Which of the following equations are equivalent to -2m - 5m - 8 = 3 + (-7) + m?
NARA [144]

Answer:

B) -7m - 8 = m - 4

D) m - 4 = -7m - 8

E) -8 - 7m = -4 + m

Step-by-step explanation:

Solve all of the equations to see if they end up with the same result. Start with the original:

-2m - 5m - 8 = 3 + (-7) + m

-7m - 8 = -4 + m (now we know B and D and E are correct)

-7m - m - 8 = -4 + m - m

-8m - 8 = -4

-8m - 8 + 8= -4 + 8

-8m = 4

In the magic square shown, the sums of the numbers in each row, column and diagonal are the same. What are the values of x, y, z
garri49 [273]
v=23, w=19, x=22, y=26, z=20;; to find the answer, set the expressions equal to each other, since the sum of the numbers should be the same.

Use v+w+24=v+43 and solve for w, which would result in w=19.

You can also use x+z+24=z+46 to find x– or x=22.

Plug in the values for x and w, and find y using 25+22+19=y+40 or 66=y+40 and results in y=26.

After plugging in the y value, you can easily find v and z.

v+18+25=66– since 66 is the sum of a full row, and the sums of the numbers in each row, column, and diagonal are the same, so therefore, v+43 should also equal 66. This results in v=23, and, using the same value for the sum of z+21+25, or z+46=66, we find that z=20.

The final answer is v=23, w=19, x=22, y=26, z=20.

Sorry it took so long;; I hope this helps :)
