i really help with this problem

Question

Define a variable and write each phrase as an algebraic expression.

> $5 dollar less on dinner than James spent

> 3 more than twice as many ringtones as Mary

 

Answer 1

> $5 dollar less on dinner than James spent

> 3 more than twice as many ringtones as Mary

Are these expressions including a "greater than" sign,

or were you merely using the > to designate a place marker?

 

If the expressions are including greater than then:

 

 "greater than $5 less on dinner than James spent"

Let D = amount you are looking to spend

Let J = amount James spent

D > J - 5

 

"greater than 3 more than twice as many ringtones as Mary"

Let R = number of ringtones you are looking for

Let M = number of Mary's ringtones

 

R > 2M + 3

Answer 2

Let x be the amount james spent for dinner

Then x - 5 would be the answer to your first problem

 

Let R be the number of ring tones M had

Then 2R + 3

Would be the second expression
