Answer:
300 Adults 555 Children
Step-by-step explanation:
What we know:
Firstly, at 5pm there were 36 more Children (C) than Adults (A)
So.....C = A + 36
Secondly, at 12pm there were 5 x more Children and 4 x more Adults and the total was 855
So 4A + 5C = 855
——-
Now use ‘C = A + 36’ and get rid of all ‘C’ in the second equation.....
4A + 5C = 855
becomes......
4A + 5 (A + 36) = 855
Multiply the brackets (5 x A) and (5 x 36):
4A + 5A + 180 = 855
Take off 180 from both sides:
4A + 5A = 675
Therefore 9A = 675
Divide by 9:
A = 75
We know C is A + 36
C = 111
At 5 pm - A = 75 and C = 111
Therefore at 12:
There were 5 x C = 555
And 4 x A = 300
Answer:
8π
Step-by-step explanation:
If we are given the diameter of this circular fence, then we can solve for the radius. Just take the diameter of 4 and divide by 2 which is 2.
The circumference of a circle is 2πr²
Just plug in the variables and you get 2π(2)² which is 8π
Hope this helps! :)
Recall the slope intercept form of an equation is:
y = mx + c, where m is the slope and c = vertical intercept.
y + 2 = 5x + 4
y + 2 = 5x + 4
y = 5x + 4 - 2
y = 5x + 2
So the slope intercept form is y = 5x + 2
Hope this helps.
Answer:
Step-by-step explanation:
Add 
to both sides:
Subtract 2 from both sides:
Divide both side by 2:
Answer:
5 weeks
Step-by-step explanation:
319.50-21.95=297.55
297.55/63.00=4.72
Since he can't wait for those many weeks, you would round it to 5 so he has enough money
