Answer:
The answer is 1,200 meters
Step-by-step explanation:
So what I did was find the rate so we want to know how much Sheila can do in just 1 minute first so you would have to do 6,000/ 15 which gives you 400 so he does 400 meters in just 1 minute. So then you would have to multiply 400 by 3 which gives you 1,200, making that your answer.
hope that helped!
Answer:
The equations are:
10x + 9y = 122
x + y = 13
Step-by-step explanation:
Given Jose makes 10$ per hour washing cars and 9$ per hour walking dogs.
Also, it is given that he had worked for 13 hours total making 122$.
Let us assume the number of hours he spent on washing cars = 'x'.
Let us assume the number of hours he spent on walking dogs = 'y'.
Since, the total number of hours is 13, we can write:
x + y = 13 . . . eqn(1)
And since he has made 122$ in total, we will have:
10x + 9y = 122 . . .eqn(2)
'10x' represents the total money earned by washing cars and '9y' represents the total hours spent on walking dogs.
Hence, Eqn (1) and Eqn(2) is the answer.
Solving them will give: x = 5 and b = 8.
Answer:
164 and 287
Step-by-step explanation:
Their difference is 7-4 = 3 ratio units, so each ratio unit must stand for 123/3 = 41.
Then the numbers are 4·41 and 7·41, or 164 and 287.
You did not give us the equation so we can't answer that. Update it and I will try to help.
You basically take out their greatest common factor.
10. 7(2m + 3)
11. 3(3r - 1)
12. 2(5pq + 4p)
