Answer:

10,074

Step-by-step explanation:

1000-3000= -2000

-2000 + 74 = -2074

-2074 + 1000 = 1074

-1074 - 3000 = 4074

-4074 - 5000 = -9074

-9074 -1000 = 10,074

Which steps show how to use the distributive property to evaluate 6 times 49

lina2011 [118]

Answer:

294

Step-by-step explanation:

The distributive property for multiplication is as follows :

a(b+c) = ab + ac

We need to evaluate 6 times 49 i.e. 6(49).

We can write 49 as (50-1)

6(50-1) = 6(50+(-1))

Here, a = 6, b = 50 and c = -1

So,

6(50+(-1)) = 6(50) + 6(-1)

= 300-6

= 294

So, answer is 294. Option (A) is somehow correct.

what was the interest rate if your balance on an investment of 857 dollars at the end of six years is 1268.36 dollars

Mumz [18]

<h3>The interest rate is 8 % if your balance on an investment of 857 dollars at the end of six years is 1268.36 dollars</h3>

<em><u>Solution:</u></em>

Given that,

Principal = $ 857

Amount = $ 1268.36

Number of years = 6

Rate of interest = ?

Simple Interest = Amount - principal

Simple Interest = 1268.36 - 857

Simple Interest = 411.36

<em><u>Use the formula,</u></em>

$Simple Interest = \frac{ p \times n \times r}{100}\\\\411.36 = \frac{ 857 \times 6 \times r}{100}\\\\41136 = 5142 \times r\\\\r = \frac{41136}{5142}\\\\r = 8 \%$

Thus the interest rate is 8 %
