They are counting by twos.
2,4,6,8,10,12,14,16,18,20,etc
Answer:
9a = 11a - 2a
9a = 9a
Step-by-step explanation:
9a = 11a - 2a
11 - 2 = 9
Similarly, 11a - 2a = 9a
Eleven minus two equals nine. Similarly, 11a minus 2a equals 9a. You can subtract them because they both have the same variable <u><em>a</em></u>.
Answer:
a=31.61
Step-by-step explanation:
Pythagorean theorem states that square hypotenuse side is equal to square opposite side plus square adjacent side
Hyp²= Opp²+Adj²
the opposite is represented by a in the question, so
60²=a²+51²
3600=a²+2601
combine the like terms
3600-2601=a²
999=a²
a²=999
square root both sides to remove the square
√a²=√999 {square cancels the square root
a=√999
a=31.606
a=31.61 approximately
I have no idea what to do. We have to do the same stuff too
