Distribute the .25 to get .25x + 1 - 3 = 28
Then simplify to get .25x - 2 = 28
Move the two to the right to get .25x = 30
Then divide to leave x: 30 / .25 = 120
X = 120
Answer:
A
Step-by-step explanation:
Answer:
$16
Step-by-step explanation:
she has $14 now
her parents let her earn 6
so $14 - $6 = $8
so thats what was left over from her allowance. she spent half of her allowance to get to $8 so you double the money
$8 * 2 = $16
$16 is her weekly allowance
Answer: an = 4 × 5^(n - 1)
Step-by-step explanation:
The given sequence is a geometric sequence because consecutive terms differ by a common ratio. The
formula for determining the nth term of a geometric progression is expressed as
an = a1r^(n - 1)
Where
a1 represents the first term of the sequence.
r represents the common ratio.
n represents the number of terms.
From the information given,
a1 = 4
r = 20/4 = 100/20 = 5
Therefore, the explicit formula for the sequence is
an = 4 × 5^(n - 1)
