1. A local band is selling hats (x), shirts (y), and jackets (z) at their show. One fan bought 5 hats, 1 shirt, and 2
jackets for a total cost of $277.92. A second fan bought 1 hat, and 1 shirt for $41.98, while another fan bought 3
hats, 4 shirts, and 1 jacket for $237.92. Which of the following systems represents the given information?
A 5x - y - 2z = 277.92

C 5x + y + 2z = 277.92
x-z= 41.98
x + y = 41.98
3x – 4y - z = 237.92
3x + 4y +z = 237.92

B 5x + y + 2z = 277.92
x + y + z = 41.98
3x + 4y + z = 237.92

D 5x + y + 2z = 41.98
x + y +z = 237.92
3x + 4y + z = 277.92

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

use formula for the circle a=3.14

step-by-step explanation:

the correct answers i think are b. and d.

give me brainliest if it is correct!

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
