Solving the rational equation \frac{3}{x-4}=\frac{7}{x} the value of x is 7

Step-by-step explanation:

We need to solve rational equation: \frac{3}{x-4}=\frac{7}{x} and find value of x.

Solving:

\frac{3}{x-4}=\frac{7}{x}

Cross multiplying:

3(x)=7(x-4)\\Simplifying:\\3x=7x-28\\3x-7x=-28\\-4x=-28\\x=-28/-4\\x=7

So, value of x = 7.

Solving the rational equation \frac{3}{x-4}=\frac{7}{x} the value of x is 7

Alika [10]
Hello!

We know that from midnight to 6am the temperature went up 8° and at 6am it was -21°

To find what it was at midnight we have to work backwards

Since it went up we have to subtract 8 from -21

-21 - 8 = -29

The answer is -29°C

Hope this helps!

Can someone help me?
qaws [65]

Answer:

Your answer is C. 1/2 (16*6) = 48 square feet

Step-by-step explanation:

The formula to find the area of a triangle is A = b*h/2 (base times height divided by half)

First you need to multiply the base (6) by the height (16).

6*16 is 96.

Now you divide 96 by 2 or cut it in half.

96/2 (or cut in half) is 48.

Therefore your answer is C
