Noori, this is a multi post from a while ago:

I had a feeling I wasn't the only one...

It was there a few weeks ago...

Yep.

1. How many numbers between 0 and 120 are a multiple of 7? [17]

2. How many multiples of 7 are between -120 and 0? [17]

3. How many multiples of 7 are in 0? [1]

4. Add them all together: [35]

Do you know the number of hours in a day? Good. It's 24. We want to do modular arithmetic, so here it is:

1. How many times does 2025 go into 24? Do the calculation and tell me the remainder. Highlight this for the answer to this part: [84 R9]

2. Take the remainder and add it to the current time (5pm). This gives us: [9+5=14=2am]

3. Thus it will be [2 am] 2025 hours from now.

(Highlight the area between the brackets to see the answer to each step.)

Complementary angles add to 90 degrees.

Supplementary angles add to 180 degrees.

Now that you know this, try to solve the problem. If you want a step-by-step, reply to this thread and I will happily walk you through it.

That is kinda sad.

Have you learned Vieta's formula yet? You could really use it here. 

\(\text {root}_1 + \text {root}_2 = 5\\\text {in your situation. Vieta's formula says that this will be equal to} \\-\frac ba \\\text {where }b=-M \text { and } a=x \text { in your case}\)

So this gives us \(-\frac {-M}x = 5 \\\implies \frac Mx = 5 \\\implies \mathbf {M = 5x}\)

So M=5x. 

Try to solve the equation now that you know this.
