The Oakville High School Marching Band sold gift wrap to earn money for a band trip. Solid color gift wrap sells for $3.50 per roll and printed gift wrap sells for $5 per roll. The band needs to earn $2,500 for an upcoming competition. If the band sells 325 rolls of printed paper, write and solve a linear equation to find the number of sold paper they must sell

Let, number of solid color gift sold is x and printed gift wrap is y.

Also, number of printed paper sold , 325.

Expressing, it in mathematical equation :

y = 325     1)

Also, The band needs to earn $2,500 for an upcoming competition.

So ,

3.5x + 5y = 2500     2)

Solving equation 1 and 2 :

3.5x + 5(325) = 2500

3.5x = 2500 - 1625

3.5x = 875

x = 250

Therefore, number of solid paper they must sell is 250.

Hence, this is the required solution.

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.
