Find two consecutive even integers such that the square of the second, decreased by twice the first is 52
Fiesta28 [93]

Let the first integer be x. So, the next even number is x+2

Let's translate the formula: the square of the second is (x+2)^2, twice the first is 2x. So, the equation is

(x+2)^2 - 2x = 52

Expand the square to get

x^2+4x+4-2x = 52 \iff x^2+2x+4 = 52 \iff x^2+2x - 48 = 0

The solutions to this equations are

x = -8,\quad x = 6

So, the possible consecutive even numbers are

-8\text{ and } -6\quad\text{or}\quad 6\text{ and } 8

Step2247 [10]

Answer: 3 people ordered soup.

Step-by-step explanation:

Let x be the number of people ordered salad and y  be the number of people ordered soup.

As per given,

x=2y           (i)

7.50x+6.25y= 63.75          (ii)

Substitute value of c =2y in (ii) , we get

7.50(2y)+6.25y= 63.75

⇒ 15y+6.25y =  63.75

⇒21.25y =  63.75

⇒ y= 3   [divide both sides by 21.25]

Then, x= 2(3) =6

So 6 people ordered salad and 3 people ordered soup.
