Answer:

12t -3 = 18t

Step-by-step explanation:

Let

d = your friends distance in miles

t = time in hrs

Your equation:

d - 3 = 18t (1)

Because you are 3 miles behind your friend

Your Friend's equation:

d = 12t (2)

To find the amount of time t it takes for you to catch up with your friend,

Substitute (2) into (1)

d - 3 = 18t

12t - 3 = 18t

Equation to find the amount of time t it takes for you to catch up to your friend is 12t - 3 = 18t

Solving the equation

12t - 3 = 18t

Collect like terms

12t - 18t = 3

-6t = 3

t = 3/-6

= -0.5

t = 1/2 hour

Time can not be negative, therefore it will take 1/2 an hour to catch up with your friend

What expression is equivalent to 7sqrtx^2/5sqrty^3​
V125BC [204]

Answer:

Step-by-step explanation:

Sounds as tho' possible answer choices were listed.  Please, share them without being asked to do so.  Thank you.

 7√(x²)          7√(x²)

------------- = ----------------------

  5 √(y³)        5√( y^(3/2) )

We want to get the fractional exponent out of the denominator.  To do this, multiply both numerator and denominator by y^(1/2):

 7√(x²)          7√(x²)                y^(1/2)      7√(x²)·y^(1/2)       7x√y

------------- = --------------------- * ----------- = --------------------- = ----------

  5 √(y³)        5√( y^(3/2) )       y^(1/2)        5 √(y²)                  5y

This is the final answer.  We have succeeded in removing radicals / fractional exponents from the denominator.

What is the answer to <br> x to 50 and 16 to 25<br><br> A.32<br> B.34<br> C.41
GuDViN [60]

Answer:

A.32

Step-by-step explanation:

We can write a proportion to solve this problem

x           16

------- = ----------

50          25

Using cross products

x*25 = 16*50

Divide each side by 25

25x/25 = 16*50/25

x = 16*2

x = 32
