240 is the answer to your question just multiply them
Answer:
A, B, D
Step-by-step explanation:
2 x 3x =6x - 2 times 9y which equals 18y+ and 2 times 18 equals 36 so 2(3x-9y+18)
You need to order the data, so
11, 12, 13, 14, 14, 15, 17, 17, 18, 18, 18, 20
Then find the middle of the data. Because there are 12 data points, the median will lie between the two 6th placed numbers
The two numbers are 15 and 17, so work out the mean of them. (15+17)/2 = 16
So the answer is B. 16
Answer: 3/6
Step-by-step explanation:
Anytime you want to figure out the ratio, you divide the denominator (bottom number) by the numerator (top number).
First divide 14 by 7 and you get 1/2 (or 0.5 if you used the calculator). Now do this for each of the others until one matches or has the same ratio.
a) 5/12 : 12 ÷ 5= 2.4 * Not a match
b) 2/5: 5 ÷ 2= 2.5 * Not a match
c) 4/9: 9 ÷ 4= 2.25 * Not a match
d) 3/6: 6 ÷ 3 = 0.5 This is a MATCH!!!
