Answer:
The answer is: Number of adult tickets: 20. Number kid's tickets: 50.
Step-by-step explanation:
5.50a + 4.00k = 310
a + k = 70
a = 70 - k
5.50(70-k) + 4.00k = 3.10
385 - 5.5k + 4k = 310
-1.5k = 310 - 385
-1.5k = -75
k = -75 / -1.5 = 50
Find the number of adult tickets:
a + 50 = 70
a = 20
Proof:
5.50(20) + 4.00(50) = 3.10
110 + 200 = $310
1)2(m+3)=-6
2m+6=-6
2m=-6-6
2m=-12
M=-12/2=-6
2)2m+6=-6
2m=-6-6
2m=-12
M=-12/2=-6
3)2m+6-6=-6-6
2m=-12
M=-12/2=-6
4)2m=-12
M=-12/2=-6
Answer:
hello
we can think like the hamburger is all equal to 100.
if the first bite was %20 of the hamburger, we can say there left 80. because 100×20/100 its = 20 and 100-20= 80. the problem is not this i wanna say. there was a teory similar like this problem.
a girl was going to her home. in every step she was going 2/1 of the road.. it was impossible to arrive to home.
we said 100 for all hamburger right?
it would be 0,0000000100 too..
so if we continued to dividing by %20 everytime, we never had a result of it.
maybe at least we found 0,0000000000001.
And? then we had to found 0,0000000000001's %20.
soo, the problem's answer is its not possible.
good luck(: (sry for nub eng)
1 inch = 2.54 centimeters
1 foot = 12 inch
1 inch = 2.54 cm
12 inch = 12times 2.54 cm = 30.48 cm
Answer 1 foot = 12 inch = 12times 2.54 = 30.48 cm
* we know 1 yard = 3 foot
1 foot = 12 inch
1 inch = 2.54 cm
Answer : so 1 yard = 3 foot = 3* 12 inch = 36 * 2.54 cm =91.44 cm
the answer is 20 because 20/10=2 and 2*10 is 20 so that is why 20 is your answer
