Answer:
P = 15.42 cm
Step-by-step explanation:
Perimeter of circle = (πD/2)+D
Where D = 6 cm
P =( (3.14)(6)/2) + 6
P = (3.14)(3)+6
P = 9.4 + 6
P = 15.4 cm
3b - 7u -5
Add them together and put them in alphabetical order.
Y would equal to -5. hope this helps
We will need to have two equations here, having x as the missing length. We know that the chairs are in the same amount on each occasion, so each equation should be equal to the other.
This sets up a problem of:
6x + 7 = 4x + 13
7 and 13 being the leftover chairs and 6 and 4 being the rows. Let’s solve for x.
x = 3
Knowing this, we plug in x for one of the equations
6(3) + 7
18 + 7
25
Liam has 25 chairs.
