Answer:
We simplify the equation to the form, which is simple to understand
5x+25=10
We move all terms containing x to the left and all other terms to the right.
+5x=+10-25
We simplify left and right side of the equation.
+5x=-15
or this is another way
Simplifying
5x = 25 + -10
Combine like terms: 25 + -10 = 15
5x = 15
Solving
5x = 15
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '5'.
x = 3
Simplifying
x = 3
We divide both sides of the equation by 5 to get x.
x=-3
Answer:
5. The answer is 2
6. Her error is that she was supposed to subtract 16 minus 12 instead of 12 minus 2.
Step-by-step explanation:
For number 5 all I did was solve.
12 + (25 - 5^2) - 2 =
12 + 0 - 2 =
12 - 2 = 10
10 ÷ 5 = 2
So, for number 5 the answer is 2.
For number 6, you should know that when there are only plus and minus signs you solve from left to right.
She instead put parentheses where there shouldn't of been, and because of that she is wrong.
Hope this helps! :)

Answer:
896 metres per minute
Step-by-step explanation:
not for much sure
It would take 4 hours for both trains to meet.
Speed is the ratio of distance travelled to time taken. It is given by:
Speed = distance / time
Let t represent the time at which both trains meet, and d represent the distance covered by train A, hence:
For train A:
100 = d / t
t = d/100
For train B:
200 = (1200 - d) / t
t = (1200 - d) / 200
d/100 = (1200 - d)/200
2d = 1200 - d
3d = 1200
d = 400 km
t = 400 / 100 = 4 hours
It would take 4 hours for both trains to meet.
