<span>Find
the number of bluejays bird and robins birds as joan counted it
=> the number of Robins is twice as bluejay
=> Robins = 2X
=> The number of bluejay is about to know:
=> Bluejay = X
The total number of birds is 21.
=> 2X + X = 21
=> 3x = 21
=> 3x / 3 = 21 / 3
=> x = 7
Thus the number of bluejay is 7
=> Robin = 2(7)
=> Robin = 14
Thus the number of Robin is 14</span>

the question is blurry, please resend it
Given:
Unit base price: $435
Credit Card interest rate, i = 9.4% compounded monthly; i = 0.00783/month comp monthly
n = 1.5 years = 18 months
sales tax = 8.51%
First, determine the actual price of the unit by adding the sales tax to the base price of the unit:
$435 * (1 + 0.0851)
Actual price = $472.0185
So, the total amount paid by Brian should be higher than the actual price since he used his credit card. Use the formula from economics:
F = P (1+i)^n
F = $507.96
Therefore, the total amount paid by Brian is $507.96.
Answer:
2. RS ≅ ST (Definition of midpoint).
- Definition of midpoint states that the point shared by both line segment (in this case, S, is your mid point, and that (in this case, R & T), are end points.
4. RS ≅ XY (Transitive Property of Congruence).
Transitive Property of Congruence state that if you know that, for example, XY ≅ RS, & ST ≅ RS, therefore, XY ≅ ST (Transitive Property).
