LOTS OF POINTS, PLEASE ANSWER

Train A and train B leave a central station at the same time. They travel the same speed, but in opposite directions, with train A heading towards station A, and train B heading towards station B. Train A reaches station A after 4 h. Train B reaches station B after 3 1/2 h. Station A and Station B are 562.5 mi apart.

What are the rates of the trains?

Answers

Answer 1

Answer:

since the rate is the same for both trains, and we know that the distance train A travels plus the distance train B travels equals 562.5 miles, we can use the D(istance) = R(ate) * T(ime) formula to solve this.

Train A:

da = R * 4

Train B:

db = R * 3.5 (using 3.5 instead of 3 and 1/2)

Solve for R:

R * 4 + R * 3.5 = 562.5

7.5 * R = 562.5

R = 75

The trains are traveling at 75 miles per hour.

Step-by-step explanation:

Answer 2

Answer:

speed = distance / time

since they are moving in opposite direction, the time is the sum of the two times = 2 1/2 + 4 = 6 1/2 = 13/2

speed = 585/(13/2) = 90 miles per hour.

Step-by-step explanation:

I hope it helps.

John bow 27 packets of paper plates, costing £52.65, for a dinner party that he was hosting. his wife reminded him that he should have bought 35 packets to cater everyone who was coming. how much would this have cost?

Answers

You would divide £52.65 by 27 to find out what 1 packet costs, thus leads us to £1.95. Then you would do £1.95 x 35 as there are 35 packets to get the answer £68.25

Solve 2( 4x - 1) = 18

Answers

the answer is 2.5

2 (4x - 1) = 18
8x - 2 = 18
8x = 20
x = 2.5

Answer:

x=2

Step-by-step explanation:

Simplifying

2(4x + 1) = 18

Reorder the terms:

2(1 + 4x) = 18

(1 * 2 + 4x * 2) = 18

(2 + 8x) = 18

Solving

2 + 8x = 18

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2' to each side of the equation.

2 + -2 + 8x = 18 + -2

Combine like terms: 2 + -2 = 0

0 + 8x = 18 + -2

8x = 18 + -2

Combine like terms: 18 + -2 = 16

8x = 16

Divide each side by '8'.

x = 2

Simplifying

x = 2

Roy and two friends are at a game center. Each person buys hot dogs for $3, fries for $2.49, and a drink for $2.50. They also have a coupon for $1 off each drink. Write an expression to represent the total cost. Then find the total cost.

Answers

Answer:

$20.97

Step-by-step explanation:

3 people, meaning to multiply each one by 3.

Total price of Hot Dogs= 9.00

Total price of Fries=7.47

Total price of Drinks=7.50

7.50 - 3= $4.50

9.00+7.47+4.50= $20.97

help me plzzzz asap Kendra is buying an outfit that is on sale for 20% off. The original price of the outfit is $109. What is the sale price?

$130.80

$87.20

$21.80

$78.20

Answers

answer: 87.20
explanation: 20 percent is equal to 0.2 so then you multiply 0.2 by $109 which gives you $21.80 so you then subtract $21.80 from $109 and you get $87.20 as your final answer.

Answer:

The answer would be $87.20

Step-by-step explanation:

Because if it is 20 % off you would multiply it by 0.2 which would get you 21.8

Then, 109 - 21.8 is 87.20

When a number divides into another number without a remainder, it s called a factor of that number. Lets say we want to find the common factors of two numbers, we get the factors of each one and compare them. The common factor is the one that is found in both lists

While The Highest common factor, is the highest factor number found in both lists.

b) 2b , 3b

Factors of 2b= 1, 2 and b

Factors of 3b=1, 3 and b

Common factors =1 and b

Factors of 5bc= 1, 5, b, c
