To solve, you just set the first equation equal to x, so x=34+y. Then you plug 34+y in for x on the second equation, giving you (34+y)+y=212.
Then simplify to 34+2y=212.
Minus 34 on both sides to get 2y=178.
Then solve for y, substitute that value into the first equation, and then solve for x.
Answer: 160 chicken sandwiches were sold.
To convert a percentage into a decimal, move the decimal two places back.
40%=0.40, or 0.4
This means that 0.4 is still equivalent to 40%
Remember that "of" means multiplication.
So 0.4*400=160
160 chicken sandwiches were sold
Sin35= x/20
x = sin35 * 20
x = 11.47
x = 11.5
answer
C. 11.5
--------------------
cos41 = x/11
x = 11 * cos41
x = 8.3
answer
A. 8.3
