Answer:
11. X=76
Step-by-step explanation:
6:5 to 24:20
thats because 6 to 24 is 4 times so you do 5 times 4 and get 20.
Answer:
1.50
Step-by-step explanation:
X = hot dog price
Y = hamburger price
5X + 4Y = 16.50
4X + 5Y = 17.25
4(5X + 4Y = 16.50)
20X + 16Y = 66
5(4X + 5y = 17.25)
20X + 25Y = 86.25
Now subtract the equations:
20X + 16Y = 66
20X + 25Y = 86.25
9Y = 20.25
Y = 2.25
Hamburger is $2.25
4X + 5(2.25) = 17.25
4X + 11.25 = 17.25
4X = 6.00
X = 1.50
Hamburgers are $2.25
Hotdogs are $1.50
Answer: 3/5 inches
Step-by-step explanation:
l= 5w+7
A = wl
w(5w+7) = 6
5w²+7w = 6
5w²+7w -6 = 0
5w²+10w-3w-6=0
5w(w+2)-3(w+2)=0
(5w-3)(w+2)=0
5w-3=0 w+2=0
5w=3 w=-2in
w=3/5in
width cannot be negative, so the width is 3/5 inches.
