20 that is one of the most stupid questions I have ever heard unless you are in 1st grade

Do you have an example

F = G M m / r^2      Did you use r = radius of the earth?  And G=gravitational constant = 6.67 x 10^(-11)

Take 7 minus 4, that is 3. So 3n has to bee equal to 3 and therefore n=1 because 1x3 = 3.

Well, it basically tells you that   3/4 - 1/8 = 42 Gallons

6/8 - 1/8 = 42 gallons

5/8 tank = 42 gallons     multiply both sides by 8/5

1 tank = 42 (8/5) gallons  = 67.2  gallons  

Nvm ill use paper

3n+4=7

1.take four from both sides

2.then divide both sides by three.

1. 3n=3

2. n=1

so n equals one

Ask melody

4 + 12/a + 36/a^2 + 108/a^3 + 324/a^4.................If a=4, then by convergence test we get:

[4+∑(4*3^n)/4^n)), n=1 to ∞] =16, so a=4 is correct. The infinite series: 4/(1 - r)=16, r=3/4.

3n+4=7 |-4

    3n=3  |:3

      n=1

I believe that this would be 100

(5 × 4) × (16 ÷ 8) × (24 − 22) = 20 x 2 x 2 = 40 x 2 = 80

4 ok

It's 4

Ye

I agr ee with jocob msg me if u wanna talk

You'd start by distributing the coeffecient of the term 3(p-2), giving you 3p-6+2p overall. You'd combine like terms, giving you 5p-6, simplifying the problem.

54.5=54 1/2 or 109/2

Add 'x'    and   SUBTRACT '84 from both sides to get

36 = 6x      divide both sides by '6'

6 = x

Add 'x'   AND  SUBTRACT '84' from both sides to get

36 = 6x    divide both sides by '6'

6 = x

2300 IS in decimal form      2300.

4 + 5x = x+2    Subtract 'x' from both sides

4 + 4x = 2         Subtract '4' from both sides

4x = -2             Divide both sides by '4'

x = -2/4            Simplify

x = - 1/2            Ta-Da !

I answered on the original question.

and yes EP is correct :))
