Salma and Jared each threw 5 darts at the target shown. Salma scored 19 points by landing 2 darts in A and 3 in B. Jared scored 17 points by landing 1 dart in A and 4 in B. How many points are given for a dart landing in A?

5

Step-by-step explanation:

this can be solved using simultaneous equation

2a + 3b = 19  equation 1

1a + 4b = 17    equation 2

Multiply equation 2 by 2

2a + 8b = 34  equation 3

Subtract equation 1 from 3

5b = 15

b = 3

Substitute for b in equation 1

2a + 3(3) = 19

2a = 9 = 19

2a = 10

a = 5

Step-by-step explanation:

2a + 3b = 19 equation 1

1a + 4b = 17 equation 2

Multiply equation 2 by 2

2a + 8b = 34 equation 3

Subtract equation 1 from 3

5b = 15

b = 3

Substitute for b in equation 1

2a + 3(3) = 19

2a = 9 = 19

2a = 10

a = 5

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
