Yuki888 [10]

Answer:

The actual distance between the two rivers is <u>232.5 kilometers</u>.

Step-by-step explanation:

GIven:

The scale on a map is 2 centimeters= 50 kilometres.Two rivers on a map are located 9.3 centimeters apart.

Now, to find the actual distance between the two rivers.

Let the actual distance between the two rivers is x.

The two rivers on the map is located apart of 9.3 centimeters.

According to the scale on the map is 2 centimeters = 50 kilometers.

<em>So, 2 centimeters is equivalent to 50 kilometers.</em>

<em>Thus, 9.3 centimeters is equivalent to </em>x.<em />

Now, to solve by using cross multiplication method:

\frac{2}{50} =\frac{9.3}{x}

<em>By cross multiplying we get:</em>

<em />2x=465<em />

<em>Dividing both sides by 2 we get:</em>

x=232.5\ kilometers.

Therefore, the actual distance between the two rivers is 232.5 kilometers.

3) 8p + 7q= 43<br>2p-7=-q<br>I need to solve using substitution. thanks.​
Veronika [31]

Answer:

p=1, q=5. (1, 5).

Step-by-step explanation:

8p+7q=43

2p-7=-q

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

q=-2p+7=7-2p

8p+7(7-2p)=43

8p+49-14p=43

8p-14p=43-49

-6p=-6

6p=6

p=6/6=1

2(1)-7=-q

2-7=-5=-q

q=5

bulgar [2K]

Hey there! :)

Answer:

f(3) = 18.

Step-by-step explanation:

Given:

f(x) = 2x², solve for f(3).

Simply substitute in 3 for x:

f(3) = 2(3)²

f(3) = 2(9)

f(3) = 18.
