Which algebraic expression is a difference with two terms

The algebraic expression which is a difference of two terms is:

                   B.    5y-7

We know that any algebraic expression is a difference of two terms if there are two terms in an expression which are separated by a subtraction sign.

A)

              3y+1

In this expression we have two terms 3y and 1 which are separated by a addition sign.

Hence, option: A is incorrect.

B)

              5y-7

In this expression we have two terms as 5y and 7 which are separated by a negative sign or a subtraction sign.

                         Hence, option: B is correct.

C)

                -2y+5+3

In this expression we have three terms  "2y", "5" and "3"

Hence, this option is incorrect.

D)

             5(y-6)

Here we have two terms 5 and (y-6) which are separated by a multiplication sign.

Hence, option: D is incorrect.

50-38=12

step-by-step explanation:

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
