general and get a solution formula. If you need to, just make up some numbers that you know how to use.
