Ok so, adam had 91 dollars. if he spent 21 dollars on new books, what is the ratio of money he still has, to money he's spent. the answer is 10: 3, but i need a show your work example from somebody! !

Step-by-step explanation:

Let

x ----> the money Adam still has

y ---> the money Adam spent

r ---> the ratio of money he still has, to money he's spent.

we know that

The money Adam still has is the same as the money he originally had minus the money he spent.

so

we have

Find the ratio

Simplify

Divide by 7 both numerator and denominator

∠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.

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
