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?​

Answers

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

A nonstop flight from Albuquerque, NM to Atlanta, GA takes 3 hours. If the plane flies a total of 1,269 miles, what is the plane’s unit rate in miles per hour?
A. 3,807 mph
B. 1,266 mph
C. 432 mph
D. 423 mph

Answers

Answer:

423 mph

Step-by-step explanation:

To find the answer, you have to divide 1,269 by 3 since we want to find how many miles the plane travels in one hour. Doing this, we end up with 423 which is the answer.

Answer: D. 423 mph

Step-by-step explanation:

A nonstop flight from Albuquerque, NM to Atlanta, GA takes 3 hours. If the plane flies a total of 1,269 miles, what is the plane’s unit rate in miles per hour?

1,269 % 3 = 423

Solve 5x+3=3x+11

Please can someone answer this.​

Answers

5x + 3 = 3x + 11

• first put all the x-values on one side and the rest on the other

Remember: when the number moves to the other side of the equal sign the sign (+ OR - switches. For ex: the 3 on the left becomes negative when moved to the right side of the equal sign)

5x - 3x = 11 - 3

• subtract left and right sides separately

2x = 8

• divide both sides by 2 to solve for x

2x/2 = 8/2

x = 4 (final answer)

5x+3=3x+11
2x+3=11
2x= 8

A sequence is defined by the term-to-term rule

Given that u, = 1,
a) find u,
b) find uz
c) find us

Answers

Answer:

see solution below

Step-by-step explanation:

Correct question

A sequence is defined by the term-to-term rule

Un+1 = u. + 3

Given that u1 = 1,

a) find u2

b) find u3

c) find u5

a) Given the recursive formula;

Un+1 = un + 3

When n = 1;

U1+1 = U1 + 3

U2 = U1 + 3

U2 = 1 + 3

U2 = 4

b) U3 = U2 + 3

U3 = 4 + 3

U3 =7

c) U4 = U3 + 3

U4 = 7+3

U4 = 10

U5 = U4 + 3

U5 = 10 + 3

U5 = 13

Mom buys a rectangular rug with an area of 7 1/6 square meters. The length of the rug is 3 1/3 meters. What is the width of the rug?

Answers

Answer:

Step-by-step explanation:

Multiply the length by 2 so, 3 1/3 x 2 then subtract that answer from the area, and you have the width

The width of the rectangle given the area and length of the rectangular rug is 4 3/10 meters

Given:

Area of the rug = 7 1/6 square meters

Length of the rug = 3 1/3 meters

Area of a rectangle = Length × width

7 1/6 = 3 1/3 × w

43/6 = 10/3w

w = 43/6 ÷ 10/3

w = 43/6 × 3/10

w = (43 × 3) / (6 × 10)

w = 129/30

w = 4 9/30

= 4 3/10 meters

Therefore, the width of the rug is 4 3/10 meters

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
