Answer: The absolute value of 8

Step-by-step explanation:

Absolute value means how far away from 0 a number is.

If you have a number line, and the question is what is the absolute value of -10, for example, the answer would be ten, because it is 10 away from zero. if it was the absolute value of 10, however, it would still be ten, not -10.

3x-1/5-2/9x=124/5<br>how do you solve this?
Sergeu [11.5K]
So first you would combine the like-terms so you get:
\frac{7}{9} x - \frac{1}{5} = 124 \div 5
and combine the second like-terms:
\frac{7}{9}x - \frac{1}{5} = 24.8
now you only have a two step equation and you continue by doing the reciprocal and you add the -1/5 to the 24.8 where you get:

7/9x=24.6

then because the 7/9 is being multiplied by the x and your trying to isolate it you divide it by the 7/9 on both sides and you'll end up getting

x=31.628571429....

Two​ trains, Train A and Train​ B, weigh a total of 489 tons. Train A is heavier than Train B. The difference of their weights i
makvit [3.9K]

Answer:

Weight of Train A = 454 tons

Weight of Train B = 35 tons

Step-by-step explanation:

It is given that:

Let,

A represent weight of Train A

B represent weight of Train B

According to given information:

A + B = 489      Eqn 1

A - B = 419       Eqn 2

Adding Eqn 1 and 2

A + B + A - B = 489 + 419

2A = 908

Dividing both sides by 2

\frac{2A}{2}=\frac{908}{2}\\A = 454

Putting A = 454 in Eqn 1

454 + B = 489

B = 489 - 454

B = 35

Therefore,

Weight of Train A = 454 tons

Weight of Train B = 35 tons
