A pair of pants costs twice as much as a shirt. The total cost of 1 pair of pants and 1 shirt is $18. If s represents the cost of 1 shirt, which equation could you use to find the cost of 1 shirt?
A:s/2=18
B:s plus s=18
C:2s=18
D:2s plus s= 18

See the explanation. :)

Step-by-step explanation:

As a side note, while I know you don't need to solve the problem and just need the equation, I'm going to solve it anyway so you can see how problems like this work so that you can solve them for yourself. :)

As the problem states, the cost of a single shirt (s) and a single pair of pants (p) TOGETHER is $18. It also states that a pair of pants (p) costs twice as much as a shirt (s). This, believe it or not, gives us all the information we need to solve the problem.

Pretty quickly, we can come up with two equations:

2s = p

p + s = 18

Then, through substitution, we find that:

2s + s = 18

Now, that right there is your answer, and you can just stop here to keep going if you'd like. I, however, am going to solve the problem and find the numbers. I implore you to continue reading.

Continuing on:

3s = 18

3s / 3 = 18 / 3

s = 6

Finally, we return to our original two equations to figure out the following:

2(6) = p

12 = p

Finally, we find that s = 6 and p = 12.

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.

answer: group b.
