Answer: The system of equations are;
a + b = 9 ———(1)
a + 3b = 23———(2)
Step-by-step Explanation: The variables used here are a and b. Where a represents the number of free throws and b represents the number of three-pointers.
From equation (1), what we have is the total number of shots he has taken altogether which is 9 shots in all. All 9 shots are an addition of free throws and three pointers (that is a + b).
In equation (2), what we have is the points obtainable times the number of shots taken (for each shot). This means if a is a free throw, then 1 times a is equal to number of free throws times 1. Similarly, if b is a three-point throw, then 3 times b is equal to the number of three pointers thrown times 3.
The solution to the equation above gives us,
a = 2 and b = 7
Answer:
The total cost for 8 skiers=316 dollars
Step-by-step explanation:
Given that the expression 15n+12n+100 represents the total cost in dollars for skis,boots and a lesson for n skiers.
To simplify the given expression :
15n+12n+100=27n+100
27n=-100
Therefore 
Now to find the total cost for 8 skiers.
The total cost for 8 skiers can be written as below
Put n=8 in the given expression 15n+12n+100
15(8)+12(8)+100
=120+96+100
=316
Therefore the total cost for 8 skiers is 316 dollars
The total cost for 8 skiers=316 dollars
Answer:
Step-by-step explanation:
I have "and" but not "or"
"and" is when your talking about the decimal point for example:
1.2
one, and, two tenths
We can put the two equations together with substitution, and we get
3x + 2y = 30
Now we have a single equation in two variables, so we don't have enough information to solve for both x and y.
The answer would be A , that’s his slugging percentage ! Hope this helps !
