Answer:
Corresponding Angle
Step-by-step explanation:
Answer:
for the perimeter to be made into a equation it would take the equation
2(3x - 5) + 2(2x + 1)
And for the perimeter to equal 42 x would have to equal 5
Step-by-step explanation:
so first of all we have to find our equation to equal 42:
2(3x - 5) + 2(2x + 1) = 42
you then multiply 2 for both parentheses:
(3x * 2) + (-5 * 2) + (2x * 2) + (1 * 2) = 42
so its now:
6x -10 + 4x + 2 = 42
now your going to add variables to variables and numbers to numbers:
(6x + 4x) + ( -10 + 2) = 42
to get:
10x + (-8) = 42
Now your going to add 8 to both sides:
10x + (-8) = 42
+8 +8
Giving the equation:
10x = 50
now you divide both sides by 10 to get:
10x/ 10 = 50/10
x = 5
to solve you put 5 in place of the variable x:
2(3*5 - 5) + 2(2*5 + 1)
2(15 - 5) + 2(10 + 1)
20 + 22 = 42
So x equals 5 if the perimeter equaled 42
What is below the question is what I mean.
Answer:
10 students would spend $30.
Step-by-step explanation:
In order to find this, start by looking for the cost per student. We can do this by dividing the overall cost by the number of students.
$12/4 students = $3 per student.
Now we take that unit rate and multiply by the new number of students.
$3 * 10 students = $30 total spent.
Answer:
4*n^2 and n cannot equal 0
Step-by-step explanation:
First, since you have a variable int he denominator you need to write on the side that n cannot = 0, you may write it as n=/= 0, so a slash through an equal sign. You need to include this with your answer.
I'm assuming this is a fraction.The concept is actually pretty simple. What happens if you have 2/4? You can simplify it into 1/2. The concept is basically saying 2/(2*2) and here 2/2 = 1 so the 2 ont he top cancels out with one of the 2s on the bottom. This canceling only works for multiplication and division.
You can also do this with variables. x^3/x^7 can be rewritten as (x*x*x)/(x*x*x*x*x*x*x). here the three on top cancel out three ont he bottom leaving 1/(x*x*x*x) = 1/x^4. This also works if there are more on top. x^8/x^2 = x^6.
We do both in your problem. Let's work with one at a time. First the numbers. 32/4 = 8 Now the variables n^4/n^2 = n^2 because two of the ns int he numerator canceled the two in the denominator. Now put them together to have your answer. 4n^2 and you have to add that n=/=0
