The perimeter is the sum of all side lengths of a given shape, and can be computed by adding up all of the side lengths.
So in this case, it would be 15 x 2 + 13 x 2 the sum of them would be equal to the perimeter of the object, I believe.
Answer:
10
Step-by-step explanation:
because there are 20 girls and 10 boys = 30
The point P has coordinates (x,y) = (-2,6) so x = -2 and y = 6
Replace x and y with those values into the rule given
So,
(x,y) ---> (x-2, y-16)
turns into
(-2,6) ---> (-2-2, 6-16) = (-4,-10)
P = (-2,6)
P ' = (-4,-10)
The answer is -10 because your teacher just wants the y coordinate of point P'
Answer:
900
Step-by-step explanation:
you just see if by the number, if the number is 6 and up your round over and it would become 950 but the number is lower so you make it 900.
