First, let's write an equation for the situation.
Jim's weight is 30 pounds less than Tom's, so his weight is:
n - 30
If Tom's and Jim's weights add to 210:
n + (n - 30) = 210
Solve for n:
2n - 30 = 210
2n = 240
n = 120
Tom weighs 120 pounds.
Decimals that are equivalent to fractions with denominators of 100
The answer is letter C, which is (2,1)
7/12 divided by 2/5 is 35/24
Answer:
Step-by-step explanation:
A geometric sequence is a sequence in which the successive terms increase or decrease by a common ratio. The formula for the nth term of a geometric sequence is expressed as follows
Tn = ar^(n - 1)
Where
Tn represents the value of the nth term of the sequence
a represents the first term of the sequence.
n represents the number of terms.
From the information given,
r = 1/3
T3 = - 81
n = 3
Therefore,
- 81 = a× 1/3^(3 - 1)
-81 = a × (1/3)^2
-81 = a/9
a = -81 × 9 = - 729
The exponential equation for this sequence is written as
Tn = - 729 * (1/3)^(n-1)
