Answer:
b + g = 25
b = g + 3
Step-by-step explanation:
Let b = number of boys.
Let g = number of girls.
"Mrs. Smith has a total of 25 kids in her class."
b + g = 25
"There are 3 more boys than there are girls."
b = g + 3
The system of equations is:
b + g = 25
b = g + 3
Answer:
<h2>The answer is 3</h2>
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
where
(x1 , y1) and (x2 , y2) are the points
From the question we have
We have the final answer as
<h3>3</h3>
Hope this helps you
The given equation is:
(8+3a) * a
To get the value at a=1/3, we will substitute the value of a in the given equation with 1/3 and compute the result as follows:
(8+3(1/3)) * (1/3)
(8+1)*(1/3)
(9) * (1/3) = 3
Answer:
f(x) = 2+2*x where x is the miles you run
Step-by-step explanation:
Lets call f(x) the function that show how much money the sponsor will give you as a function of the miles you walk (x). If you do not walk any mile you have only $5, then if you walk one mile you get $5+$2=$7, and so on. Lets use a simple table for some values (I will omit $ symbol for simplicity):
x (miles) f(x) (money)
1 5+2
2 5+2(2) = 9
3 5+3(2) = 11
10 5+10(2) = 25
x 2+2*x
So we can observe a pattern, the total payment you receive will be 5 plus the miles you run multiplied by 2. Thus the expression for the total amount you will collect from your sponsor at the end of the walk a thon is:
f(x) = 2+2*x
where x is the miles you run.
I hope it is understandable.
