Answer:

Step-by-step explanation:

line that is parallel to x-axis  the slope = 0

an equation is : y= ax+b    a = 0

passes through the point (3,5) : y =5 when x = 3 so : b = 5

an equation is : y = 5

Half x + 10 equals quarter x + 54
IgorLugansk [536]
½(x+10) = ¼(x+54)
Solving it

x/2 + 5 = x/4 + 13.5
x/2 - x/4 = 13.5 - 5
x/4 = 8.5
x = 8.5 × 4 = 34

B. At the circus, three adult tickets and five child tickets cost $51, and five adult tickets
allsm [11]

Answer: x = $7, y = $6

Step-by-step explanation:

Let x be the cost of an adult ticket

Let y be the cost of a children's ticket

Translate these sentences to algebra:

At the circus, three adult tickets and five child tickets cost $51: 3x + 5y = 51

Five adult tickets and two child tickets cost $47: 5x + 2y = 47

Now we have two equations. Let's use substitution to solve.

3x + 5y = 51

3x = 51 - 5y

.: x = 17 - 5y/3

Now substitute this value of x into the second equation to find the numerical value of y:

5(17 - 5y/3) + 2y = 47

85 - 25y/3 + 2y = 47

-19y/3 = -38

-19y = -114

.: y = 6

Now find x:

x = 17 - 5y/3

x = 17 - 10

.: x = 7

So an adult ticket costs $7, and a child ticket costs $6 :)
