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

A rhombus has sides of length x + 6 inches and a perimeter of 49 inches. Which equation represents this situation?​

Answers

Answer:

a

Step-by-step explanation:

The equation representing this situation is 4( x + 6 ) = 49.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that a rhombus has sides of length x + 6 inches and a perimeter of 49 inches.

The equation can be written as,

4 ( x + 6 ) = 49

The perimeter is given as,

4 x side = perimeter

4 x ( x  + 6 ) = 49

4 ( x + 6) = 49

C. y=x+1

Step-by-step explanation:

The formula for slope is rise over run, or rise/run. This means that you take the amount a line rises (or decreases) between 2 points. The run is the distance on the x-axis (___ looking line) that separate the two points. The y-intercept is going to be the point that is on the y-axis, the vertical line (| looking line). To find the equation, you take the slope, multiply that to x, and add the y-value of the y-intercept.

Step-by-step explanation:

(2x + 9)(x+3)

2x² + 6x + 9x+ 27

2x² + 15x + 27

Answer:

2x² + 15x +27

Step-by-step explanation:

Using FOIL:

⇒ 2x * x = 2x²

⇒ 2x * 3 = 6x

⇒ 9 * x = 9x

⇒ 9 * 3 = 27

It would add up to; 2x² + (6x + 9x) +27 and simplifying the parenthesis would simplify to 2x² + 15x +27.

Can someone please help me find the sum of each interior angle measure of the polygon, and can you please explain. I need help on both of these questions.

Answers

Answer:

I'm sorry I have no clue what this is. What grade are you in? I'm in seventh and  I have never learned anything like this lol.

Step-by-step explanation:



3)first you count the sides
There are 8 sides

The equation of of finding the sum of all the interior angles is (n-2)*180
(8-2)*180
=6*180=1080

To find the measure of one interior angles divide the answer by the number of sides
900/8=112.5



4)first you count the sides
There are 7 sides

The equation of of finding the sum of all the interior angles is (n-2)*180
(7-2)*180
=5*180=900

To find the measure of one interior angles divide the answer by the number of sides
900/7= 128.57
