The sum of 5 times one number, x, and 4 times a second number, y, is 75. If the sum of the two numbers is 18, find the two numbe
satela [25.4K]

Answer:x=3 and y=15

Step-by-step explanation:

First, we are told "sum of 5 times one number, x, and 4 times a second number, y, is 75":

5x+4y=75 (1)

Then, we are told "he sum of the two numbers is 18":

x+y=18 (2)

At this point we have our system of equations and now we are able to find the values of x and y.

So, let's begin by isolating x from (2):

x=18-y (3)

Substituting (3) in (1):

5(18-y)+4y=75 (4)

Finding y:

90-5y+4y=75

y=15 (5) This is the value of y

Substituting (5) in (1):

5x+4(15)=75 (6)

Finding y:

5x+60=75 (7)

x=3 (8) This is the value of x

How many different 4 color code stripes can be made on a sports car if each code consists of the colors green, red, blue, and wh
Akimi4 [234]
From the list of colors: green, red, blue, and white, there are four colors. The concept that should be used in order to determine the number of 4-color code stripes that can be drawn in the sports car is the concept of BASIC PRINCIPLE OF COUNTING.

The equations that would best help us in answering the question is,
                         n = 4! (that is, four factorial)
For the first pick, there are four choices. When one is already used then, there are only 3 choices for the second color, and so on until the last color. 
                         n = 4 x 3 x 2 x 1 = 24
Thus, there are 24 types of 4-color codes.
