Answer:
5
Step-by-step explanation:
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?
this can be solved using simultaneous equation. Two equations can be formed from the question
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
divide both sides of the equation by 5
b = 3
Substitute for b in equation 1
2a + 3(3) = 19
2a = 9 = 19
collect like terms
2a = 10
divide both sides of the equation by 2
a = 5
Answer:
what's the question
Step-by-step explanation:
....................
There is a given point (10,3) this shows that when the width (X) is 10, the height (Y) is 3.
On the left side of the graph, they show an equation for the height Hw as being the constant over w ( width).
Using the given point solve for the constant.
Replace Hw with 3 and w with 10:
3 = Constant/10
Solve for the constant by multiplying both sides by 10:
Constant = 3 x 10
Constant = 30
The answer is B.
62.5% of 8 is 5 so it's b
