Let x = total games played
16% = 0.16
0.16x = 40. Divide each number by 0.16.
x = 250

Hey there!!
Let us take the price of cinnamon tea as ' x ' and spice tea as ' y '
Now, let us take it into equation
12x + 3y = 15 -------------- ( 1 )
14x + 12y = 45 --------------- ( 2 )
Let us multiply the first equation with 4
48x + 12y = 60 --------------- ( 1 )
14x + 12y = 45 --------------- ( 2 )
Now, subtract equation 2
48x + 12y = 60
-14x - 12y = -45
Now, we get,
34x = 15
x = 15 / 34
This is the cost for cinnamon tea = $ 15 / 34
Now, substitute this into one equation
Let us take this equation - 12x + 3y = 15
Now, substitute ' x '
12 ( 15 / 34 ) + 3y = 15
6 ( 15 / 17 ) + 3y = 15
90 / 17 + 3y = 15
3y = 15 - 90/17
3y = 165 / 17
y = ( 165/17 ) ( 1 / 3 )
y = $ 55/17
Cinnamon tea = $ 15/34
Spice tea = $ 55/17
Hope helps!
By the Triangle Angle-Sum Theorem, all the angles in a triangle have to add up to equal 180. Therefore, 180-35-88=57, second choice down.
the answer is 888829299293
Answer:
z = 92
x = 11
Step-by-step explanation:
From the figure,
13x - 55 = 88 (Opposite angles made by two straight lines are equal)
13x = 88 + 55
13x = 143
x = 143/13
x = 11
Again,
88 + z = 180 (Sum of angles of a straight line)
z = 180 - 88
z = 92
