Answer:

x = -7

Step-by-step explanation:

1. Write the equation.

-12 = x - 5

2. Since 5 is negative and we want to leave <em>x</em> by itself, add 5 to both sides. Adding 5 with cancel out the -5.

-12 +5 = x -5 +5

3. When you add +5 to -12, the equation you are left with will be:

-7 = x

Hope this helps :)

Suppose that you spin the double wheel pictured to the right. Assuming that the wheels are independent and each outcome is equal
Anna11 [10]

Answer:

0.125

Step-by-step explanation:

<u>Smaller Wheel</u>

Total Number of Equal Sectors = 8

The number of Red sectors =3

The probability of obtaining red on the smaller wheel =\dfrac38

<u>Larger Wheel</u>

Total Number of Equal Sectors = 12

The number of Red sectors =4

The probability of obtaining red on the larger wheel =\dfrac{4}{12}

Assuming that the wheels are independent and each outcome is equally​ likely, the probability that we get red on both wheels

=\dfrac38 \times \dfrac{4}{12}\\\\=\dfrac18\\\\=0.125

The probability is: 0.125

There are 33 of them altogether and pay £311 in total. How many kids are in the family? Adults pay £15 and kids pay £7
Marrrta [24]

Answer:

Step-by-step explanation

  1. Let x be the number of adults and y the number of kids

We can then write this two equations :

          x+y= 33

          15x+7y= 311

  • let's solve the two eaquations

to do that we should combine them both in a way that help us get rid of one of the variables.

             Let's multiply the first equation by -7 to get rid of y by adding it to thr second equation

             -7x-7y= -231

        now add both equations .

              15x+7y-7x-7y=311-231

    we get :  8x = 80

as you notice y is gone and we get a classic easy equation to solve

                x= 80/8

                   = 10

so the number of adults is 10

let's go back to the first equation ( x+y= 33) and replace x with 10

                10+y= 33

                  y= 33-10

                     =23

let's check using the second equation :

            (10*15)+(23*7) = 311

that is true

so :

  •  the number of adults is 10
  • the number of kids is 23
