Anumber has three digits. the number is less than 140.the number has 7 as a factor. the number is even. the sum of the digits is less than 9. what’s my number?

Step-by-step explanation:

Tough one!

Divisible by 7 and even...meaning it must be divisible by 14.

14 * x where x is less than 10 is the answer :)

That's the only thing I can figure out :)

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
