Answer:

B

Step-by-step explanation:

solving the inequality

9 - y > 12 ( subtract 9 from both sides )

- y > 3 ( multiply both sides by - 1 )

Remembering to reverse the inequality symbol when multiplying/ dividing by a negative quantity

y < - 3 ← reverse symbol

Thus y is less than or equal to - 3

The only value from the list which makes this true is - 6 → B

What is the volume of the composite figure below? (formula for volume of a prism is 1/3 Bh where B is the area of the base.)
arsen [322]

Answer:

Last Option; 84 cu. mm

Step-by-step explanation:

We know that;

Volume = 1/3(Bh)

And that this is figure has a square base, therefore B that represents the area of the base will be: 6 * 6 = 36

And height = 7mm

Therefore we can say;

Volume = (1/3)*(6 x 6)*(7)

Volume = (1/3)*(36)*(7)

Volume = (12)*(7)

<u>Volume = 84</u>

Hope this helps!

Solve, using the correct order of<br> operations, when x = 7 and y = 3<br> (x – 3) + 2y
sweet [91]

Answer:

10

Step-by-step explanation:

<em>Since it given that:</em>

<em>x = 7 and y = 3</em>

<em>We can substitute x and y:</em>

<em>(7-3) + 2(3)</em>

<em>7 - 3 = 4</em>

<em>4 + 2(3)</em>

<em>2(3) = 6</em>

<em>4 + 6 =10</em>

<em>Thus the answer is 10.</em>
