Find three consecutive even integers with the sum of -84

Let the smallest of the three even integers be x. The next greater even integer is two more than x, so it is x + 2. The next greater even integer is two more than x + 2, so it is x + 4. The three integers are x, x + 2, and x + 4. They add to -84.

x + x + 2 + x + 4 = -84

Now we solve the equation for x.

3x + 6 = -84

3x = -90

x = -30

The smallest of the three numbers is -30.

The next one is x + 2 = -30 + 2 = -28.

The largest one is x + 4 = -30 + 4 = -26

-30, -28, -26

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
