Answer:
x=5
Step-by-step explanation:
we can see:
20 inches= x +3x
x?
so we have
20=4x
x=20/4
x=5
Answer
I attach the image of the circle in the picture below
Circumference larger circle = 62.831 in
Step-by-step explanation:
The perimeter of a circle is defined as
P = 2* pi* r
where
r corresponds to the radius of the circle.
In this case,
r = d/2 = 3 in
The perimeter of the smaller circle results
P1 = 2*(3.1416)*(3 in) = 18.8495 in
The circumference of the smaller circle is 30% of the circumference of the larger circle, so
P1 = 0.3* P2
P2 = 18.8495 in / 0.3 = 20
= 62.831 in
Answer:
it could be y = 10 or y = 9 then X
Step-by-step explanation:
if im wrong then im sorry
150x + 400(1900-x) = 440250
150x + 760000 - 400x = 440250
250x = 319750
x = 1279
There were 1,279 children.
Y=-3x-1
bc the y intercept is -1 and the slope is -3
