If Marcus can type 40 words in half a minute, then 40 times 2 equals 80. 80 words a minute for Marcus. If Rhys can type 100 words in 1 1/2 minute, 100/ 1.5 = 66.66 and 80>66.66 so Marcus can type a greater rate of words per minute.
Answer:
The answer is 50
Step-by-step explanation:
40-10=30
30+20=50
Answer: 5x^2 - 5x - 6
work:
5x^2 -3(x+2) - 2x
distribute
5x^2 -3x - 6 - 2x
combine like terms
5x^2 -5x - 6
Answer: x= 8
Step-by-step explanation:
According to the converse of basic proportionality theorem,
If in ΔABC , DE is a line drawn from AB to AC such that 
then, DE is parallel to the third side BC.
Applying converse of basic proportionality theorem, to get NO parallel to KJ, we must have

Hence, the value of x should be 8, so that Line segment N O is parallel to line segment K J.
