The ratio of mikes savings to nicks savings was 4: 3 after mike saved another $120 and nick saved another $60 the ratio became 8: 5 what was their combined savings before each of them saved additional money

Mike's savings before he saved additional money = $120

Nick's savings before he saved additional money = $90

Step-by-step explanation:

The ratio of mikes savings to nicks savings was 4:3.

Let their savings be 4k and 3k.

After mike saved another $120 and nick saved another $60, their savings become 4K+120 and 3k+60.

It is given that the new ratio is 8:5.

Therefore,

4k+120 : 3k+60 = 8:5

5(4k+120) = 8(3k+60)

20k+600 = 24k+480

20k-24k = 480-600

-4k = -120

k = 30

So, Mike's savings before he saved additional money = 4k = 4(30) = $120

Nick's savings before he saved additional money = 3k = 3(30) = $90

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}
