Consider this system of equations: (Look at screenshot to better understand how to answer the question.)

(equation A)

(equation B)

The expressions that give the value of y are 1. A - 3B 2. A - (3B/2) 3. 2A - 3B 4. (A/3) + B and 1. A + 3B 2. A + (3B/2) 3. (A/3) - B 4. (A/3) - 2B.

The solution for the given system is 1. (27/13, 60/13), 2. (-27/13, 60/13) 3. (27/13, -60/13), 4. (-27/13, -60/13).

Expressions for y:

1. A - 3B

3. A/3 - B

3. (27/13, -60/13)

Step-by-step explanation:

Expressions for y:

A - 3B

A/3 - B

Find combinations to eliminate x

A) 8x + y = 12

B) 2x - 3y = 18

Expressions for y:

A - 3B

A/3 - B

y = 12 - 8x

2x - 3(12 - 8x) = 18

2x + 24x - 36 = 18

26x = 54

x = 54/26 = 27/13

y = 12 - 8(27/13) = -60/13

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
