Rami sold concessions during a concert. he sold bottled water for $3.50 each and bags of trail mix for $4 each. by the end of the evening, rami sold 400 items for a total of $1,475. how many bottles of water and how many bags of trail mix did rami sell? 125 bottles and 275 bags of trail mix 150 bottles and 250 bags of trail mix 250 bottles and 150 bags of trail mix 275 bottles and 125 bags of trail mix

250 bottles and 150 bags of trail mix

Step-by-step explanation:

X + y = 400

3.50X + 4y = 1475

x = 400-y

3.50(400-y) + 4y = 1475

1400 - 3.50y + 4y = 1475

1400 +0.50y = 1475

0.50y = 75

y = 75/0.5 = 150

x = 400 - 150 = 250

250 bottles and 150 bags of trail mix

f

step-by-step explanation:

f

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
