Of 500 seventh grade students, 310 walk to school. What percent of seventh graders do not walk to school?

Answer:

A   -6

Step-by-step explanation:

Since y varies directly with x, then y = kx

                                                        -2 = 5k

                                                         k = -2/5

Now, y = (-2/5)15 = -6

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

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.  

Therefore, y = mx be the required equation.

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

Note: When being divided by a fraction, you can multiply the inverse of the fraction to find the result.

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.

10(-2)=y

-20=y

I would say its a 50/50 chance

Answer:

1/2 chance

Step-by-step explanation:

because theres 1,2,3,4,5,6

1,3,5 are odd numbers

there are 6 numbers total

so theres half a chance it will land on an odd number

Answer is in the picture:

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

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.

Answer:

slope = 4/=7

y int = -7

Step-by-step explanation:

slope = rise/run

slope = 4/-7

y int:

y = 4(0)-7

y= 0-7

y int = -7

The slope and y-intercept of the equation are 4 and -7 respectively.

The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.

The given equation of a line is y=4x-7.

By comparing y=4x-7 with y=mx+c, we get

m=slope = 4 and c=y-intercept=-7

Therefore, the slope and y-intercept of the equation are 4 and -7 respectively.

Step-by-step explanation:

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

Answer:

(12,-7)

Step-by-step explanation:

The required ordered pair of the pre-image of D'(4, -3) is D(12, -7).

Given that,
To determine the preimage of the ordered pair of D'(4, -3) by the translation, (x, y)  to (x – 8, y+4).

Coordinate, is represented as the values on the x-axis and y-axis of the graph.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Let the ordered pair of the preimage be (x, y)
Now,

according to the question,
x - 8 = 4
x = 12
y + 4 = -3
y = -7

Thus, the required ordered pair of the pre-image of D'(4, -3) is D(12, -7).

Answer:

96

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
