The total cost c (in dollars) to participate in a ski club is given by the literal equation c=85x+60, where x is the number of ski trips you take.
a. solve the equation for x.
b. how many ski trips do you take if you spend a total of $315? $485?

a.

b. 3 and 5 ski trips

Step-by-step explanation:

Given function that shows the total cost for the x trips,

a. For solving the above equation for x,

We need to isolate x on the left side of the equation,

From equation (1)

b. If C = $ 315,

= 3,

If C = $ 485,

= 5

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
