Answer:
Option A) Bethany is correct because consecutive odd integers will each have a difference of two
Step-by-step explanation:
The sum of 3 consecutive odd integers is 91. Let the first odd integer is x. The next odd integer will be obtained by adding 2 in x i.e. (x + 2). The third odd integer will be obtained by adding 2 in the second odd integer i.e. (x + 2) + 2 = x + 4
So, the 3 odd integers will be:
x , (x+2) and (x+4)
Their sum is given to be 91. So we can write:
x + (x+2) + (x+4) = 91
Hence, we can conclude that: Bethany is correct because consecutive odd integers will each have a difference of two.
Other options are not correct because consecutive odd integers always increase by 2. For example, the next odd integer after 1 is 3, which is obtained by adding two, similarly the next odd will be 5 and so on.
Answer: x= 3.8
Step-by-step explanation:
21.1 - 8.3 = 3.8
x= 3.8
Below, H = heads, T = tails, and 1, 2, 3 are the number outcomes of the spinner. For example, H1 means heads on the coin toss followed by 1 on the spinner.
If heads appears, a spinner that can land on any number from 1 to 3 is spun.
This gives possible outcomes: H1, H2, H3
If tails appears, a second coin is tossed
This gives possible outcomes: TH, TT
All outcomes are: H1, H2, H3, TH, TT
