Answer:

-4

Step-by-step explanation:

We have the coordinates (6, 3) and (8, 4), allowing us to calculate the slope (or gradient). To do this, you divide the change in y by the change in x, which is 1/2 which is a half.

The form of a linear equation is y = mx + c, where m is the gradient and c is the y-intercept.

We have the gradient, so we can put it in the equation:

y = x/2 + c

We can now substitute in a pair of our coordinates and rearrange to find the y-intercept.

3 = 6/2 + c

3 = 3 + c

c = 0

Therefore the equation for our line is y = x/2.

We can now put in the y coordinate we were given to work out the corresponding x coordinate:

-2 = x/2

x = -4

Therefore n is -4.

Answer:

His original farm was 333 1/3 acres

He has 66 2/3 acres of his land left

Step-by-step explanation:

Lex

His total farmland = x

1/2 of x = Mr frost

100 acres = Mr slate

Remaining = 1/5x

His total farmland = Mr Frost + Mr slate + remaining farmland

x = 1/2x + 100 + 1/5x

x = 5x+2x/10 + 100

x = 7/10x + 100

x - 7/10x = 100

10x-7x/10 =100

3/10x = 100

Divide both sides by 3/10

x = 100 ÷ 3/10

= 100 × 10/3

= 1,000/3

= 333 1/3 acres

His original farm was 333 1/3 acres

He has 1/5 of his original farm

1/5 × 1000/3

= 1,000 / 15

= 66 10/15

= 66 2/3 acres

He has 66 2/3 acres of his land left

Answer:

The coordinates of the point one half the distance is (6,1)

Step-by-step explanation:

Here we want to calculate the coordinates one half of the line segment.

This in another way simply means the coordinates of the midpoint of that segment;

Mathematically;

we proceed with this using the midpoint formula

(x,y) = (x1 + x2)/2, (y1 + y2)/2

From the question (x1,y1) = (5,-6) while (x2,y2) = (7,8)

let’s say

(x,y) = (5 + 7)/2 , (-6 + 8)/2

(x,y) = 12/2, 2/2

(x,y) = (6,1)

Answer:

[tex]b = 90w[/tex]

Step-by-step explanation:

Required

Determine the relationship

Represent the workers with w and bricks with b

First, we need to determine the constant of proportionality using:

[tex]b = kw[/tex]

Solve for k

[tex]k = \frac{b}{w}[/tex]

When w = 1; b = 90:

[tex]k = \frac{90}{1}[/tex]

[tex]k = 90[/tex]

When w = 2; k =180

[tex]k = \frac{180}{2}[/tex]

[tex]k = 90[/tex]

Notice that [tex]k = 90[/tex] in both cases;

Substitute 90 for k in [tex]b = kw[/tex]

[tex]b = 90w[/tex]

Hence; the relationship is [tex]b = 90w[/tex]

Answer: Choice D.  P = i/rt

This is the same as saying P = i/(rt). The parenthesis are preferred in my opinion to indicate we have rt in the denominator and not just r.

======================================

Explanation:

In the original equation, prt is the same as p*r*t. So we multiply p, r and t to get prt.

This can be thought of as p*(rt). To isolate p, we undo the multiplication done to the variable p. We will divide both sides by rt to get

i = prt

i = p*(rt)

i/(rt) = p*(rt)/(rt) ... dividing both sides by rt

i/(rt) = p

p = i/(rt)

Answer:

Area = 14276

Step-by-step explanation:

Length = 2w-6

Width =w

perimeter = 2w+ 2l =504

2w+2(2w-6)=504

2w+4w-12=504

6w=516

w=86

L=2w-6

L=2(86)-6

L = 172-6

L = 166

Area = L*W

area=86*166

Area = 14276

Answer:

-64

Step-by-step explanation:512 divided by 2 can be calculated as follows. 512/2 math problems division = 256. Therefore 256 to 2 decimal places= 256. 512/2

The quotient of the equation when A = 512 / -8 = -64

Given data ,

Let the quotient of the expression be represented as A

Now , the value of A is

Let the first number be represented as p

Now , the value of p = 512

Let the second number be represented as q

Now , the value of q = -8

where A = p/q

On simplifying the equation , we get

A = 512 / ( - 8 )

A = -512 / 8

A = -64

Therefore , the quotient of the expression is A = -64

Hence , the expression is A = -64

Step-by-step explanation:

pls mark brainlest ;)

The money left with Lupe after her purchase is $7.15.

Given,

Lupe had $100 to buy party supplies for her little sister's birthday.

She bought 12 bags of party favors and 15 party hats.

Each bag of party favors costs $5.30.

Each party hat cost $1.95.

We need to find how much money Lupe has left after her purchases.

We will subtract the amount spent from the total amount given.

The number of spending may depend on the number of items bought and the cost of each item.

If one item cost = $a

And number of items bought = 2

The total amount spent = 2 x $a = $2a

Find the amount Lupe has.

= $100

Find the cost of one party bag.

= $5.30

Find the cost of one party hat.

= $1.95

Find the number of the party bags.

= 12

Find the number of the party hats.

= 15

Find the cost of 12 party bags.

= 12 x $5.30

= $63.6

Find the cost of 15 party hats.

= 15 x $1.95

= $29.25

Find the money left.

= $100 - ($63.6 + $29.25)

= $100 - $92.85

= $7.15

Thus the money left with Lupe after her purchase is $7.15.

Answer: A and B

Step-by-step explanation: They both give 2 points and since a is cords it has to have a x/y axis but C just has two number rows

Answer:

Step-by-step explanation:

x    - an integer

then: 2x is an even number and 2x+1 is an odd number

consecutive odd numbers increase by 2  (even numbers too)

so the next odd number (the middle number) is:

2x+1+2 = 2x+3

and the third (the largest) consecutive is:

2x+3+2 = 2x+5

the sum of the smallest and the middle numbers is:

2x + 1 + 2x + 3

3 times the largest number is:  

3(2x + 5)  

the sum of the smallest number and middle number is 27 less than 3 times the largest number, so:

2x + 1 + 2x + 3 = 3(2x + 5) - 27

4x + 4 = 6x + 15 - 27

    -6x       -6x

-2x + 4 = -12

    -4       -4

 -2x  = -16

 ÷(-2)    ÷(-2)

   x = 8

2x+1 = 2•8+1 = 17

2x+3 = 2•8+3 = 19

2x+5 = 2•8+5 = 21

Check:

2x+1+2x+3 = 16+1+16+3 = 36

36+27 = 63

63:3 = 21 = 2x+5
