Answer:  More infoprmation is needed.  A calculation based on assumptions is provided for guidance.

Step-by-step explanation:

The equation is incorrect.  It is written "d=h/d."  I'll assume d is distance,  If so, the equation shoukld read d = s*t, where s is the speed and t is the time (in the same units as used in s, speed.  We also need to know the Persrverence's speed (e.g, 30 km/hr)

Enter the data and solve for time:  

d = s*t

3,700km = (30km/hr)*(t)  [Using an assumed speed of 30 km/hr)

t = 123.33 hours

6 weeks

Step-by-step explanation:

Set up a proportion where x is the amount of time with 12 pupils:

\frac{4}{2} = \frac{12}{x}

Cross multiply and solve for x:

4x = 24

x = 6

So, it will take 12 pupils 6 weeks to complete the job.

-X + 5 = 1<br> What is the answer for this equation and the steps
jekas [21]

Answer:

x=4

Step-by-step explanation:

-x=1-5 (subtract 5 from both sides to isolate the x variable)

-x= -4 (1-5= -4)

x=4  (divide both sides by -1 so the x will not be a negative.)

Therefore, your answer will be x=4. Hope this helps! :)

GenaCL600 [577]

Answer:

For more;

4.76

for less;

0.46

Step-by-step explanation:

Here, we intend getting the decimals that Carmen should make in her game given the numbers she drew

She has two types to make; a decimal less than 1 and a decimal more than 1

If the decimal should be less than 1, the number zero should lead;

And since she is using three of the numbers, we can have something like;

0.46

To make a decimal more than one, she could actually start with any of the numbers other than zero

we can have something like 4.76
