Answer:
x = 2, y = 1
Step-by-step explanation:
x + 4y = 6 and y = 3 - x have to be rearranged: x + 4y = 6 and x + y = 3
You subtract the equations to eliminate one of the variables (x) so that the other can be found
Answer: he should invest $16129 today.
Step-by-step explanation:
Let $P represent the initial amount that should be invested today. It means that principal,
P = $P
It would be compounded annually. This means that it would be compounded once in a year. So
n = 1
The rate at which the principal would be compounded is 7.6%. So
r = 7.6/100 = 0.076
The duration of the investment would be 6 years. So
t = 6
The formula for compound interest is
A = P(1+r/n)^nt
A = total amount in the account at the end of t years.
A = 25000
Therefore
25000 = P(1+0.076/1)^1×6
25000 = P(1.076)^6
25000 = 1.55P
P = 25000/1.55
P = $16129

Answer:
22 cm
Step-by-step explanation:
Simply count the number of square units of each side, then add them up. (each square unit = 1 cm)
4+4+2+3+2+7
= 22 cm
Answer: #64, A. #67, A. #68, C
Step-by-step explanation:
#64
0.96/6= 0.16
2.4/16= 0.15
32= 0.18
16 oz is the least
#67
100/20=5
3*5=15
SO, it's 15%.
#68
Divide
$430/43= $10
$594/54= $11
Andrew= $8
So, Darren makes the most.
