Answer:

To solve, use a simple one-step equation

Known: Number of coins; Number of Nickles.

Unknown: Number of Dimes.

a) To find the number of Dimes

b) Use x (or virtually any letter) to represent the unknown number of dimes

c) 9+x=13

d) Subtract 9 from both sides to cancel out the 9 and isolate the variable on one side. x=4

e) 9+4=13, so yes, the answer is correct

Mario invests 1,500 in a savings account that earns 2% interest a year. He also plans to set aside $50 cash a month. A:2100(1.02
Sedbober [7]

Answer:

<em>1500(1.02)^x  +   600x</em> is how much he has in savings at the end of x years where it be in the bank or elsewhere

Step-by-step explanation:

x is in years

Let's just think about the investment of 1500 in an account earning 2% per year.

Before the years even start, you are at 1500 ( present value).

The next year (year 1), it would be 1500*.02+1500=(1500)(1.02).

The next year (year 2), it would be 1500(1.02)(.02)+1500(1.02)=1500(1.02)(1.02).

We keep multiplying factors of (1.02) each time.

So for year x, you would have saved 1500(1.02)^x.

Now we are saving 50 cash per month. Per year this would be 12(50) since there are 12 months in a year.  12(50)=600.  

So the first year you would have 600.

The second year you would have 600(2) or 1200.

The third year you would have 600(3) or 1800.

Let's put this together:

1500(1.02)^x  +   600x

What is the answer 101/8+(35/8+27/8
suter [353]

Answer:

\frac{163}{8}

Step-by-step explanation:

The sum already has common denominators so there is no need to change the denominators. Just add the numerators.

\frac{35}{8} + \frac{27}{8} = \frac{62}{8}

\frac{101}{8} + \frac{62}{8} = \frac{163}{8}
