The answer is on the paper
They would be parallel lines
Answer: The equation is 5x = 125
Step-by-step explanation:
A pentagon is a five sided figure so all the side lengths must be equal. And to find the perimeter of a pentagon the you will the five equal side lengths.
So assume we don't know the side lengths so we will represent it by x and the side lengths are 5 so we will have five x's and they will add up to 125 and that could be represent by the equation.
x + x + x + x + x = 125
5x = 125
x = 25
Answer:
Step-by-step explanation:
Let shakes be s and hamburgers be h. Then the total cost equation would be
2s + 3h = 17
The next equation in our system will be
3s + 4h = 24
You can solve this by either substitution or elimination. I'm going with substitution because it's easier in this platform to do so. I'm going to solve the second equation for h.
4h = 24 - 3s and
h = 6 - .75s
Now we will sub that into the first equation to get
2s + 3(6 - .75s) = 17 and
2s + 18 - 2.25s = 17 and
-.25s = -1 and
s = 4
That means that shakes cost $4 each. Now plug in 4 for s and solve for h:
h = 6 - .75(4) and
h = 6 - 3 so
h = 3 so hamburgers cost $3 each.
Just add the vi/t to both sides. vf=a+vi/t
