The answer is the number is 3 and the other number is 21. You can set the problem up as two equations. First, x = 1/7y as "a number (x) of 1/7 of another number (y)." Then the difference of the number is 18 is "y - x = 18" because y is the larger of the two numbers from the first equation. You could then substitute 1/7y for x in the second equation and solve for y, which is 21. You can then solve for x, the number, or 3.
Answer:
Option B, 3 over 8
Step-by-step explanation:
<u>Step 1: Make an equation</u>
1/4 * 3/2 = a
3/8 = a
Answer: Option B, 3 over 8
The slope is -4/5 but in standard form it would be 4x-5y=30.
Answer:
70 cars per year.
Step-by-step explanation:
Given:
In 1984 a locally-owned car company sold 2,743 cars.
In 2003, the car sales rose to 4,069.
Question asked:
What was the average rate of change for the total number of cars sold?
Solution:
In 2003 number of cars sold = 4069
In 1984 number of cars sold = 2743
Change in the number of car sold = 4069 - 2743
= 1326
Now, time interval between 2003 and 1984 = 19


Thus, the average rate of change for the total number of cars sold is 70 cars per year.
