If he needs at least 510 points and he has 375 points, then you would simply subtract. 510-375=135. Russell needs at least 135 points to get an A in Science.
Hope this helps!

Solve the equation and show all work please show steps!!<br> m/9 - 17=21
masya89 [10]
Okay. The question is m/9 - 17 = 21. First off, we will add 17 to both sides. -17 + 17 cancels out. 21 + 17 is 38. That leaves m/9 = 38. Multiply each side by 9 to isolate the m, because m is the numerator and 9 is the denominator. m/9 * 9/1 cancels out. 38 * 9 is 342. Let's check this. 342/9 is 38. 38 - 17 is 21. 21 = 21. There. x = 342.

The total surface area of a cube is 294cm^2.<br><br>Work out the volume of the cube.​
djverab [1.8K]

Answer:

343 cm ^3

Step-by-step explanation:

A cube has 6 squares of equal sizes. 294/6 = 49

The area of one square is 49

Since the area is the length squared, the square root of 49 is 7.

Volume of a cube is area times height. 49 x 7 = 343 cm^3

-3x + 2x = 10 + 12 + 2

-x = 24
