Walnuts, peanuts, and chocolate chips are mixed composed in a ratio of 7: 2: 5. what is the weight of the mixture if 2.5 lbs of chocolate chips were used for making it?

show your work!

The weight of the mixture is equal to

Step-by-step explanation:

Let

x-----> the weight of walnuts

y----> the weight of peanuts

z----> the weight of chocolate chips

we know that

-----> equation A

-----> equation B

-----> equation C

Step 1

Substitute the value of z in the equation B and solve for x

Step 2

Substitute the value of z in the equation C and solve for y

Step 3

Find the weight of the mixture

we know that

The weight of the mixture is equal to

substitute

∠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.
