NEED HELP WILL MARK BRAINLIEST
Alan solved the proportion x over 200 = 8 over 25 as shown.

x over 200 = 8 over 25 . (8) (x) = (25) (200). 8 x = 5,000. 8 x over 8 = 5,000 over 8 X = 625.

What is Alan’s error?

Step 2 was his error.

The following problem is solved by Alan:

In solving for x, you have to cross multiply between the numbers.

In that case, step 2 would look like this:

(25)(x) = (8)(200)

NOT THIS:

(8)(x) = (25)(200)

Now continue all the way.

25x = 1600

x = 1600 ÷ 25

x = 64

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
