Answer:
Equations with one solution:
Equations with no solution:
Equations with infinite many solutions:
Step-by-step explanation:
We will solve each equation to see if it has one solution, no solution or infinite many solutions.
An equation where the value of variable can be found has one solution.
An equation with no solution has both sides different.
An equation with infinite solution will have both sides equal after solution(number)
So,
<u>Equation 1:</u>
5(x-2) = 5x-7
As both sides are not equal, equation has no solution.
<u>Equation 2:</u>
As both sides are equal the equation has infinite many solutions.
<u>Equation 3:</u>
As x=3, the equation has only one solution.
<u>Equation 4:</u>
The equation has no solution.
Hence,
Equations with one solution:
Equations with no solution:
Equations with infinite many solutions:

Step-by-step explanation:
For better understanding, I'll make use of an attachment.
From the attachment,
O represents the start point
--- Jack
-- Distance between them
Required
Find OA; Jack's distance
To do this, we make use of Pythagoras theorem
This gives:
Subtract 900 from both sides
Take square roots
<em>Hence, Jill drove 72 miles</em>
