Answer:
C
Step-by-step explanation:
Answer:
1)
<u><em>k - 5 = m</em></u>
<u><em>n - 3 = s</em></u>
2)
<u><em>Lisa is 17 and Myra is 12</em></u>
__________________________________________________
<u><em>1) </em></u>Key:
brother = b
me = m/n
sister = s
Equation:
m + 5 = b
m - 3 = s
Answer:
b - k = m
n - 3 = s
<u><em>2)</em></u>
L + M = 19
(L + 5) + M = 29
(L + 5 - 5) + m = 24
L + M = 24 / 2 = 12
L = 12 + 5 = 17
M = 12
Lisa will be 17 and Myra is 12
Answer:
614.25
Step-by-step explanation:
The amount of interest is computed using ...
... I = Prt . . . . . where P is the principal amount, r is the annual interest rate, and t is the number of years.
Here, the interest is ...
... I = 520×0.075×(2 5/12) = 39×29/12 = 94.25
The total amount due, interest plus principal, is ...
... 94.25 + 520 = 614.25

Convert degrees to radians, multiply by π/180° , since a full circle is 360 ° 360 or 2π radians.
− 405°⋅ π /180° radians
Cancel the common factor of 45 .
-9 ⋅ π/4 radians
Combine −9 and π/4
-9π/4
Move the negative in front of the fraction.
-9π/4 radians
