Answer:

W and Y = 91. X and Z = 89

Step-by-step explanation:

Those two angles will add to 180.

5a - 21 + 3a + 25 = 8a + 4

8a + 4 = 180

8a = 176

176 / 8 = 22 = a

Plug in a for an angle.

3(22) + 25 = 91

180 - 91 = 89

3a+b=63
5a+4b=140
So
12a+4b=252
5a+4b=140
7a=112
a=16

The value of a jewel in 2015 was $17500. The jewel was purchased in 2008, and its value appreciated 2.5%

ArbitrLikvidat [17]

Answer:

$14722.14

Step-by-step explanation:

We are given that

In 2015

The value of jewel=$17500

Rate of appreciation, r=2.5%

We have to find the initial value of the jewel when it was first bought.

Time, n=7 years

Final value= $Initial\;value (r/100+1)^n$

Using the formula

$17500=Initial\;value(2.5/100+1)^7$

$17500=Initial\;value(1.025)^7$

$Initial\;value=\frac{17500}{(1.025)^7}$

Initial value=$14722.14

Hence, the the initial value of the jewel when it was first bought=$14722.14
