Answer: v = 5

Step-by-Step Solution:

=> -3(v + 4) = 2v - 37
= -3 * v - 3 * 4 = 2v - 37
= -3v - 12 = 2v - 37
= -3v - 2v = -37 + 12
= -5v = -25
= 5v = 25
=> v = 25/5 = 5

Therefore, v = 5

0.8% of what number is 6

algol [13]

0.8% of 75 is 6
convert 0.8% to decimal (0.08)
convert 0.08 to fraction (2/25)
x times 2/25 equals 6
multiply each side by the reciprocal of 2/25 (25/2)
2/25 times 25/2 equals one
6 times 25/2 equals 75
so x equals 75
