WHAT !??
9.5 * sin (56o) = x
12 b = big box marbles
6(10-b) = small box marbles summed = 84
12b + 6(10-b) = 84
b = big boxes = 4 then little boxes = 10-4 = 6 little boxes
Remember sin = opposite / hypotenuse
sin 56o = x / 9.5
9.5 sin 56 = x take it from here !
120 + 98 = 218 218/2 = 109 in each to be equal
120 - 109 = 11 must move to theater 2 to be equal in number
Me too!
2 x + 3y = 21 slope = - 2/3 parallel slope is the same = - 2/3
slope calculation (y1-y2) / (x1-x2) ( it does not matter which point you assign 1 or point 2)
(17- -9)/ (j-2) = - 2/3
j = -37
p = pen cost 4p
n = pencil = 6-p cost = 2(6-p) summed = 20
4p + 2(6-p) = 20
p = 4 then n = 2
5 2
5 11
1111111
111112
11122
1222
six ways
Here is my solution: mostly remember that angles of a triangle sum to 180 and a straight line is also 180 degrees.
