Expression
1
n minus 7
2
7 minus n
3
7 n
4
StartFraction n Over 7 EndFraction

Expression number:

the answer is 7 n

Step-by-step explanation:

Let

n> a number

we know that

The expression " the difference of 77 and a number n" is equivalent to say " Subtract a number n from 7"

therefore

the algebraic expression is equal to

7-n7−n

hes wrong its 2

Step-by-step explanation:

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
