How do you solve this?​
GrogVix [38]

Answer:

Step-by-step explanation:

set it up like this

19x + 11 = 11x + 4

then self like algebra

19x + 11 -4 = 11x + 4 - 4

19x + 7 = 11x

19x -11x + 7= 11x -11x

8x ÷ 8 + 7 ÷ 8

x = 0.875

plug it into

19x + 11

19 × 0.875 + 11 = 27.625

so 27.625  should be your answer

Some boys and girls are waiting for school buses. 25 girls get on the first bus. The ratio of boys to girls at the stop is now 3
Molodets [167]

Answer:

100

Step-by-step explanation:

Forming algebraic equations and solving:

Let the number of boys originally  at the stop = 'x'

Let the number of girls originally at the stop = 'y'

25  girls get on the first bus.

⇒ The number of girls now at the stop = y -25

Ratio of boys to girls:

        \sf  \dfrac{x}{y -25}= \dfrac{3}{2}\\\\Cross \ multiply,\\\\2x = 3*(y- 25)\\\\2x = 3y - 3*25\\\\2x = 3y - 75 ------(I)

15 boys get on the second bus.

Now, the number of boys at the stop = x - 15

Number of girls at the stop = y - 25

Ratio of boys to girls,

     \sf \dfrac{x - 15}{y -25} = \dfrac{1}{1}\\\\Cross \ multiply, \\\\x - 15 = y -25\\\\

             x = y -25 + 15

             x = y - 10

Plugin x = y - 10 in equation (I)

          2*(y-10) = 3y -75

          2y - 20  = 3y -75

                -20 = 3y - 75 - 2y

                -20 = y -75

         -20 +75 = y

                 \sf \boxed{\bf y = 55}

Plugin y = 55 in equation (I)

       x = 55 -10

        \sf \boxed{\bf x = 45}

Number of students originally at the stop = x + y

                                                                     = 55 + 45

                                                                     = 100
