Value of x is x=32
Step-by-step explanation:
We need to find the value of x of the equation 
Solving the equation and finding value of x
Adding 4 on both sides
Divide both sides by 0.5
So, value of x is x=32

Answer:
the answer is b
Step-by-step explanation:
The amount of medicine in the bloodstream decreases by 25% each hour.
<h3>Exponential equation</h3>
The standard exponential equation is expressed as:
y = ab^x
a is the initial amount
b is the rate
If b < 1, hence there is a declince
Given the expoenentia equation A(h)=600(0.75)^h,
b = 1 - r = 0.75
r = 1 - 0.75
r = 0.25
This shows that the amount of medicine in the bloodstream decreases by 25% each hour.

Oh no my answer i tooooooooooo short ok bye
its not c.
answer- b
Using a system of equations, it is found that it would take 2 servings of macaroni and 8 servings of broccoli to get the desired amount.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
- Variable M: Servings of macaroni.
- Variable B: Servings of broccoli.
Researching the problem on the internet, each serving of macaroni has 3 grams of protein, while each serving of broccoli has 2 grams. Since 22 grams of protein are needed, we have that:
3M + 2B = 22.
Each serving of macaroni has 16 grams of carbohydrates, while each serving of broccoli has 4 grams. Since 64 grams of carbohydrates are needed, we have that:
16M + 4B = 64
Simplifying by 4:
4M + B = 16 -> B = 16 - 4M
Replacing in the first equation:
3M + 2B = 22
3M + 2(16 - 4M) = 22
5M = 10
M = 10/5
M = 2.
B = 16 - 4M = 16 - 8 = 8
2 servings of macaroni and 8 servings of broccoli are needed.
