We must follow order of operations rules (PEMDAS).

Thus, mult. and div. must be carried out before addn. and subtrn.

Calculate the quotient of (-2/5) and (4/5). In other words, divide (4/5) into (-2/5). Invert (4/5) and multiply:

(-2/5)(5/4) = -1/2

Then we have, in place of the original expression, the following expression:

-3/4 - 1/2 + (2 1/2).

Rewriting 2 1/2 as an improper fraction and elim. the parentheses yields:

-3/4 - 2/4 + 5/2, or -3/4 - 2/4 + 10/4, since the LCD is 4.

This yields 5/4 (answer)

How many deli sandwiches did she make?<br> Please help me.
SpyIntel [72]

Answer: 6 sandwiches

Step-by-step explanation:

To get the amount of roast beef that Marissa used you would have to subtract 2 3/4 from 5...which is 2.25 pounds of beef that she used.

Then you would divide 2.25 by 3/8 which is 6... meaning Marisa made 6 sandwiches!

WILL GIVE BRAINLIEST!!!!!!!!!!!

 A visual example of this is one my mother showed me. She drew a circle and laid out a piece of yarn around it so that it imitated the perfect shape of the circle. She laid out another piece that was as long as the circle's radius. She wrapped the longer piece around the shorter one, and I saw that it could wrap around it three times and still have at least 0.14 units left. I'm not sure if this helps, but the circumference of this circle is 18.84 cm ^2. I hope I answered your question.

What's the value of this python expression: (2**2) == 4?
vfiekz [6]

Answer:

Python will return:

True

Step-by-step explanation:

The math function ** is an exponent indicator.

The equation you made was:
2^2 =4

When you run this in python, it will return as true.

It is run as a Boolean expression because you have already provided the answer to the expression with the "==" statement.

If you had provided an incorrect answer (setting it equal to any number other than 4), it would return False.
