Answer:

35

Step-by-step explanation:

To find this, we are going to use the combination formula as follows;

nCr = n!/(n-r)!r!

In this case, n = 7 and r = 3

Substituting these values;

7C3 = 7!/(7-3)! 3! = 7!/4!3! = 35

The scale on a map shows that 200 miles is represented by 5 inches on a map.Which proportion can be used to find the distance on the map,x, that represents 50 miles?

Answers

If you would like to know which proportion can be used to find the distance on the map that represents 50 miles, you can calculate this using the following steps:

200 miles ... 5 inches
50 miles ... x inch = ?

200 * x = 5 * 50
x = 5 * 50 / 200
x = 1.25 inch

The correct result would be x = 5 * 50 / 200.

Answer:

200 miles over 5 inches = 50 miles over x inches

200/5 = 50/x = 200x/250 =  

x = 250/200 = 1.25

1.25 inches = 50 miles

How many solutions does the following system of equations have?y=5/2x+2
2y=5x+4

One

Two

Zero

Infinitely many

Answers

We will use a method of substitution.
y = 5/2 x + 2 
2 y = 5 x + 4   ⇒  2 ( 5/2 x + 2 )= 5 x + 4
5 x + 4 = 5 x + 4
0 x = 0            ⇒  x, y ∈ R
Answer: D)   
This system has infinitely many solutions.
