Answer:
C. 107 degrees
Step-by-step explanation:
First you take 135 then subtract it by 180 to find the missing angle. (a straight line is 180 degrees) then you get 45 and add it to 28. (If you add all the angles up in a triangle you get 180) then you subtract the 45+28 or 73 then subtract 180 by 73 and get 107 or C.
The formula is
A=p (1+r/k)^kt
A future value?
P present value 12000
R interest rate
T time
K compounding periods
The future value of 8 years in an account paying 5% compounded quarterly
A=12,000×(1+0.05÷4)^(4×8)
A=17,857.566103137 use it as a present value for the second period
at 6% compounded annually for an additional 6 years.
A=17,857.566103137×(1+0.06)^(6)
A=25,331.30....answer

Answer:
c. 10
Step-by-step explanation:
Eliminate parentheses using the distributive property.
3(b+4) -2(2b+3) = -4 . . . . given
3b +12 -4b -6 = -4 . . . . . parentheses eliminated
-b +6 = -4 . . . . . . . . . . . . collect terms
-b = -10 . . . . . . . . . . . . . . subtract 6
b = 10 . . . . . . . . . . . . . . . . multiply by -1

The rules of equality require that any operation you perform on one side of the equal sign must also be done on the other side. So when we say "subtract 6", we assume you know that means "subtract 6 from both sides of the equation", for example.
