Answer:
Make an eqaution from here.
Let’s make evening 2 “x”
So the first evening has 9 less then the secon evening so…
x-9
Of course theres the second evening (x).
X-9+x
Then the third evening has 4 times as much as the second meeting so…
x-9+x+4x
And when solved, it has to equal 105.
So solve from here.
Combine like terms.
6x-9=105
Isolate
6x=114
x= 19
First evening is 9 less then 19, so 10.
The second evening was 19 calls.
The third evening was 4 times the second evening so, 19*4= 76
1st night = 10
2nd night= 19 calls
Thrid night= 76 calls
The explanation is:
The definition of "secant of (x)" is: 1 / (sine of x) .
"Square inches" means area, so 60" wide and 3 feet long is multiplied, however, they have to be in the same unit. So, 3 feet = 36 inches since 1 foot is 12 inches and 3(12) = 36.
Therefore, 60 inches * 36 inches = 2,160 square inches of fabric.
