A and B share the cost in a ratio of 3:2. A pays £125, how much does B pay?

jolli1 [7]

Cross multiply then solve for x:

3/2 * 125/x

2*125 = 250
3 * x = 3x

3x = 250
x = 83.33 = 83 (rounded)

Which pairs of points would result in a line with a rate of change of 2:1? Select all that apply.

Helen [10]

Answer:

Options A, C, D are true.

Step-by-step explanation:

We have to choose the pair of points from that given in the attached file which will result in a line with a rate of change i.e. slope of 2:1 i.e. 2.

A. The points are (-4,-11) and (-2,-7).

Then the slope of the joining line is $\frac{-7-(-11)}{-2-(-4)} =2$

B. The points are (5,6) and (-5,12).

Then the slope of the joining line is $\frac{12-6}{-5-5} =-\frac{3}{5}$

C. The points are (0,-3) and (-4,-11).

Then the slope of the joining line is $\frac{-11-(-3)}{-4-0} =2$

D. The points are (0,-3) and (5,7).

Then the slope of the joining line is $\frac{7-(-3)}{5-0} =2$

Therefore, options A, C, D are true. (Answer)

The sum of the page numbers on the facing pages of a book is 629. what are the page numbers

jok3333 [9.3K]

So basically, these numbers have to be consecutive because they're facing pages.

So you can just divide this by 2, and then add one to the second number.

629/2 = 314 R1

So the first page number is 314, and for the second one, just add one, and you get 315.
