I really dont know
Step-by-step explanation:
The solution is:
.1*50+x=.25(50+x) 5+x= 12.5+ .25x
x-.25x=12.5-5 .75x=7.5 x=7.5 or .75
Answer:
$8100
Step-by-step explanation:
There are 36 months in 3 years.
225 x 36 = $8100
It is 3.
You can check this by seeing 3^3 ie. 3x3x3, which comes out as 27.
You can check the cube root on a calculator.
To find the common ratio in a geometric sequence, u divide the second term by the first term. 20/80 = 1/4 <== common ratio
Terms are found in a geometric sequence by multiplying each number by the common ratio to get to the next number.
start with 80
80 * 1/4 = 80/4 = 20
20 * 1/4 = 20/4 = 5
5 * 1/4 = 5/4
5/4 * 1/4 = 5/16 <===
5/16 * 1/4 = 5/64 <===
5/64 * 1/4 = 5/256 <===
