The cost of paper varies directly with the number of reams bought. suppose 2 reams cost $5.10. write a linear equation that could be used to find the cost of x reams of paper. find the cost of 15 reams of paper

let x be the number of reams of paper and $y be the cost.

y=kx

when x=2, y=5.10,

5.10=k(2)

2k=5.10

k=2.55

y=2.55x

cost of 15 reams of paoer= 2.55(15)= 38.25

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
