A-4=B
2+C=B
A+B+C=13
A=b+4
C=B-2
Plug in to equation 3
(B+4)+B+(B-2)=13
Rearrange
B=11/3
A=(11/3)+4= 23/3
C=(11/4)-2= 3/4
Answer:
She would have scored 75 points.
Step-by-step explanation:
Points scored in a basketball game vary directly with shots taken.
This means that this question can be solved by proportions, using a rule of three.
How many would she have scored if she takes 60 shots?
Using a rule of three:
50 points - 40 shots
x points - 60 shots
Applying cross multiplication:
Dividing both sides by 40
She would have scored 75 points.
Answer:
<h2> Combination</h2>
Step-by-step explanation:
In this case the order of selection does not matter since we are concerned in the number of ways possible a set of students (5) can be grouped for a project, we are going to be using combination technique
In permutation the order of selection matters hence will not give the desired result
If by 104 and 103 you meant 10^4 and 10^3 the difference would be 10 because you subtract them as exponents and get 10^1 which is just 10. If you meant 104 and 103 as they are then the difference would be 6 as 104 x 6 is 6 more than 103 x 6.
Answer:
3N + 4
Step-by-step explanation:
The number next to the parenthesis means that you multiply everything inside the parentheses by that number.
1/2(6N+8) = 3N+4
