From stations A and B, the distance between which is 910 mi,
two trains left simultaneously moving towards each other. The
speed of one train was 10 mph greater than the speed of the
other one. In 5 hours the trains met. Find the speed of each train.
Answers
Answer:
The slowest train goes at 86 mph and the fastest train goes at 96 mph.
Step-by-step explanation:
Distance and Speed
Assume x is the speed of the slowest train, therefore the speed of the fastest train is x+10.
The distance is calculated as:
d = vt
Where v is the speed and t is the time.
The distance traveled by each train in 5 hours is:
Slowest: 5x
Fastest: 5(x+10)
The sum of both distances is 910 miles:
5x + 5(x + 10) = 910
Operating:
5x + 5x + 50 = 910
10x = 910 - 50 = 860
x = 860/10
x = 86
The slowest train goes at 86 mph and the fastest train goes at 96 mph.

The values of m and n are whole numbers greater than 1. Which is true about the quotient
Answers
Answer:
"The expression will always equal m" is true about the quotient of [tex]\frac{m}{n}[/tex] ÷ [tex]\frac{1}{n}[/tex]
Step-by-step explanation:
Let us solve the question
∵ The expression is [tex]\frac{m}{n}[/tex] ÷ [tex]\frac{1}{n}[/tex]
→ In the division of fractions, we change the division to multiplication
and reciprocal the fraction after the division sign
∵ The reciprocal of [tex]\frac{1}{n}[/tex] is [tex]\frac{n}{1}[/tex]
∴ [tex]\frac{m}{n}[/tex] ÷ [tex]\frac{1}{n}[/tex] = [tex]\frac{m}{n}[/tex] × [tex]\frac{n}{1}[/tex]
→ In the multiplication of fractions, we can simplify the terms in
the numerators by the terms in the denominators
∵ There is n in the numerator and denominator
∴ Cancel n up and down
∴ [tex]\frac{m}{n}[/tex] × [tex]\frac{n}{1}[/tex] = [tex]\frac{m}{1}[/tex]
∴ [tex]\frac{m}{n}[/tex] × [tex]\frac{n}{1}[/tex] = m
∴ [tex]\frac{m}{n}[/tex] ÷ [tex]\frac{1}{n}[/tex] = m
∴ The quotient is m
∴ The expression will always equal m

Answers
Answer:
a)
(i) 43, 56
(ii) -1,3
b)-27
c) -21 +4n
Step-by-step explanation:
For a,i, you can see that it decreses by 7 each time so you subtract 7 from 50 to get 43, then you subtract 7 from that to get 56. For a,ii it increases by 4 each time so you add 4 to -5 to get -1, then add 4 to that to get 3. For b, because it is the 15th term you are looking for, you can plug 15 into the equation as n so 78-7n to 78- 7*15, 78-105, -27. For c, you know that each time it increases by 4, so you know you add 4n, and then for the base, you have to find the term before -17 so you subtract 4 to get -21. Put it together and get -21+4n.

32.3=80
Step-by-step explanation:
Amount of money saved : spent = 2 : 3.
Since amount of money saved = £32,
Amount of money spent = £32 * (3/2) = £48.
Total amount of money = £32 + £48 = £80.
Therefore I received £80 for my birthday.

Answers
Answer:
x = 13.6
Step-by-step explanation:
Here, we want to find the value of x
to find the value of x. we are going to use the sine rule
It states that the ratio of the sine of an angle to the measure of the side facing the angle is fixed for a triangle
In this case;
11/ sin 27 = x/ sin 34
x = 11 sin 34/sin 27
x = 13.6

select all the expressions equivalent to 5x + 6x + 3x : 11x + 3x, 14x + x, 2 (3x + 4x), 3x(2 + 1) + 5x, 5x + 3(2x + x)
Answers
Step-by-step explanation:
5x + 6x + 3x
= 14x.
Now we compare the expressions with the result:
11x + 3x = 14x. (correct)
14x + x = 15x. (incorrect)
2(3x + 4x) = 2(7x) = 14x. (correct)
3x(2 + 1) + 5x = 3x(3) + 5x = 9x + 5x = 14x. (correct)
5x + 3(2x + x) = 5x + 3(3x) = 5x + 9x = 14x. (correct)
Hence our answers are the 1st, 3rd, 4th and 5th.
If x²-2=2⅔ +2-⅔

Answers
Answer:
Step-by-step explanation:
x²-2=2⅔ +2-⅔
x^2 = 2^1 + 2⅔ +2-⅔
x^2 = 4.21736
x = 2.0536.
Plug this into 2x^3 - 6x:
= 2(2.0536)^3 - 6(2.0536)
= 5
So 2x^3 - 6x = 5.
