Assuming 2x2 is 2 multiplied by 2, and not a variable..

1. Multiply 2 and 2.

4 - 2x +7

2. Add 7 to 4.

11 - 2x.

Since the answer can no longer be simplified, 11 - 2x is your final answer.

Answer:

19) ( $\frac{-2}{5}$ )^2 = $\frac{4}{25}$

20) - $9^{2}$ = -81

21) $2^{4}$ = 16

Step-by-step explanation:

The only wrong ones are

19) ( $\frac{-2}{5}$ )^2 = $\frac{4}{25}$

20) - $9^{2}$ = -81 ... negative is not inside a parenthesis that's why it is still negative

21) you can add another way is $2^{4}$ = 16

Everything else looks good. Great job!

ms anderson bought 45 baseball hats. Mets hats cost $18 and Yankee hats cost $24. If she spent $1050, how many of each did she b

DerKrebs [107]

First, you have to set up two equations. X + y = 45 18x + 24y = 1,050 To do this, you have to solve for an exponent by cancelling out the other one. To solve for y, you multiply everything in the first equation by -18. -18x -18y = -810 This cancels out the x and leaves you with 6y = 240. Divide both sides by 6 and you have the number of Yankee hats that were bought. Then, you have to substitute 40 for y in the first equation and solve for x.
