If you add all the hours with the denominator of 6 you get 9/6 hours, which ultimately is 1 and a half hours of work, D.
Let denote the -th term of the sequence, starting with the index . Denote by the forward differences of , that is
for . We have
which indicates is an arithmetic sequence with common difference between terms of 3 and starting with 4, so that
for . So we have
and so on, with the th term given by
Reversing the order of all but the first term in the sum gives
so that
for .
Answer to number 1: You would chose the even numbers because there are more even numbers and two odd numbers equals an even number. There is a less chance to get an odd number.
Answer for number 4: You would need a total of 1,369 cubes. To get the answer multiply 37*37 because the number of steps are squared to equal the number of cubes. If you have the number of cubes then you would find the square root to get the steps. Ex: 9 cubes would equal to 3 steps, 16 cubes equals 4 steps. If you have 16 steps you have 256 cubes.
Answer:
x= -14
Step-by-step explanation:
-x+8+3x=x-6
The first step is to simplify both sides
8+2x=x-6
Now you want to put all the xs on one side and the other like terms on the other side (Subtract both sides by x and subtract both sides by 8 so the x is alone on one side)
x= -14
Answer:
11 3/4 miles.
Step-by-step explanation:
Converting to improper fractions, the consecutive distances are:
21/4 , 55/8, 17/2
= 42/8, 55/8, 68/8 for Monday, Tuesday and Wednesday.
So the distances have increased by 13/8 miles each day.
Thus number of miles he'll bike on Friday = 68/8 + 2(13/8)
= 94/8
= 11 3/4 miles.
