It's 5.
1/2 can also be written as 4/8.
So, it's 3 and 4/8 plus 1 and 4/8.
Answer:
B and D
Step-by-step explanation:
Geometric sequences and series. A geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio, r.
an = ar^(n-1)
d) 1/3, 2/3, 4/3, 8/3, 16/3, . . . .
1/3 * 2 = 2/3
2/3 * 2 = 4/3
4/3 * 2 = 8/3
where r = 2, constant multiplier is 2. //Answer
b) 320, 80, 20, 5, 1.25, . . . . .
320 * 1/4 = 80
80 * 1/4 = 20
20 * 1/4 = 5
r = 1/4 //Answer
Answer: B and D
//Hope this helps.
Answer:
Subtract 21 from the left side and add 21 to the right side of the equation.
The answer is b = 198.
Check the solution by substituting 198 for b.

Answer:
5 and 12
Step-by-step explanation:
First, set up an equation. Since it says that one number is 7 less than the other, we can use x for the number that is 7 less than the other number, and x+7 to represent the other number. We set the equation equal to 17 because the question says that the sum of two numbers is 17.
x+x+7=17
Then, you solve the equation:
x+x+7=17
2x+7=17
2x=10
x=5.
So, the number that is 7 less than the other number is 5. To find the other number, we would add 7 to 5 because the other number would be 7 more than 5.
7+5=12
The two numbers are 5 and 12.
