Standard form means, move the variables to the left-hand-side and leave the constant all by herself on the right-hand-side, usually sorting the variables, so"x" goes first.
now, there's a denominator, we can do away with it, by simply multiplying both sides by the denominator, so let's do so,
Step-by-step explanation:
previous =£400
present=£504
percentage=(£504-£400)/£504*100
=104/£504*100
=20.63%
Answer:
x= 8
y= -5
z= 0
Step-by-step explanation:
this is the correct answer to this system of equations.
5*23
Note 23 = 20 + 3
5*23 = 5*(20 + 3) and by distributive property
5*23 = 5*20 + 5*3 = 100 + 15 = 115
= 115
Answer:
The amount in account after 7 years of investment is $1478.4
Step-by-step explanation:
Given as :
The principal invested in account by Jamie = p = $1200
The rate of interest = r = 3% compounded annually
The Time period of investment = t= 7 years
Let The Amount in Jamie account = $ A
<u>For continuous compounding</u>
Amount = Principal × 
Or, A = p ×
Or, A = $1200 × 
Or, A = $1200 × 
Or, A = $1200 × 1.232
∴ A = $1478.4
So, The amount after continuous compounding = A = $1478.4
Hence , The amount in account after 7 years of investment is $1478.4 Answer
