Hello.
First of all, let the number be t.
8 times t can be written like this:
Notice that the number is before the variable and the times sign (×) is not there.
We can write it as 8×t, but we usually write it as 8t.
The sum of means we add:
8t+21
Now, "less than" is "<" :
Therefore, the answer is
I hope it helps.
Have a nice day.
Answer: 1, 3, 5
let x represent the smallest consecutive odd integer
2x + 3 = x + 4
2x - x = 4 - 3
x = 1
therefore the lowest integer is 1, making the other two 3 and 5.

Answer:
$12000 at 5% for 8 years
Step-by-step explanation:
The amount in an account earning continuous interest is given by ...
A = Pe^(rt)
Then the interest earned is ...
I = P(e^(rt) -1)
For the two accounts, the interest earned is ...
I = 12000(e^(.05·8) -1) = 12000(0.491825) = 5901.90
I = 9000(e^(0.065·7) -1) = 9000(0.576173) = 5185.56
The $12000 account earns more interest, primarily because of the larger amount invested.
