1/1+2/4

\(\frac {1}{1}+ \frac {2}{4} = \frac{4+2}{4}= \frac {6}{4}= \frac {3}{2}{\color{blue}\ =1 \frac {1}{2}}\)  !

-1.75(q-5)>3(q+2.5)

-1.75q + 8.75 > 3q + 7.5

3q + 1.75q < 8.75 - 7.5

4.75q < 1.25 multiply both sides by 100

475q < 125 divide both sides by 475

q < 5/19

the ratio of club soda to cranberry juice in a drink is 3 : 7 If 15 L of club soda are used in the mixture, how much cranberry juice is neededÉ

Solve for x:
(7 x)/3+1/5 = (5 (x+2/5))/(3)

Put each term in x+2/5 over the common denominator 5: x+2/5 = (5 x)/5+2/5:
(7 x)/3+1/5 = 5/3 (5 x)/5+2/5

(5 x)/5+2/5 = (5 x+2)/5:
(7 x)/3+1/5 = 5/3 (5 x+2)/5

(5 (5 x+2))/(5×3) = 5/5×(5 x+2)/3 = (5 x+2)/3:
(7 x)/3+1/5 = (5 x+2)/3

Put each term in (7 x)/3+1/5 over the common denominator 15: (7 x)/3+1/5 = (35 x)/15+3/15:
(35 x)/15+3/15 = (5 x+2)/3

(35 x)/15+3/15 = (35 x+3)/15:
(35 x+3)/15 = (5 x+2)/3

Multiply both sides by 15:
(15 (35 x+3))/15 = (15 (5 x+2))/3

(15 (35 x+3))/15 = 15/15×(35 x+3) = 35 x+3:
35 x+3 = (15 (5 x+2))/3

15/3 = (3×5)/3 = 5:
35 x+3 = 5 (5 x+2)

Expand out terms of the right hand side:
35 x+3 = 25 x+10

Subtract 25 x from both sides:
(35 x-25 x)+3 = (25 x-25 x)+10

35 x-25 x = 10 x:
10 x+3 = (25 x-25 x)+10

25 x-25 x = 0:
10 x+3 = 10

Subtract 3 from both sides:
10 x+(3-3) = 10-3

3-3 = 0:
10 x = 10-3

10-3 = 7:
10 x = 7

Divide both sides of 10 x = 7 by 10:
(10 x)/10 = 7/10

10/10 = 1:
Answer: |x = 7/10

It is called "Googolplex"!. Do you understand what a trillion is? It is 1 followed by 12 zeros. Will call it a "T" for trillion. A Googolplex is 1 followed by: T x T x T x T x T x T x T x T x 10,000 zeros!!!!!!!!!!

Do you think you can comprehend that?.

i dont know but you can go to khan academy to find out.

copy and paste it into the calculator here!.

Always give an example!.

use the ' / ' symbol for division

18

use -16^(1.5/2) instead and it will give you the answer

my equation is Nx=No(1+R)^x and No=150 R=14 and x is 30. whats N?

30N =150 [1.14]^30, solve for N

Solve for N:
30 N = 7642.52

Divide both sides of 30 N = 7642.52 by 30:
(30 N)/30 = 7642.52/30

30/30 = 1:
N = 7642.52/30

7642.52/30 = 254.751:
Answer: |N = 254.751

See the answer under your first post.

0,6,24,60,120,210? Yes!. There is a pattern, which is: n^3 - n. So, your next terms will be:

336, 504, 720.....etc.

0, 4, 10, 20, 35, 56, 84, 120, 165, 220, 286, 364, 455, 560, 680, 816, 969.......etc.

There is a pattern generated by this rather complex formula:

G_n(a_n)(z) = (z (-z^3+4 z^2-6 z+4))/(z-1)^4

There may be simpler generating formulas, but can't see it!.
