The number is 28.
The equation would be:
237 + 6(x) = 405
The problem states that 6 times the opposite of a number, however, since the number sign was not given, we do not know whether it is in a positive or negative form. So we leave it as only x.
237 + 6x = 405
6x = 405 - 237
6x = 168
6x / 6 = 168 / 6
x = 28
To check:
237 + 6 (28) = 405
237 + 168 = 405
405 = 405

Answer:
Maria is 66" tall, Juan is 51" tall
Step-by-step explanation:
There are 12 inches to a foot.
Luis is 62" tall
Maria is 1/3 of a foot taller than Luis, 1/3 of 12 is 4, (multiply 12 by 1/3)
So Maria is 4 inches taller than Luis, making her 66" tall
Juan is 1 1/4 feet shorter than Maria, that's one foot and 1/4 of a foot shorter, 1/4 of 12 is 3 (multiply 12 by 1/4)
So Juan is one foot (12 inches) plus 3 more inches shorter than Maria,
Juan is 15 inches shorter than Maria, making him 51" tall
