We set up a proportion: 14/?= 1/5
Cross multiply: 1*?= 14*5
⇒ ?= 14*5/1= 70
1/5 of 70 is 14.
Answer:
there were 200 children and 500 adults at the show
Step-by-step explanation:
7x+10y=6400
x+y=700
x=700-y
7(700-y)+10y=6400
4900-7y+10y=6400
-7y+10y=1500
3y=1500
y=500
x=700-y
x=700-500
x=200
Length of shorter piece is 13 ft
Length of longer piece is 61 - 13 => 48 ft
I'm guessing that the >= is a greater than or equal to sign, so the answer should be d>=2 and d<2, please tell me if I am wrong and I will do my best to correct it!
