The sum of two numbers is 981. One of the numbers is 703. What is the other number?
victus00 [196]

Answer:

Other number is 278.

Step-by-step explanation:

Given that

a + b = 981

One of the numbers = 703

We assume that it is a ; So

a = 703

Other number = b = ?

Put value of a in a + b

a + b = 981

703 + b = 981

b = 278

jolli1 [7]

Answer:

5 Laps

Step-by-step explanation:

The question says that she runs the same distance everyday. This shows us that...

2 laps on a running trail and 6 more miles = 4 laps on a running trail and 2 more miles

We can turn laps into the variable L and miles into the variable M to create an equation

2 L + 6 M = 4 L + 2 M

We can start by subtracting 2 M from both sides to get:

2 L + 4 M = 4 L

Now, we can subtract 2 L from both sides

4 M = 2 L

This tells us that 2 laps are 4 miles which means that 1 lap is 2 miles.

Now, we can break down either side of the equation. Let's break down

2 L + 6 M

First, we can turn the miles into laps. We know that 2 miles is one lap so we can divide 6 by 2. Our Equation:

2 L + 3 L

Now, we can simplify this :

5 L

Now we know that she ran 5 laps on saturday.

Hope this Helps!!! :)

Let me know in the comments if this answer was perfect or if I should change anything!!!
