A group of 10 students went to a football game at their university. They each bought a ticket for $x and spent $20 on a t-shirt. A group of 4 adults went to the same football game and paid five times as much for each of their tickets as each student. The group of adults also bought a long-sleeved t-shirt for $25 each. The group of students spent the same amount as the group of adults. What is the cost of each student ticket? Write and solve an equation to model the problem.

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

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

yes

step-by-step explanation:

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
