Let x be the unknown number. One fifth of this number is x/5, one fourth of this number is x/4. So, we have
We know that this difference equals 9, so we have
Multiply both sides by 20 to get
Congrats to Shirley!! Does she have a question?
Answer:
<em>The ordered pair is (4,6)</em>
Step-by-step explanation:
<em>Ordered Pairs</em>
It's given the equation
y = x + 2
Since there are no restrictions for the values of x and y, it has infinitely many solutions, i.e. any ordered pair of values (x,y) that make true the equation is a solution.
We can pick any value for x and then calculate the corresponding value for y as follows:
For x = 4,
y = 4 + 2 = 6
The ordered pair is (4,6)
(1,-2) hope this helps you :)
Answer:
Division property get you to the quick solution
Solution: 3.4
Step-by-step explanation:
5*(x - 2) = 7
Dividing both sides by 5
5*(x -2)÷5 = 7÷5
x - 2 = 1.4
Adding 2 on both sides, we
x -2 + 2 = 1.4 + 2
x = 3.4
Hope you will understand the concept.
Thank you.
