II. Multiply mentally the fractions given. Then write TRUE on the blank before each number if the statement is true, and if False write the correct number to make it true 16. 1/3 x4 = 1/12 17. 2/5 x = 1/5 18. 1/7 *2/3 = 2/21 19. 215 x 1/3 = 2/15 20. 1/5 x 1/3 = 1/15 21. 2/5x 1/8 = 2/3

i believe the answer is the polygon, heptagon.

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

true
