The number of kids in your group is 12.
Step-by-step explanation:
Given,
Number of people = 20
Cost of each kid ticket = $4
Cost of each adult ticket = $6
Total spent = $96
Let,
x be the number of kids ticket
y be the number of adult ticket
According to given statement;
x+y=20 Eqn 1
4x+6y=96 Eqn 2
Multiplying Eqn 1 by 4

Subtracting Eqn 3 from Eqn 2

Dividing both sides by 2

Putting y=8 in Eqn 1

The number of kids in your group is 12.

Answer:
(-1,-2) OR x = -1 and y = -2
Step-by-step explanation:
y = 3x + 1
y = -x -3
so you would first multiply everything on y = -x -3 by 3 and get 3y = -3x -9
so then you would add 3y = -3x -9 to y = 3x + 1 (<u> to eliminate the x</u> )which would be 4y = -8 then divide by 4 and get <u><em>y = -2</em></u>
then you plug in y = -2 into any one of the equations but to make it easier i am going to plug it into y = -x -3 so now it would be -2 = -x - 3 then, add 2 to both sides which would be 0 = -x -1 then add 1 to both side 1 = -x then multiply both sides by -1 and get <u><em>x = -1</em></u>
<u><em>SO your answer would be </em></u> (-1,-2) OR x = -1 and y = -2 ( both of them are correct but it depends on what the teacher taught you)
This problem is solved better well when given the drawing
or the figure. It may have been given and you forgot to attach it in the
question. However, so that we can solve this now, I drew the figure on my own
(see the attached pic).
We can see from the figure that two parallel lines are
intersected by a straight line. This type of scenario creates special angles.
Angle PXY and angle RYX are called alternate interior angles since they are on
the interior opposite sides of the cut.
By virtue of alternating interior angles, angle PXY and
angle RYX are congruent hence:
m∠RYX = m∠PXY
m∠RYX = 64.36°
