Answer:
15/21 and 14/21 so 5/7 is greater
Step-by-step explanation:
21 is the least common multiple for 3 and 7 so you multiply 7 by 3 to get 21 and do the same with the numerator to get 15 and vice versa.
Answer:
12 3/5
Step-by-step explanation:
Well the absolute value of something means that it could have possibly been a negative answer. so |x-3| = 14 could be
x - 3 = 14
or
x - 3 = - 14 (this is usually written -(x-3) = 14)
so we solve both of these
x - 3 = 14
x = 17
and
x - 3 = -14
x = -11
to shiw its the same i will do other way
-(x - 3) = 14
-x + 3 = 14
-x = 11
x = - 11
Answer:
27, 80, 20
Step-by-step explanation:
Let t represent the third number. The second number is 4 times that, 4t. The first number is 7 more than the third, so is (t+7). The sum of the three numbers is ...
(t+7) + 4t + t = 127
6t +7 = 127 . . . . . . collect terms
6t = 120 . . . . . . . . .subtract 7
t = 20 . . . . . . . . . . . divide by 6; the 3rd number is 20
4t = 80 . . . . the second number is 80
t+7 = 27 . . . the first number is 27
The three numbers are 27, 80, and 20.
