Step-by-step explanation:

defining variables:

since you are trying to find t shirt cost and jeans cost, your variables would be

the cost of the t shirt and the cost of jeans, denoted by any variable you want.

I'll use x and y since they are the most common variables (x = shirt y = jeans)

Equation

4 shirts + 5 jeans = 160 dollars

4x + 5y = 160 (the cost of 4 shirts + the cost of 5 jeans is $160)

the cost of 2 shirts + 6 jeans = $150

2x + 6y = 150

Selena: 4t +5j = 160

Taylor: 2t + 6j = 150

t= t-shirts

j = jeans

Step-by-step explanation:

8t + 10j = 320

-8t -24j= -600

-14j = -280

j = $20 each pair of jeans

4t + 5(20) = 160

4t + 100 = 160

4t = 60

t = $15 each t-shirt

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
