Please help me this is kinda hard​
yuradex [85]

All sides of a square/cube are the same. Since this is a cube, you'll find the volume by "cubing" (get it?) 4.4m.

4.4³ or 4.4 * 4.4 * 4.4 = 85.184m³ but you can round that to 85m³

I hope that helps!

Solve for x<br><br> 3(ax + 9) = -4 (-2 - 10x)
ivolga24 [154]

Answer:

19

-----   =   x

40-3a

Step-by-step explanation:

3(ax + 9) = -4 (-2 - 10x)

Distribute

3ax +27 = 8+40x

Subtract 3ax from each side

3ax-3ax +27 = 8+40x-3ax

27 = = 8+40x-3ax

Subtract 8 from each side

27-8 = 8-8+40x-3ax

19 = 40x-3ax

Factor an x on the right side

19 = x(40-3a)

Divide each side by 40-3a

19/(40-3a) = x(40-3a)/(40-3a)

19

-----   =   x

40-3a

Mitchell took a math exam today. If he got 63 out of 84 questions correct, what percentage did Mitchell get wrong? (answer using
Mars2501 [29]

Answer:

75%


Step-by-step explanation:

If Mitchell took a math exam and got 63 out of 84 questions correct, that would turn into the fraction: 63/84

In order to convert this to a decimal, you divide 84 by 63 (since every fraction is a division problem), and get 0.75.

When you change decimals into percents, you move the decimal point two times to the right. So, that would be 75.

Then you add the percent symbol and you're done!

I hope that helped :)

-5p - 3 = - 4

-5p = -4 +3
