82 less than r is less than -164
Oliga [24]

Answer:

82<r<-164

Step-by-step explanation:

We need to form an inequality of the given statement.

82 less than r is less than -164

Less than is written as <.

82 less than r means, 82<r

r is less than -164, r<-164

Combining two statements,

82<r<-164

Hence, the expression for 82 less than r is less than -164 is 82<r<-164.

helen has 30 tickets.Gina has 20 more tickets thank helen.what percent of tickets must Gina give helen so that both of them can
iren [92.7K]
Helen = 30 T (T = tickets)
Gina = 30 + 20 = 50 T

20% of 50 = 10

30 + 10 = 404
50 - 10 = 40

Gina must give 20% of her tickets for them to have equal amount of tickets.

Hope this helps!!

How do the expressions 72 divided and -72divided by (-9) and compare when they are evaluated?
padilas [110]

Complete question is;

How do the expressions 72 divided by 9 and -72 divided by (-9) compare when they are evaluated?

A. They have different values and are different signs.

B. They have different values but are the same sign.

C. They have the same value but are different signs.

D. They have the same value and the same sign

Answer:

D. They have the same value and the same sign

Step-by-step explanation:

For 72 divided by 9,it is;

72/9 = 8

Usually when we don't have any sign in front of a number, it is said to be positive.

Thus, the answer can be expressed as; +8

Also, when -72 is divided by (-9), it is;

-72/-9

The negative signs will cancel out to give; 8

Similar to the first division, since no sign is attached to 8,it is said to be positive as +8.

This means both divisions yield same values and same signs
