Answer: it would be 1 and 2

Step-by-step explanation:

It would be number two because to negatives make a positive like this.

16-(-12) is the same as 16+12 and 12-(-12) is the same as 12+12

4(x-3)=16

4x-12=16

4x=16+12

4x=28

x=7

Line segment GH is divided by point J in the ratio of 1:4. Endpoint G is at (7,5) and point J is at (10, 14).
wlad13 [49]

Answer:

(x2 , y2) = (22,50)

Step-by-step explanation:

Given:

m1 : m2 = 1:4

(x1 , y1) = (7 , 5)

(X ,Y) = (10 ,14)

Find:

(x2 , y2)

Computation:

X = (m1x2 + m2x1) / (m1+m2)

10 = [(1)(x2) + (4)(7)]/(1+4)

10 = [x2 + 28]/5

22 = x2

Y = (m1y2 + m2y1) / (m1+m2)

14 = [(1)(y2) + (4)(5)]/(1+4)

14 = [y2 + 20]/5

70 = y2 + 20

50 = y2

(x2 , y2) = (22,50)

William is setting up for folding chairs for a meeting he arranges the chairs and seven rows of the same link he has three chair
DiKsa [7]

Answer:

William has a total of 66 chairs.

Step-by-step explanation:

Let the number of chairs in each row be 'x'.

Also let the Total number of chairs be 'y'.

Given:

If he arranges the chairs in seven rows of the same length he has three chairs left

Number of rows = 7

Number of chairs left = 3

Now we can say that;

Total number of chairs will be equal to number of chairs in each row multiplied by Number of rows plus Number of chairs left.

framing in equation form we get;

y=7x+3

Also Given:

If he arranges the chairs in five rows of the same length he has 21 chairs left

Number of rows = 5

Number of chairs left = 21

Now we can say that;

Total number of chairs will be equal to number of chairs in each row multiplied by Number of rows plus Number of chairs left.

framing in equation form we get;

y=5x+21

Now we know that Total number of chairs are same.

Hence we can say that both the equations are equal.

7x+3=5x+21

Combining like terms we get;

7x-5x=21-3\\\\2x= 18

Dividing both side by 2 we get;

\frac{2x}{2}=\frac{18}{2}\\\\x=9

So we can that there are 9 chairs in each row.

Now to find the total number of chairs he has we will substitute value of x in any of the equation we get;

y =7x+3\\\\y=7\times9+3\\\\y=63+3 =66

Hence William has a total of 66 chairs.
