Thx so much 

common difference , d = -3

a1 + 82 d  = 83rd term

-23 + 82(-3) = ______________

50 describes it best           y = amount of money he has    x = time in months          y = 50 + 30x 

p = origina amount

p - 1/2 p  -  1/4 p  - 1/6 p  = 3

(12-6-3-2)/12 p = 3

1/12 p = 3

p = 36 pearls

0.3÷2 = 0.15
1S : 1B = 2x  : 3u+0.15

2S+5B = 4x+15x+5×0.15 = 8.35
x  = (8.35-5×0.15)÷(4+15) = 0.4

All big →
5 × (3u+0.15)
= 5 × ( 3×0.4 + 0.15 )
= 6.75 kg (Ans)

Put everything except the constants on one side

x^2 -28x     + y^2 +2y = 28    complete the squares for x and y

(x-14)^2      + (y+1)^2   = 28 + 196 + 1 =225

center is   14,-1       radius is sqrt225 = 15   <=========you can finish

Your answer is correct!!!        1/3(1/4) = 1/12

I should have divided 1/12 by 1/4               (1/12) / 1/4 = 1/3

8 or -8

1 + 3 = 4

48 * 4 = 192

Additonal money paid by Paul = 192 + (48*2)

                                                 = $288

12/70 = 6 : 35

x = price

Jack paid    48 + 2/11x

  Paul paid 3 times as much

48 + 2/11 x   +  3 (48 + 2/11 x)  = x

192 = 3/11 x

x = 704

So jack paid   176     <====== you can finish ~!

Jack and Paul shared the total cost of a present for their father. Jack paid $48 more than 2/11 of the cost of the present. The ratio of the amount paid by Jack to the amount paid by Paul was 1:3. How much more did Paul pay for the present than Jack?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Jack's share = (2x/11) + 48

Paul's share = (9x/11) - 48

[(2x/11) + 48] / [(9x/11) - 48] = 1/3

x = 704

[(9x/11) - 48] - [(2x/11) +48] = 176

Paul paid $352 more than Jack.

Cost of fish burger is 3 times cost of chicken wing

She spent 1/4 of her money on 6 wings

                                           and 2  f.b.

                                          Total = 12

           1/4 of her money = 12

           4/4 of her money = 48

    Remainder of her money = 48 - 12

                                             = 36

    She spent 2/3 of remainder on fish burger.

               2/3 of remainder = 2/3 * 36

                                          = 24

  She spent 24 on rush burgers.

   Since f.b. Costs 6 each,

             24 ÷ 6 = 4 fish burgers

From the first    a = 384/b⁴     sub this into the second equation for a    then solve for b   and subsequently 'a'

fish burger => fb            chicken wing => cw

2 fb = 6 cw             2 fb + 6 cw = $1/4             2 fb = 1/8

Remaining money = 3/4

3/4(2/3) = 1/2

So, she bought 8 more fish burgers with 2/3 of her remaining money.

Total = 12x

Ted = 9x

White = 3x

Total used = 6x (1/2 of total)

Red used = 5x,

Therefore, white used = 1x

Fraction of white

= used white / Total white

= 1/3

C : 7

4 : 7

=> 60 : 105 ( multiply by LCM of 3,5)

Given away : 1/5 * 60 = 12 of chairs

                      2/3 * 105 = 70 of tables

Therefore  :   Ratio is = 12 : 70

                                   = 6 : 35

c/t = 4/7   

gave away 1/5c    and 2/3 t

1/5 ( 4) / ((2/3)(7)

4/5  /  14/3

12 / 70   = 6:35      is  C:T       T:C = 35:6

5/12 - 1/12 = 4/12 = 1/3

1/3 of the fraction of the white beads

It's not homework, its just a question i need help.

It's not a test

Are you like trying to do a test and you have a time limit?

Here ya go....I did the first line....see if you can follow the example to do the rest
