Answer:

Mark has 23 marbles, Don has 74 marbles

Step-by-step explanation:

Mark has x marbles, Don has y marbles

y = 5 + 3x

x + y = 97

so

x + (5 + 3x) = 97

4x = 97 - 5 = 92

x = 92/4 = 23

y = 97 - 23 = 74

Simplify the expression. 19m – 4m2 + 4m2
solmaris [256]
I am not sure what does that question mean by simplify. If it means not to solve and just arrange;
You can divide the whole of the equation to m^2

Then you get;
19/m -4 +4

And you can divide the whole equation to 4 then you get;

19/4m -1 +1

You can also write as ;
(1/m * 19/4) - 1 + 1

How do you find the percent of increase from 12 to 18?
olga nikolaevna [1]
Let's get the data out of the problem:

Nv = 18

Ov = 12

Now, we can apply in this equation that relates the new and the old values:

i = Nv / Ov

i = 18 / 12

i = 1.5

Now, we just consider what has passed from 1, and this is 0.5, converting to percentage it is:

p = 0.5 . 100

p = 50%

The increase was 50%.

Hope it helps.
