In one tray, we have 1/5. Since one is purple out of the 5 colors.
So in 20 trays, we have:
(1/5) x 20 = 20/5 = 4
The value of x given that the sum of exterior angle is 360 is 27
<h3 /><h3>Sum of exterior angle of a pentagon </h3>
Sum of exterior angle of a pentagon is 360°. Taking the sum of the angles and equating to 360 degrees, we will have:
2x - 20 + 2x + 50 + 3x + 10 + 3x + 50 = 360
Collect the like terms
10x + 90 = 360
Subtract 90 from both sides
10x + 90 - 90 = 360 - 90
10x = 270
x = 27
Hence the value of x given that the sum of exterior angle is 360 is 27

Answer:
she invested 6600 at 3% and 3400 at 2.5%
Step-by-step explanation:
Simple interest = amount deposited x time x interest rate
Let the amount deposited in in the account bearing 3% interest by represented with a
Let the amount deposited in in the account bearing 2.5% interest by represented with (10,000 - a)
a x 0.03 + (10,000 - a) x 0.025 = 283
0.03a + 250 - 0,025a = 283
collect like terms
0.03a - 0.025a = 283 - 250
0.005a = 33
a = 6600
the amount deposited in the 2.5% account = 1000 - 6600 = 3400
