Answer:

x=91

Step-by-step explanation:

Since these angles are same side exterior angles, they will add to 180 degrees. Therefore:

(x-3)+(x+5)=180

Drop the parentheses.

x-3+x+5

Combine like terms.

2x+2=180

Subtract 2 from both sides.

2x=178

Divide both sides by 2.

x=89

Answer:

x=89

Step-by-step explanation:

Okay so. because of the rules of parallel lines and their intersecting lines, we know that the upper angle and the lower angle are complimentary angles. This means that they add up to equal 180 degrees.

Because of this, we know that (x-3)+(x+5)=180

2x+2=180

2x=178

x=89

1615/170 simplify show work

Sloan [31]

1615/170

We first need to convert this into a proper fraction. Which means that the denominator must be larger than the numerator for it to be proper. Also, since 1615 is BIGGER than 170, we will end up with a mixed fraction. A mixed fraction always has a whole number.

1615 can go into 170 how many times?

9 times

170*9 = 1530

Now subtract.

1615 - 1530 = 85

Now we have our mixed fraction: 9 85/170

Now we must simplify the fraction.

85/5 = 17
170/5 = 34

17/34 is the smallest possible fraction we can get.

9 17/34

Final answer: $9 \frac{17}{34}$

Calculate the future value in five years of $8,000 received today if your investments pay future value a. 5 percent compounded a

zhannawk [14.2K]

The Future value is:

a) $10,210.25

b) $11,220.41

c) $12,308.99

d) $18,938.90

e) $44,835.28

What is future value?

The future value (FV) of any asset can be understood as an increase in its value at a fixed rate over a period of time. For a given principal sum P, rate of interest r, and time period t, the future value of an asset can be calculated as:

FV=P*(1+r) ^t

We can find future value as shown below:

P=$8,000

t=5 year

a) r=6%=0.06

FV=8000*(1+0.05) ^5

=8000*(1.0) ^5

=$10,210.25

b) r=7%=0.07

FV=8000*(1+0.07) ^5

=8000*(1.07) ^5

=$11,220.41

c) r=9%=0.09

FV=8000*(1+0.09) ^5

=$12,308.99

d) r=9% compounded semiannually

= 0.09

t=2*5=10

FV=8000*(1+0.09) ^10

=8000*(1.09) ^10

=$18,938.90

e) r=9 percent compounded quarterly

=0.09

t=5*4=20

FV=8000*(1+0.09) ^20

=8000*(1.09) ^20

=$44,835.28
