It’s really simple you can just type the equation into the calculator but it’s basically 8^3 which is 8 x 8 x 8 which is 512 and divide that by 2 which is 256 and add 9 which is 265.

Step-by-step explanation:

$9 + \frac{ {8}^{3} }{2} \\ 9 + \frac{8 \times 8 \times 8}{2} \\ 9 + \frac{512}{2} \\ 9 + 256 \\ 265$

What’s the least common multiple of the denominators of 9+3/4x=7/8x-10

Alona [7]

Answer:

x = 72

Step-by-step explanation:

$9 + \frac{3}{4} x = \frac{7}{8} x - 10 \\ \frac{3}{4}x - \frac{7}{8} x = - 10 - 9 \\ \frac{6}{8} x - \frac{7}{8} x = - 19 \\ - \frac{1}{8}x = - 19 \\ x = \frac{ - 9}{ - \frac{1}{8} } \\ x = 72$

Find and label -0 on the number line. Explain.<br><br> Does -0 just mean 0?

poizon [28]

The opposite of the number 0 that is -0 on the number line will be equal to 0 itself.

A number line may be defined as a scale consisting of numbers labelled from 0 to 9 which are used to plot or mark different points for various entities. Number line extends from 0 to 9 in the positive side that is usually taken as right-hand side and it extends from 0 to -9 in the negative side that is usually taken as the left-hand side. The numbers on the right-hand side of number line have their opposites on the left-hand side. The opposite of a number x is taken as -x. For example, the opposite of 4 is taken as -4 and 4 lies on right-hand side whereas -4 lies on left-hand side. 0 lies on the center of number line and is taken as the main point. It is neither positive nor negative so the opposite of 0 is 0. The figure of number line is attached.
