It depends upon how many tests that you have already taken.

If you have taken only one, then one way to solve the problem is this:  (71 + 3x)/4  =  77

--->     71 + 3x  =  308   

--->             3x  =  237

--->               x  =  79

You would have to average 79 on the last three tests.

sqrt3(216) = 6

1)  x^2 + 10x + 3 = 0

The sum of the roots is given by  2 (-b)/(2a)  = -b/a   =  -10/1  = -10

2)

500,000 = P (1 + .08/12)^(34*12)    where P is what we're looking for.......simplify...

500,000 = P(1 + .08/12)^408    divide both sides  by (1 + .08/12)^408

500,000/ (1+ .08/12)^408  = P  = about  $33,236.03

y = 2x - 8

y = (1/3)x - 1

Set the y's equal, and we have

2x - 8   = (1/3)x - 1      subtract (1/3)x from both sides....add 8 to both sides

(5/3)x = 7       multiply both sides by (3/5)

x = (3/5) * 7   =  21 / 5   = 4 + 1/5

circumference divided by diameter. 22/7 is a very close estimate.

Find the diameter of the sphere. Then use the formula

V=4/3πr3

(volume equals four thirds pi radius cubed)

3x^2 - x^2 = 10   simplify

2x^2  = 10     divide both sides by 2

x^2  = 5       take rhe square root of both sides

x  = ±√5

If this is supposed to be

2.3^2 + 2.5^2   we have

11.54   = 11 + 54/100   = [ 11 + 27/50 ]   miles

If it's supposed to be

(2/3)^2  + (2/5)^2  =

(4/9) + (4/25)   =    [common denominator = 225]

[ 100/225] + [ 36/225]  =

[136 / 225 ]miles

3 girls can sit together in groups of 3 in chairs 1 - 7.....and they can be arranged in 3! ways for each of these seatings

And for each of these seatings, the boys can be seated in 5! ways 

And 4 girls can sit together in groups of 4 in chairs 1 - 6.....and they can be arranged in 4! ways for each of these seatings

And for each of these seatings, the boys can be seated in 5! ways 

So...the total arrangements = 

7 * 3! * 5!   +  6 * 4! * 5!   = 22,320   arrangements

Both of the repliers are correct, yet wrong. 0/0 does not yield a result, 0/0 is an undefined number.

Classic division such as a/b = c shows that a = b*c. We could solve for 0/0 in this manner, if a = 0 and b = 0 then 0 = 0*c and this holds true for any number which includes c = 0 and i. However, any number divided by 0 is not equal to zero, in fact any number divided by zero is actually undefined such as above.

25 * 3/5 = 75/5 = 15 students

 zero. Anything multiplied or divided by zero is zero.

Hello Alan. Thank you!

Sorry for my mistake!

sin150° = sin ( 30°)

Greeting asinus :- )

 !

0/0=i

i is an imaginary number, such as the square root of -1.

i think you can t simplify it any more you can only multiply both by y you wil get (x-y)/(a+by) :/
 

As follows:

\(\frac{u^3-3u^2+2u}{u^2-1}\rightarrow \frac{u(u-1)(u-2))}{(u+1)(u-1)}\rightarrow \frac{u(u-2)}{u+1}\)

.

2 divided by 1/4 is 2 times 4/1 equal 8

so the final answer is 8

It is 8 

The series is given by :

a_n = 9^{n -1}  =  (1/9)*9ⁿ    where n is the n^th term

So

a₈ =  (1/9)*9⁸ = 4,782,969

pi is important because it helps us to solve math equations, like the area, volume, and circumference of a circle.

You might have to rephrase your question.

Good job, rarinstraw.
