Answer:
4/15
Step-by-step explanation:
to find out the portion that is shaded we can do the following:
1 - (1/3 + 2/5)
now we want a common denominator, we can use 15:
15/15 - (5/15 + 6/15) → 15/15 - 11/15
the answer is 4/15
Answer:
the first one
8x+5
Step-by-step explanation:
10x-2-2x+7= 8x+5
Answer:
1 l 0 0 5 5 5
2 l
3 l 7
4 l
5 l
6 l 5
7 l 0
8 l 68
9 l
Step-by-step explanation:
1 l 0 0 5 5 5 =10,10,15,15,15
And so on.
1. Correct answer is a (since when you are not given the n values, it is implied that the first value is 1).
3. Correct answer is a (a(n)=-3+4(1-1)=-3).
7. The pattern is to reduce the previous value by 4, thus the 12th term of the sequence is -24 (a(n)=20 - 4(n-1)=20 - 4(12-1)=-24).
8. Missing term is 26 (32+20=52; 52/2=26).
10. Pattern is 625/1=625; 625/5=125; 125/5=25; 25/5=5, thus. the 10th term is 1/3125 (answer a).
