An express train travelled at a certain average speed from Town X to Town Y which was
150 km away. It then continued its journey to Town Z at an average speed 20 km/h faster than
its initial average speed. Town Ywas 200 km from Town Z. If it took the same time to travel for
both parts of the journey, what was the train's average speed for the first part of the journey?
Answer:
60 km/hr
Step-by-step explanation:
Let the speed at the initial average speed from Town X to Town Y be a.
We are told that it journeyed to Town Z at an average speed 20 km/h faster than its initial average speed. Thus, its average speed here is (a + 20) km/hr.
Town Y was 200 km from Town Z.
Thus, time spent here is;
t_2 = 200/(a + 20)
Time from X to Y is; t_1 = 150/a
We are told that it took the same time to travel for both parts of the journey.
Thus; t_1 = t_2
150/a = 200/(a + 20)
Cross multiply to get;
150(a + 20) = 200a
150a + 3000 = 200a
200a - 150a = 3000
50a = 3000
a = 3000/50
a = 60 km/hr
Need answer simplify -2/5+4/3=
Answer:
The answer should be 14/15.
Step-by-step explanation:
The answer is 14/15 because -2/5 and 4/3 with a common denominator turns into -6/15 and 20/15.
Then you add both of them together.
-6/15 + 20/15 = 14/15

Which expression is equivalent to 12(4m−2n+4)?
1.2m−n+2
2.2m−2n+4
3.8m−4n+4
4.8m−4n+8
Answer:
1. 2m - n + 2
Step-by-step explanation:
12×4m - 12×2n + 12×4. ( because 12 is multipled by whole bracket)
48m - 24n + 48.
2m - n + 2. (by finding common factor 24)

the answer is $300
Step-by-step explanation: when increasing by 100% it is the same as multiplying by 2
Plot the points (-3, 4)(−3,4)left parenthesis, minus, 3, comma, 4, right parenthesis and (4, 4)(4,4)left parenthesis, 4, comma, 4, right parenthesis on the coordinate plane below
Answer:
The image shows the points on a coordinate axis.
Step-by-step explanation:
The first point is [tex](-3,4)[/tex].
This means that the point on the [tex]x[/tex] axis is [tex]-3[/tex] and [tex]y[/tex] axis is [tex]4[/tex]. The point is in the second quadrant.
The second point is [tex](4,4)[/tex].
This means that the point on the [tex]x[/tex] axis is [tex]4[/tex] and [tex]y[/tex] axis is [tex]4[/tex]. The point is in the first quadrant.
The image shows the points on a coordinate axis.

Isaac walks 6/10 of a mile of a mile in 1/5 of an hour. If Isaac’s walking rate remains constant, what is Isaacs walking rate in miles per hour?
Answer:
3 miles per hour.
Step-by-step explanation:
To get his walking rate in miles per hour, we multiply 1/5 by its reciprocal, 5/1. We also multiply 6/10 by 5/1. This gets us 30/10 of a mile in an hour. We can simplify 30/10 to 3. This means he walks at 3 miles per hour.

The ratio of men to women at a class is 6 to 5. How many women students are there if there are 3,600 men?
Answer:
3,000 women
Step-by-step explanation:
6 : 5
m w
so if 6 represents men and 5 represents women, then
3,600/6=600
so
5x600=3,000
so your answer would be 3,000
Tshirt costs 69.9$ 15% off 6.25 tax deduct how much t shirt cost step by step explanation
the _________ is a number that is multiplied. the number that indicates how many times this number is used as a factor is the ___________
The base is a number that is multiplied. The number that indicates how many times this number is used as a factor is the exponent
For example, the number 2^3 expands out to 2*2*2. We have three copies of the base '2' being multiplied.
Another example: 5^2 = 5*5.
Answer:
The "Factor" is a number that is multiplied. The number that indicates how many times this number is used as a factor is the "Exponent".
Step-by-step explanation:
Example: 7 • 7 can be written as 72, 7 is the base and 2 is the exponent. The exponent 2 means there are two factors.

3 There are 8 teams in the
recreational soccer league. Each
team is comprised of 9 fourth-
grade students and 5 fifth-grade
students. Which expression could
be used to find the total number of
students in the soccer league?
A. (8 + 9) * 5 =
B. (8 x 9) + 5 =
C. 8 + (9x5) =
D. 8 (9 + 5) =
Answer:
On each team there is the same number of teammates, the answer is D. 8 (9 + 5).
Step-by-step explanation:
If you add up the amount of teammates then multiply that by the number of teams.
Therefore, D. 8 (9 + 5) is the answer.

d. The opposite of - 10t and t - 10t
Answer:
The answer is t.
Step-by-step explanation:
We need to find the sum of opposite of - 10t and t - 10t.
Opposite of -10t = 10 t
So,
10t + (t-10t)
Grouping the numbers,
(10t+(-10t)) + t
= 0 + t
= t
Hence, the answer is t.

The scale factor from the large triangle to the small triangle is 3:1 What is the length of side x of the smaller triangle?
Answer:
10 i guess
cause
8*3=24
3*10=30
Step-by-step explanation:
Since the scale factor of the large to small triangle is 3 : 1, the side lengths of the small triangle are 1/3 of the big triangle side lengths. (such as 8 compared to 24)
Therefore 3x = 30 and x = 10.
the chess club accepts 5 new members each week and it had 37 members after 6 weeks ? how many members per week and how many members did it start off with
Answer:
it started off with 7 members
(read the whole explanation)
Step-by-step explanation:
Question: the chess club accepts 5 new members each week and it had 37 members after 6 weeks ? how many members per week and how many members did it start off with.
If the chess club accepts 5 each week and they had 6 members after 6 weeks you should multiply 5x6=30. We don't know when the chess club started.. it could be 6 or 7 weeks ago and I'm pretty sure we all know that 7x5=35. but it only says 6 weeks ago so the answer is 7,

Answer:
20cm squared
Step-by-step explanation:
so the scale factor is 1:2 so you just double the area so,
10cm squared x 2 = 20cm squared
Answer:
D: 40
Step-by-step explanation:
If the scale factor is 1:2 it means that each side is twice as big after being scaled. However, because the area is width * height that means that the area of the scaled one gets doubled two times, so is actually 4x bigger. This means the answer is 4 * 10 = 40 square cm

how do i solve -3x + 2y = -4
Answer:
y= 3/2 x -2
Step-by-step explanation:
I guess you want to find the y=mx+b form
So you do +3x on both sides which will gave you: 2y= 3x-4
Then, you will divide by two on both sides to find the y value: 2y/2 = (3x-4)/ 2
So 3/2 is the fraction like the answer above and -4/2 = -2
Hope that helps :)
