Answer:
the value of the investment after 3 years= £11,904
Step-by-step explanation:
sarah invests £9600 at a simple interest rate of 8% per year
number of years = 3
Formula for simple interest
I = P*n* r
P is the initial amount invested= 9600
r is the rate of interest = 8% = 0.08
n = number of years = 3
Now we find interest using formula
I = 9600 * 0.08 * 3= 2304
Interest amount is 2,304
Now we add the interest with the initial amount to get the value of investment after 3 years
9600 + 2304= 11904
Answer:
16,000,000
Step-by-step explanation:
to start off your going to need to use PEMDAS (parenthesis exponents multiplication division addition subtraction)
so we are going to start IN the parenthesis the next step is doing the exponents so its going to look like this 1,000,000
rewrite the problem: 4(4×1,000,000)
use the next step in PEMDAS multiplication rewrite the problem:
4(4,000,000)
multiply: 16,000,000

From the list of given options, the option that answers the question is
Step-by-step explanation:
Hey, there!
Here,
Given that:
we need to find factor,
As it is in a^2-b^2 form as per its factor (a+b) (a-b), keeping same formula here,
25x^2 means (5x)^2
and 4 means 2^2
Now, it would be,
Therefore, it's factor would be (5x+2)(5x-2).

4s+7a=861
s+a=168
This can be solved using either elimination or substitution. I am going to use substitution.
Solve s+a=168 for s
s=168-a
Replace 168-a for s in 4s+7a=861
4(168-a)+7a=861
672-4a+7a=861
Solve for a
672+3a=861
3a=189
a=63
Substitute 63 for a in s=168-a
s=168-63=105
So, s=105 student tickets and a=63 adult tickets
