Let

be the point on the ground to with the 18 foot guy is anchored and

the point on the ground to with the 21 foot guy is anchored.
We can conclude that the <span>the two wires at the points where they are anchored are
21 feet apart. Check the procedures in the picture attached.</span>
Answer:
6 times
Step-by-step explanation:
28claps =12seconds
? = 0.5minutes
60seconds=1minute
? =0.5 minutes
(cross multiply)
60*0.5/1 = ?
?=30seconds
28claps = 12secs
? =30secs
28*30/12 =?
?=70claps
Answer:
230 were sold at the door
170 were sold in advance
Step-by-step explanation:
x=at door y=in advance
x+y=400
3x+2y=1030
y=-x+400
2y=-3x+1030
y=-3/2x+515
-x+400=-3/2x+515
x=230 y=170
This is the function

Then factor 2 out

Divide both side by two and use the quadratic formula to get the following

X=3 And x=-2 and don't forget to Chek them
Do 1/3 x 7 (due to the parentheses which mean multiplication). Once you get that answer you should have 8/9 = x + (answer). Now subtract that answer from 8/9 and that's your x!
