Greeting Card = 3.79
Total Cost = 5.11
Post cards = x
Equation
Total Cost = Greeting Card + 4x
Solution
Substitute the gives into the equation
5.11 = 3.79 + 4x Subtract 3.79 from both sides
5.11 - 3.79 = 3.79 - 3.79 + 4x Combine
1.32 = 4x Divide by 4
1.32/4 = 4x/4
x = 33
Each post card costs 0.33 dollars
Answer:
C
Step-by-step explanation:
A) not true. Sin A = some decimal
Cos 720 = 1
D) That means that d is not true either. not true
B) Sin55 = cos55 is not true either only sin(45) = cos(45) is true. So B is not true.
That leaves C. I think if you check it, you'll find it is right. sin(A) = cos(90 - A)
Answer:
Step-by-step explanation:
Alright, lets get started.
The given equation is :
If we divide the equation with -2 in both sides
Subtract 3 in both sides
So, the first step of simplifying equation is divide equation with -2. : Answer
