Explain this step by step and solve within 10-20 minutes

is the answer.

In decimal y = 43.71

Step-by-step explanation:

Given:

y varies directly with x .

Also x = 7 when y = 18

To Find:

y = ? when x = 17

Solution:

y varies directly with x .

i.e. y is directly proportional to x

∴

Where

k = constant of proportionality {Remain Same}

First we will find constant of proportionality k,

∴ When x = 7 and y = 18 we have

∴

Now when x= 17 and we have

∴

∴

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
