Is 1 x7 positive or negative

1 answer:

4 0

Not sure if I quite understand your question. But ill assume that you're asking if 1 times 7 is positive. Or if 1x7 is positive.

1 times 7 equals 7 so it is a positive integer.

1x7 can be positive or negative depending on what x equals. If x is a negative number then the whole expression is negative. If x is postive the expression is positive.

Tammy deposited $520 in the bank account that earns simple interest every year after 5 years she had earned $156 and interest if

aleksley [76]

Answer:

6%.

Step-by-step explanation:

We have been given that Tammy deposited $520 in the bank account that earns simple interest every year after 5 years she had earned $156.

To find the interest rate we will use simple interest formula.

$I=P*r*T$

I= Interest.

P= Principal amount.

r=Annual interest rate (in decimal form).

T= Time in years.

We have been given that I=156, T=5, P=520

Upon substituting our values in above formula we will get,

$156=520*r*5$

$156=2600r$

$r=\frac{156}{2600}$

$r=0.06$

Let us multiply 0.06 by 100 to convert annual interest rate in percentage.

$0.06*100=6 \text{ percent}$

Therefore, the annual interest rate was 6%.
