Sarah:

Robert

Answers

Answer:

James = 119 points

Sarah = 357 points

Roberts = 51 points

Step-by-step explanation:

Given that :

James = x points

Sarah = 3x points

Roberts = x - 68 points

Each point = 3 pence

All students have a total of £15.81

1 pound = 100 pence

£15.81 pound = 1581 pence

3x + 3(3x) + 3(x - 68) = 1581

3x + 9x + 3x - 204 = 1581

15x - 204 = 1581

15x = 1581 + 204

15x = 1785

x = 1785 / 15

x = 119

Hence,

James = 119 points

Sarah = 119 * 3 = 357 points

Roberts = 119 - 68 = 51 points

Step-by-step explanation:

sorry. i feel so bad

To compute the amount of money the worker receives for any number of work-related miles, the equation is y = mx.

What is an equation?

Two algebraic expressions having same value and symbol '=' in between are called as an equation.

Given:

Let x be the number of miles a worker drove.

And y be the total amount of money.

And if he works m miles,

then the equation is,

y = mx

The above equation is will be used to compute the amount of money the worker receives for any number of work-related miles.

Answer:

Step-by-step explanation:

First we have to see how the pattern is increasing.

How did the sequence of numbers get from -3 to 6?

Try adding first.

To get from -3 to 6, add 9.

Move on to the next nunber.

Can we get from 6 to -12 through the same pattern (adding 9)?

No, so addition is not the pattern.

Next try multiplication.

To get from -3 to 6, multiply -2.

Move on to the next number.

Can we get from 6 to -12 through the same pattern (multiplying by -2)?

Yes!

Check the other numbers.

-12 × -2 = 24

24 × -2 = -48

Do they meet the pattern?

Yes!

To find the next number in the sequence, use the pattern: multiply the previous number by -2.

-48 × -2 = 96

At 9AM a train traveling 60 miles per hour leaves Los Angeles for San Francisco, a distance of 400 miles. At noon a car traveling at an average speed of 40 miles per hour leaves San Francisco for Los Angeles. At what time will the two vehicles pass each other?
ANSWER PLS

Answers

Answer is in the picture:

At 2:02 PM the two vehicles pass each other.

What is the speed?

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

Given thta,

Los Angeles to San Francisco:

rate = 60 mph ; distance = x miles ; time = d/r = x/60 hrs

San Francisco to Los Angeles:

rate = 40 mph ; distance = 400-x ; time = d/r = (400-x)/40 hrs

So, equation is

x/60 = (400-x)/40 + 3

x/60 = (400-x)+120/40

40x = 60[(400-x)+120]

40x=24000-60x+7200

100x=31200

x=312 miles

Now, time = 312/60

= 5.2 hours

Clock time = 9+5.2

= 14.2 hours

= 2:02 PM

Therefore, at 2:02 PM the two vehicles pass each other.

Answers

The number of 1/8s which are in 25 as required to be determined is; 200.

What is the number of 1/8s in 25?

It follows from the task content that the number of 1/8s in 25 as required in the task content is to be determined.

It follows from arithmetic principles that the number of 1/8s in 25 can be determined by evaluating; 25 ÷ 1/8

= (25 × 8) / 1

= 200.

Therefore, the number of 1/8s in 25 is; 200.

Also, if the number of 1/8s in 25 is to be determined; the multiplication equation to check the answer is; 1/8 × 200 = 25....which holds true.

Answers

Answer: x=-2

Y= -20

Step-by-step explanation

You replace the y in the second equation with 10x. This is because it says 10x=y

2x+10x=12x so you put that

12x=-24

To get x by its self you divide by 12.

-24 divided by 12 is -2.

Now you plug in -2 to either equation as y. I chose the first one because it's easier.

The top walking deck of a ship is 120 ft long. This is only 3/11 of the length of the ship. What is the length of the ship

Answers

Answer: 440 ft

Step-by-step explanation:

The top walking deck is 120ft long and yet comprises only 3/11 of the ships total length.

Assuming the total length of the ship is x ft long, the expression would therefore be:

x * 3/11 = 120 ft

The above shows that if x is multiplied by 3/11 it will give a distance of 120ft which is the top walking deck length.

Solving for x:

x * 3/11 = 120

x = 120 ÷ 3/11

x = 120 * 11/3

x = 440 ft
