What multiplies to be 1/4 but adds to be 1

Let x be that number.
Let's create a system using what we have:
x^2 = 1/4 (1)
x+x = 1 (2)

In the equation (1):
x^2 = 1/4
So x = √1/4 = 1/2 OR x = -√1/4 = -1/2
Since the answer in the second equation is positive, so the acceptable answer is x = 1/2.
So the number that multiplies to be 1/4 but adds to be 1 is 1/2.

You can re-check your answer (very important):
x^2 = (1/2)^2 = 1/4
x+x = 1/2 + 1/2 = 1
The answer has been approved.

Hope this Helps! :)

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 :)
