Where the answer is equal to M?
It should be able to be solved by a 7th grader in America (12-13)

And no, this is not my homework.

I have no idea what you guys learn in Grade 7 in America...

uh.

3m x 82 - 9m = (8+13) / 7 x 1000

This is probably too hard...

But can anybody solve it? It's relatively easy for these kinds of questions!

Highlight below to see the answer.
m=61

How hard?

Easy(ish)
3^5+3=?

Medium(ish)
(23+5^2)-6=?

Hard(ish)
2.15*3(8/2^2)-7=?

In general equations? Are we talking about slope-intercept form? I need some clarification.

Anything you learned in Grade 7 which involves 'm'

Something that wouldnt look retarded in a letter.

M? Isn't M slope?

That made me confused even more. I have a basic algebra problem.

Write the line perpendicular to the equation y=-2x + 5 1/2.

Do not blame me I am more confused than a second grader on this problem.

y=-1/2x + 5*1/2.

The last part of your problem is 5 multiplied 1/2, right?


Pretty much means you flip the top and bottom number and then multiply the answer by negative 1. (That flips the sign.)
For example:
-2/1 -> 1/2
3/5 -> -5/3


And I hope you know that a whole number is just that number over one.
2=2/1

Solve for m:

y=2m + 2(8-7)

M= the square root of 29. Do this w/out a calculator. Have fun

This equation is solved in the following manner:

y=-2x + 5 1/2
1.) y=1/2x
Perpendicular slopes are the reciprocal multiplied by negative one. The y-intercept could be anywhere on the y-axis, for it is perpendicular either way.



This was more of a common sense problem; one could make it more difficult by making the line pass through two points, forcing one to first put the equation in point-slope form: y – y1=m(x-x1). Maybe you misread the problem, or perhaps I provided too little in context.

1. I got 246

2. I got 42

3. I'm stuck at 12.9 - 7

Ok.

a= 2m
3m-2m
= a= m

Do note that i am a Sec 1 this year,
next year i'll be Sec 2! :yeah:

... :nope:
You know, I am in Sec 1 and you don't know basic equations
We weren't taught what M was.

- - - Updated - - -

What's M? As in X?

Sorry, i'm in Normal Technical.
I'm promoted to Normal Academic next year.
Sec 2NA

m is a non-zero number.
m = x?

X is a variable and can represent anything. Anything, zero or infinity.

I had an NA Maths Test yesterday.
Also, didn't know that. Ty. :)
But too much info. :)

1) Differentiate xlnx.

1ii) intergrate lnx with respect to x.

2) Given that in a equation x^2 -4x+ 8, the roots of the equation are alpha and beta. Find the quadratic equation for roots 3 alpha + beta.

3) A circle is given, such that it is touches the Y and X axis. If a line (9,8) is tangent to the curve at the circle, calculate the equation of the circle.

Solve these 3 and I'll call you my God.

Holy shite you guys are overthinking this, I just wanted a problem where the answer was a variable. I don't even know what half of you guys are talking about

2m - 3m x 5m + 12m - (3m+49m) = ?
