Marta’s fruit stand sold many oranges on Thursday and twice as many on Friday. All together, on both days, she sold 108. Which e

lianna [129]

Answer:

The equations that represent correctly the problem are A. 108 - 2x = x and D. x + 2x = 108

Step-by-step explanation:

Oranges sold on Thursday = x

Oranges sold on Friday = 2x

Oranges sold on Thursday and Friday = 108

Formula for calculating the value of x :

x + 2x = 108

The correct answer to this question could be alternative D. x + 2x = 108, but if we take a closer look, we'll find that there are other valid options.

A. 108 - 2x = x

- 2x - x = - 108 (changing the positions and putting the variables on one side and the whole number on the other)

x + 2x = 108 (multiplying by - 1 at both sides and it's also correct)

B. 2x - x = 108 (This is incorrect because the sales of Thursday plus the sales of Friday equal to 108, not minus)

C. x + 108 = 2x

x - 2x = - 108 (This is also incorrect because the sales of Thursday plus the sales of Friday equal to 108, not minus)

Now, let's find the solution

x + 2x = 108

3x = 108

X = 36 (Oranges sold on Thursday)

2x = 72 (Oranges sold on Friday)

After doing all this explanations, we found that equations A and D represent the problem.

If the endpoints of the diameter of a circle are (10, 12) and (0, 2), what is the standard form equation of the circle? A) (x +

attashe74 [19]

So the equation of a circle is (x - h)² + (y - k)² = r² where (h,k) are the coordinates of the center of the circle and r is the radius. The diameter of a circle is a line that goes from one point of the circle to the other through the center of the circle. Well the center would be midway through the diameter so use midpoint formula to find the center which is (h,k) Mid point formula is both given x's added together divided by 2 for h and both y coordinates added together divided by 2 to find k
(10+0)/2
10/2= 5
(12+2)/2
14/2 = 7
so the center of the circle is (5,7) now use distance formula using the center and one of the points to the radius
√((5-10)²+(7-12)²)
√(-5²+ -5²)
√(25 + 25)
√50 is the radius
Now plug all found information into circle equation
(x-5)² + (y-7)² =50 note the end is 50 because the circle equation is radius squared and since the radius is √50, radius² is 50.
