How do i solve this? and what’s the answer?

x = 18

Step-by-step explanation:

The line joining 2 midpoints of the non parallel sides of a trapezoid is 1/2 the sum of the two parallel lines.

Put in much simpler language XY = 1/2 (BC + AD)

4x - 2 = 1/2 (6x + 1 + x)                         Combine the right

4x - 2 = 1/2 (7x + 1)                               Multiply by 2

8x - 4 = 7x + 1                                       Add 4 to both sides

8x = 7x + 5                                           Subtract 7x

x = 5

But what you want is the length of XY

XY = 4x - 2 = 4*5 - 2 = 18

Sorry I noticed too late that I used x for s. The answer would still be 18.

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
