Answer:
it's 2.45
Step-by-step explanation:
because 24.50 divided by ten is 2.45
Answer: 24
Step-by-step explanation:
So, let's begin...
First off, you must note that the question is asking for the d value when you substitute the value of c(x).
You are given the following information:
1. The c(x) value is already given to be 0.75x.
2. The equation to find d of (any value) is 0.8y-5.
So, substitute the value of 0.75x as a y value into 0.8y - 5. This is because you are substituting the value of c(x) for d. This is equal to 0.8 times 0.75x - 5. This is equal to 0.6x - 5, which is the function. Thus, your final answer is d(c(x)) = 0.6x - 5.

Answer:
x = 6
Step-by-step explanation:
We can see that the the 32 degree angle plus the equation (9x + 4) is equal to 90 degrees.
We know this because the bottom line is a 180 degree angle, and we can see on the other side that it is a right angle.
If we were to turn that into an equation it would like like this:
(9x + 4) + 32 = 90
Now you just have to solve for x.
9x + 4 + 32 = 90
Combine like terms:
9x + 36 = 90
Subtract 36 from both sides
9x = 54
divide both sides by 9
x = 6
and you are left with the answer.
