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.
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
For this one your answer is -309
Answer:
25y + 15x - 0.2y - 6 +(-2) =31.8
Answer:
-24
Step-by-step explanation:
-3 (x + 4) - 2 = -2 (x - 5)
-3x - 12 - 2 = -2x + 10
-3x + 2x = 10 + 12 + 2
-x = 24
x = -24
