The amount of degrees in a polygon: 360

In a pentagon: 360 / 5 = 72

9x - 18 = 72     Add 18 to both sides

9x = 90               Divide by 9

x = 10

Sumara Kato's savings account has a balance of $1663. After 19 years, how much interest
lesantik [10]

Answer: $2936.27

Step-by-step explanation:

Present value = $1663

Rate = 5.5%

Time(n) = 19years

Future value= PV(1+r)^n

= 1663(1+5.5%)^19

= 1663(1.055)^19

=1663 × 2.766

=4599.86

Interest = Future value - Present value

= $4599 - $1663

= 2936

3/4 + 1/2
multiply 1/2 denominator and numerator by 2 to match 3/4
= 3/4 + 2/4 = 5/4 (copy same denominator add numerator)

2/6 + 1/3
divide 2/6 denominator and numerator by 2 to match 1/3
= 1/3 + 1/3 = 2/3 (copy same denominator add numerator)

5/9 + 2/3
multiply 2/3 denominator and numerator by 3 to match 5/9
= 5/9 + 6/9 = 11/9 (copy same denominator add numerator)



6/9 -1/5
cross multiply 6x5 - 1x9 for numerator
for denominator multiply 9x5
=30/45 - 9/45= 21/45
divide num and den by 3
=7/15

<h3><u>Explanation</u></h3>
  • Given the expressions and values.

\frac{2ab +  {a}^{2}  {b}^{2}  - a}{ab}  \\  \begin{cases} a  =  - 1 \\ b = 1 \end{cases}

  • Substitute the value of a and b in the expression to evaluate.

\frac{2( - 1)(1) +  {( - 1)}^{2}  {(1)}^{2}  - ( - 1)}{( - 1)(1)}

  • Evaluate

\frac{2( - 1) + 1(1) + 1}{ - 1}  \\  \frac{ - 2 + 1 + 1}{ - 1}  \\  \frac{ - 2 + 2}{ - 1}  \\  \frac{0}{ - 1}  \Longrightarrow 0
