The formula for speed is distance divided by time. 300/25=12. Therefore, the average speed is 12 meters per second.
Answer:
Zach earns $10 and for the pair of boots Zach earns $15
Step-by-step explanation:
Let be x the number of pairs of shoes
Let be y the number of pairs of boots
Then we can establish the following system of equations with the data of the statement:

We subtract the second equation from the first equation to eliminate the variable y and solve for x, just like this:

For y replacing in the first equation the value of x and solving for y:

So for the pair of shoes Zach earns $10 and for the pair of boots Zach earns $15

Answer:
step 1: x+50+4x=90
the angle of a right-angled triangle is 90 degrees, therefore if we add everything together ,we could work out what x is.
step 2: x+50+4x=90
x+4x=50
5x=50
x=10
then you solve the equation, x is 10
Total length of the garden row = 6 meter
Since, 6 meter garden row is divided into 4 equal seized sections to plant onions.
We have to determine the equation which determines the number of meters in each section.
Let 'm' be the number of meters in each section of the garden.
So, the equation is:

This equation represents the number of meters in each section.
