If something decreases by35%, it must be only 65%  (.65) of what it was....

So....

.65 x 90  =  ???

i think the answer is 330,300,000,000,000,000,000,000 

$${\mathtt{9}}{\mathtt{\,\small\textbf+\,}}{\mathtt{10}} = {\mathtt{19}}$$

$${\mathtt{9}}{\mathtt{\,\small\textbf+\,}}{\mathtt{10}} = {\mathtt{19}}$$

I have drawn exactly what you have described......well, at least some of it....

Notice that AE and BD don't interesect, at all...!!! And the two triangles formed aren't congruent - or similar - either.......are you sure you have the correct info, here???

x² + 2x - 24  =  -24

Add 24 to both sides:   x² + 2x  =  0

Factor:                       x(x + 2)  =  0

Set each factor equal to zero:     x  =  0         or        x + 2  =  0   --->   x  =  -2

The shortest distance from where to where?

The shortest distance from home plate to second base:

--- From home plate to first base to second base and back to home plate forms a right triangle with the right          angle at first base. The distance from home to second is the hypotenuse, so use the Pythagorean Theorem:

     c²  =  a² + b²   --->  c²  =  90² + 90²   --->   c²  =  8100 + 8100   --->   c  =  √16200

          --->   c  ≈  127.3.   

y = 43.81 - .395x    let y = 15....so we have

15 = 43.81 - .395x   subtract 43.81 from both sides

-58.81 = -.395x       divide both sides by -.395

x = about 149 mph  !!!!

I'll give h7 40% of the credit and Alexa 60% of the credit......

That seems fair.....!!!

See???..I arbitrarily gave you 3 points for that reply.....

Most of those words made no sense to me......so THANK YOU FOR OFFICIALLY WASTING MY TIME!!!!

Hello anon user!

To make a rectangle,  there would need to be 2 pairs of the same coordinate on the x-axis and 2 pairs of the same coordinate on the y-axis.  (if that makes sense)

The coordinates for the x-axis:7,-4  There need to be two of each of these

The coordinates for the y-axis:2,4   There need to be two of each of these

From the first three points,  there were two 7's (for the x-axis) and two 2's (for the y-axis)

To make a coordinate,  you go from the x-axis location to y-axis location

Missing x-axis location:-4

Missing y-axis location:4

So the missing coordinate would be (-4,4),  to make a rectangle of (7,2), (7,4), (-4,2) and (-4,4)

I hope I helped you anon!

Hey h7, we mods don't deal in "fair".....we only deal in "abitrary" and "capricious".........

Remember.....WE HAVE THE POWER  !!!!!

Division is simpled than you'd know.

When you say "23 divided by 32"  that is the same as saying "23 over 32"

If you want fractions,  that's all you need.  If you want whole numbers and decimals,  there is a little more you need to do

Good job Alexa

Ahhhhhh I think im going to be sick Wheres that troll when we need him

CPHILL!  HOW IS THAT FAIR?

Alexa gave the anon person a hint on how to solve it

Rosala solved it completely

I would give them 50-50 or give Alexa more credit!  This is most likely someone's schoolwork,  and would a teacher give them the entire answer because they asked?  Heck no!  A teacher would hint them on how to solve it,  so I take Alexa's answer........(no offense,  Rosala)

Notice that...

0 x 0 = 0   and

1 x 1 = 1

So, we might assume that multiplying any number by itself just returns that number to us...

But if 2 x 2 = 2   divide both side by 2...so we have

2 = 2/2

2 =1   Mmmm...that can't be true...!!!

OK, rosala...I'll give you 60% of the credit and Alexa 40% of the credit....LOL!!!

3x-6y=6

6x-12y=15

This equation has no solution.....to see why....multiply the first equation by 2 on both sides...this gives 6x - 12y = 12

But the second equation says that the same quantity on the left hand side = 15. And one thing cannot equal two different things at the same time !!!

-----------------------------------------------------------------------------------------------------------------

2x-5y=-33

5x+2y=19

Let's multiply the top equation by 2 and the bottom equation by 5....this will eliminate y.......so we have

4x  -  10y = -66

25x + 10y = 95      add the equations

29x  = 29              divide both sides by 29

x = 1                   and using the first equation to find y, we have

2(1) - 5y = - 33 

2 - 5y = -33

-5y = -35           divide both sides by -5

y= 7

So...our solution is (1, 7)

Thanks CPhill and Alexa,btw even I do it mostly! Lol!😉😃

Let's see

4 x .13  = .52lbs

4 x .6 = 2.4lbs

4 x .12= .48lbs

Yep....it looks like everything is OK....!!
