Simon has more money than Kande. if Simon gave Kande K20, they would have the same amount. While if Kande gave Simon $22, Simon

Given parameters;

  Let us solve this problem step by step;

Let us represent Simon's money by S

Kande's money by K

  • Simon has more money than Kande

               S > K

  •  if Simon gave Kande K20, they would have the same amount;

 if Simon gives $20, his money will be  S - 20 lesser;

      When Kande receives $20, his money will increase to K + 20

                     S - 20  = K + 20   ------ (i)

  • While if Kande gave Simon $22, Simon would then have twice as much as Kande;

          if Kande gave Simon $22, his money will be K - 22

    Simon's money, S + 22;

                  S + 22  = 2(K - 22)    ------ (ii)

Now we have set up two equations, let us solve;

         S - 20  = K + 20  ---- i

         S + 22  = 2(K - 22)  ;       S + 22  = 2K - 44  ---- ii

So,      S - 20  = K + 20

          S + 22  = 2K - 44

subtract both equations;

               -20 - 22  = (k -2k)  + 64

                   -42  = -k + 64

                       k  = 106

Using equation i, let us find S;

            S - 20 = K + 20

             S - 20  = 106 + 20

              S = 106 + 20 + 20  = 146

Therefore, Kande has $106 and Simon has $146

Solve for x. Show each step of the solution. 5.5(8-x)+44=104-3.5(3x+24)
earnstyle [38]
5.5 ( 8 - x ) + 44 = 104 - 3.5 ( 3x + 24 )

Distribute 5.5 through the parenthesis.

44 - 5.5x + 44 = 104 - 10.5x - 84

Add the numbers.

88 - 5.5x = 20 - 10.5x

Move variable to the left side and change its sign.

88 - 5.5x + 10.5x = 20
-5.5x + 10.5x = 20 -88

Collect like terms.

5x = 20 - 88

Calculate the sum or difference. 

5x = - 68

Divide both sides by 5.

x = - 68 / 5

katelyn has taken 4 math quizzes. Her scores were 75,80,97, and 92. What must she get on her next quiz to have an average of at
Vilka [71]
To find the average add all the numbers together then divide by how many numbers there are.

75+80+97+92=344 divided by 4 = 86

So her average right now is 86.

She’d have to make 96 to get an average of 88.

75+80+97+92+96=440 divided by 5=88

The answer is 96

Solve for xx. Round to the nearest tenth of a degree, if necessary.
Tanya [424]

Answer:

56.6 °

Step-by-step explanation:

For a RIGHT triangle    cos (x ) = adjacent leg / hypotenuse

                                      cos (x) = 4.4 / 8

                                            arc  cos (4.4/8) = 56.63 °  = ~ 56.6°
