so

step 1
Find the length side B.C

substitute the given values

step 2
Find the length side C.D
Remember that

therefore

step 3
Find the length side E.D
we know that

substitute the given values

step 4
Find the length side E.F
Remember that

therefore

step 5

Answer:
Hi. 9/14 is a fraction already. Maybe you meant decimal?
Step-by-step explanation:
Answer:
6 times a larger number (so 6y) is equal (=) to the sum of a smaller number and 18 (x+18)
6y = x+18
Twice of larger number (2y) and the difference of smaller number (x) is equal to 6
2y - x = 6
solve for y. Divide both terms for 6.
6y/6 = 1/6x+3
y = 1/6x+3
second equation solve for y
move x to the right of equal
2y = x + 6
y = 1/2x + 3
Answer: 1.18
Step-by-step explanation:
Z = (x - mean) / standard deviation
Z = (85 - 71.4) / 11.5
Z = 13.6 / 11.5 = 1.18
