Answer:
95
Step-by-step explanation:
Let x represent the cost of adult tickets for $16
Let y represent the cost of children tickets for $6
x + y = 137...........equation 1
16x +6y = 1772............equation 2
Multiply equation 1 by 16 and equation 2 by 1
16x + 16y= 2192
-
16x + 6y = 1772
10y = 420
y= 420/10
y= 42
Substitute 42 for y in equation 1
x + y = 137
x + 42= 137
x = 137-42
x= 95
Hence 95 adult tickets were sold for $16 and 42 children tickets were sold for $6
Since 1 is positive, then D would be your answer.
Answer:
Step-by-step explanation:
This actually happened to me. I was walking out of a national forest and came up to a stream that I had not crossed. I got my bearings confused and realized I was lost. I knew that if I went Northwest it would be about a 30 mile hike out in heavy woods, with obvious other streams to cross. In the Southeast direction, it would only be about 5 miles.
The sun was out but mostly overhead and no help with directions.
I couldn't wait until the sun went farther West to get my directions. It was a warm Winter day but I wasn't dressed to be there after dark when the temperature fell, even if I did go in the correct direction.
I stuck a stick in the ground and made a mark in the dirt at the end of it's shadow. I sat down for about 15 minutes, then made a new mark in the dirt at the end of the sticks shadow again. I drew a line in the dirt to connect the two marks. This line ran close to the East/West direction, the first mark being the West direction.
I made it out about 5 PM just as the sun was disappearing through the trees.
Wdym “these are the right answers”..?
