14. The sum of the digits of a certain two-digit number is 4. When you reverse its digits you decrease the number by 18. What is
kipiarov [429]

Step-by-step explanation:

If the tens digit of the number is X and the ones digit is Y then the number is equal to 10*X + Y

If you reverse the digits then the number is equal to 10*Y + X

If reversing the digits decreases the number by 36 then

10*Y + X = 10*X + Y - 36

The sum of the digits is 4 so X + Y = 4 ==> X = 4 - Y

Substitute this value of X into the 1st equation

10*Y + (4 - Y) = 10*(4 - Y) + Y - 36

9*Y + 4 = 40 - 9*Y - 36

18*Y = 0

Y = 0

I hope it helps you

So X = 4 - 0 = 4 and the number is 40

so, let's check 40 - 04 = 36

A forest fire covers 2006 acres at time t equals 0. the fire is growing at a rate of 8 startroot t endroot acres per hour, where
MissTica
<span>Answer: We'll have to integrate the growth rate with respect to time, without forgetting the amount of area covered at the start. A = 2010 + â« 8t1/2 dt (as t goes from 0 to 24) A = 2010 + [(16/3) t3/2] (as t goes from 0 to 24) A = 2010 + 627 = 2637 acres We don't integrate the 2010 here because whatever effects of the passing of time have already taken place over that area. We just treat it as a constant and add it to the result of integration.</span>

Show your work and explain in a full sentence how 4 2/6 is equivalent to 3 8/6
Naddik [55]

Answer:

Multiply the whole numbers by their denominators and then add the product to their numerators. You will notice that they equal the same improper fraction.

Step-by-step explanation:

4 * 6 = 24.

24 + 2 = 26.

4 2/6 as an improper fraction equals 26/6.

3 * 6 = 18.

18 + 8 = 26.

3 8/6 as in improper fraction equals 26/6 as well.

So that is how they are equivalent.
