Answer: The equation 60 + x= 3x -70 could be set up to solve for x.

Step-by-step explanation:

The two remote interior angles sums will equal to the exterior angle .

Meaning that angle 60 plus angle x has to equal to angle 3x -70.

60 + x= 3x -70 Now solve for x by adding 70 to both sides

+70 +70

130 + x = 3x Now subtract x from both sides

-x -x

130 = 2x Divide both sides by

x = 65

Answer:

After 9 years the account will be worth 13709.60$

Step-by-step explanation:

We are given the following in the question:

We are given the following in the question:

P = $8000

r = 6% = 0.046

n = 12

The compound interest is given by:

$A = p\bigg(1+\dfrac{r}{n}\bigg)^{nt}$

where A is the amount, p is the principal, r is the interest rate, t is the time in years.

Putting the values, we get,

$13709.60 = 8000\bigg(1+\dfrac{0.06}{12}\bigg)^{12t}\\\\\dfrac{13709.60}{8000} = \bigg(1+\dfrac{0.06}{12}\bigg)^{12t}\\\\\Rightarrow 1.7137 = (1.005)^{12t}\\\Rightarrow t \approx 9$

Thus, after 9 years the account will be worth 13709.60$

Write 4 3/7 as a decimal.

Citrus2011 [14]

Hi!

There are two ways to do this.

1. Start with the first part of the decimal, (4.) then divide 3/7 to get the second part.

3/7 = 0.43

4.43

2. Convert the mixed number 4 3/7 to a fraction.

4 x 7 = 28
28 + 3 = 31

31/7

Now convert that into a decimal.

31/7 = 4.43

The answer is 4.43

Hope this helps! :)
