Answer:

5) 9

6) 15

7) 16

Step-by-step explanation:

5) 17.25 - (4.5 + 3.75)

Parenthesis comes first

4.5 + 3.75 = 8.25

17.25 - 8.25 = <u>9</u>


6) (14 - 7) + (3 + 5)

7 + (3 + 5)

7 + 8 = <u>15</u>


7) 4 ÷ 2 × 8

2 × 8 = <u>16</u>

Solve the system of linear equations by adding or subtracting. Show all work!
Thepotemich [5.8K]

Answer:

x = -2, y = -2

Step-by-step explanation:

Your goal is to try and cancel out a variable. I want to get rid of y so i subtracted the first equation from the second one.

After that I solve for x and got x=-2.

I used x=-2 and plugged it back into either of the equation to solve for y.

Pie

Answer:

B (√6)/4

Step-by-step explanation:

The smallest multiplier that will make the denominator of the fraction into a perfect square is 2, so you have ...

\displaystyle\sqrt{\frac{3}{8}}=\sqrt{\frac{3\cdot 2}{8\cdot 2}}\\\\=\sqrt{\frac{6}{16}}=\frac{\sqrt{6}}{\sqrt{16}}\\\\=\frac{\sqrt{6}}{4}

_____

Answer choice D is also a correct rationalization of the denominator, but is not simplified as far as it can be. √24 = 2√6, so a factor of 2 can be cancelled from numerator and denominator, giving answer choice B.
