12) r=3, s=4, t=-2
First plug in the numbers to the equation rs-6+t
3(4)-6+(-2)
Then solve the equation using order of operations
12-6-2
Answer: 4
13) p=5, s=4, n=-6
Follow the same steps as question 12
10(5)/-6+4
50/-2
Answer: -25
8 = 8v - 4 (v + 8)
Distribute the 4 through the parentheses
8 = 8v - 4v - 32
combine like terms
8 = 4v - 32
add 32 to both sides
8 + 32 = 4v -32 + 32
combine like terms
40 = 4v
divide each side by 4
40/10 = v
4 = v
v= 4
I think it would be y=2(4x+200)
2 being it doubled and x would be to insert the twelve in to solve, and you add the 200 bacteria you already have.
8/9 - 5/9 = 3/9 = 1/3
Answer: 1/3 more must be filled
<u>Given</u>:
The given geometric series is
We need to determine the value of r and a₁
<u>Value of a₁:</u>
The term a₁ denotes the first term of the geometric series.
Hence, from the given series, the first term of the series is 2.
Thus, a₁ = 2.
Therefore, the value of a₁ is 2.
<u>Value of r:</u>
The term r denotes the common ratio between the terms in the geometric series.
The value of r is given by
Thus, the value of r is 1.5
