George has $15. He tries to buy a movie ticket ($9.00), a pretzel ($2.65), a drink ($1.35), and two veggie cups ($1.74 each) but
Ket [755]

Answer:

George doesn't have enough money because the total cost of what he wants to buy costs $16.48 and he has $15. This means he needs an extra $1.48 to be able to buy what he needs

Step-by-step explanation:

From the above question:

George has $15. He tries to buy a movie ticket ($9.00), a pretzel ($2.65), a drink ($1.35), and two veggie cups ($1.74 each) but he does not have enough money.

Look at the numerical expression George used: 15 −( 9 + 2.65 + 1.35 + 2(1.74) )

Use the order of operations to simplify this expression.

Using the order of operations we have:

=$ 15 - (9 + 2.65 + 1.35 + 2(1.74) )

= $15 -( 9 + 2.65 + 1.35 + 3.48 )

=$ 15 - (16.48)

= $-1.48

George doesn't have enough money because the total cost of what he wants to buy costs $16.48 and he has $15. This means he needs an extra $1.48 to be able to buy what he needs

PLEASE HELP ME QUICK what is the simplified form of x+9/x+1 + x-2/5?
Ira Lisetskai [31]

Answer:

A

Step-by-step explanation:

C and D are both wrong for the same reason. The denominator should be (x +1)*5 which means that either A or B is correct.

C and D have an error seldom seen on Brainly. It means that the denominator has been added rather than multiplied but even the addition is a little strange. Frankly, I don't know what has to be done to get either of them.

So the answer is

numerator: 5*(x + 9) +  (x + 1)(x - 2)

denominator: 5*(x + 1)

Simplify the numerator. Remove the brackets.

numerator: 5x + 45 + x^2 - 2x + x - 2               Gather like terms

numerator: x^2 + 5x - 2x + x + 43                      Simplify

numerator: x^2 + 4x + 43

Answer

x^2 + 4x + 43

==========

5(x + 1)

Julia used 1 foot square stone tiles to make a patio. She laid the tiles in a square, 7 tiles wide by 7 tiles long. What is the
marshall27 [118]

Answer: 49\ ft^2

Step-by-step explanation:

The formula that is used to calculate the area of a square is this one:

A=s^2

Where "s" is the side lenght of the square

You know that Julia used 1 foot square stone tiles, then each side lenght of the this tiles is:

s_{tile}=\sqrt{1\ ft^2}\\\\s_{tile}=1\ ft

Since Julia laid 7 tiles wide by 7 tiles long, the side lenght of the new patio is:

s_{patio}=7(1\ ft)\\\\s_{patio}=7\ ft

Therefore its area is:

A_{patio}=(7\ ft)^2\\\\A_{patio}=49\ ft^2
