Answer:

22(c)

Step-by-step explanation:

Our current proportion is

15 miles

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

1 hour

We need feet per second.

Lets convert!

15 miles= 79200 feet(used googl to find this)

1 hour=3600 seconds(also used googl to find this)

( i know its not spelled that way brainly wont let me write the whole word out)

Now, our proportion is:

79200 feet

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

3600 seconds

HOWEVER, this can be simplified!!!!

79200/3600=22

Final answer: 22, or C.

a system of equations is graphed here. which system of equations does the graph represent? A) y = 3x + 2y = -2x + 5 B) y = 3x -

n200080 [17]

Notice that the line with negative slope has a y-intercept of 5 and the line with positive slope has a y-intercept of 2.

On the other hand, the slope of the line with negative slope is -2, while the slope of the line with positive slope is 3 (This can be identified since in one case, the value of y decreases by 2 for each increase of 1 unit in x, and in the other, the value of y increases by 3 for each increase of 1 unit in x).

Using the y-intercept form to represent each line, the system of equations represented by the graph must be equivalent to:

$\begin{gathered} y=-2x+5 \\ y=3x+2 \end{gathered}$

From the given options, the one that displays the correct system of equations is option A.

Therefore, the answer is:

$\begin{gathered} A) \\ y=3x+2 \\ y=-2x+5 \end{gathered}$

Answer:

$3(x + 2) = 2(x + 2) \\ 3x + 6 = 2x + 4 \\ 3x - 2x = 4 - 6 \\ x = - 2$

Matti built a greenhouse in his backyard as shown below

Vanyuwa [196]

well, Matti's house is a triangular prism, and to get the volume of it, we simply get the area of the triangle upfront and multiply by its length of 15.

$\bf \stackrel{\stackrel{\textit{area of }}{\textit{triangular front}}}{\cfrac{1}{2}(7)(7)}\times \stackrel{\textit{length}}{15}\implies \cfrac{49}{2}\cdot 15\implies 367.5~ft^3$

How man 1/3 cups make 3/4 cups

Sati [7]

Answer:

it would take 2.25 1/3 cups if you are looking for an exact answer, or if you are looking for the minimum amount of 1/3 cups necessary to make 3/4 it would be 3.

Step-by-step explanation:

You can solve this by cross multiplying 1/3 and 3/4

You will get 9/4 which simplifies to 2 1/4 or 2.25
