Answer:

Step-by-step explanation:

Let the original number = x

$x+\frac{8.2}{100}*x=106\\\\x+0.082x=106\\\\1.082x=106\\\\x=\frac{106}{1.082}\\\\x=\frac{106*1000}{1.082*1000}\\\\x=\frac{106000}{1082}\\\\x=97.96\\\\$

x=98.0

x=98

Answer:

Required equation is: 25n = 875

Step-by-step explanation:

Let n be the number of minutes Jonathon read per day

Now

He read for 25 days and total 875 minutes

The equation will be:

$25n = 875$

We can solve this equation to find the number of minutes each day

Using Division property of Equality

$\frac{25n}{25} = \frac{875}{25}\\n = 35$

Hence,

Required equation is: 25n = 875

Answer:

-9 = 0.45m

Step-by-step explanation:

$0.45m - 9 = 0.9m$

^ Subtract 0.45m from BOTH sides. so $0.9m - 0.45m$ ... etc
Why? So that we can make the equation less complicated. Our goal is to isolate the variable m to be on one side of the "=" sign by itself
That will equal to:

$-9 = 0.45m$ <-- ANSWER
