How many solutions does 5x + 4y = 6 10x - 2y = 7 have

Step-by-step explanation:

5x + 4y = 6

4y = -5x + 6

y = -5/4x + 24slope here is -5/4 and y int is 24

10x - 2y = 7

-2y = -10x + 7

y = 5x - 7/2slope here is 5 and y int is -7/2

if the slopes and the y int's are different, which they are, then there is 1 solution

ratio is 2 : 9

the answer is three

13.5 : 3

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
