How do i solve 20=5x+10y

1 answer:

3 0

To solve for y you'll want to set x equal to 0
So the equationl is 20=5(0)+10y
Distribute the five and the equation becomes
20=0+10y or
20=10y

Then divide each side by 10 to isolate y
20/10=2
10y/10=y

So y=2

John invested $740 in an account paying an interest rate of 6.7% compounded monthly. Assuming no deposits or withdrawals are mad

Marianna [84]

Answer:

The amount which will be in account after 6 years is $ 1120 .

Step-by-step explanation:

Given as :

The principal in the account = $740

The rate of interest = 6.7 % compounded monthly

The time period = 6 years

Let the Amount in the account after 6 years = A

From compound interest method

Amount = Principal × $(1+\dfrac{\textrm Rate}{12\times 100})^{12\times \textrm Time}$

Or, A = $ 740 × $(1+\dfrac{\textrm 6.7}{12\times 100})^{12\times \textrm 6}$

Or, A = $ 740 × $(1.0058)^{72}$

or, A = $ 740 × 1.5164 = $ 1122.136

Hence The amount which will be in account after 6 years is $ 1120 . Answer
