Answer:
170 tickets.
Step-by-step explanation:
Write formulas for the question.
Then use substitution.
So number of $3 tickets sold is 230. But they ask for the tickets bought in advance (i.e. the tickets sold for $2). Use substitution again.
M=-1
4m+2(m+1)=9m +5
4m+2m+2=9m+5
6m+2=9m+5
6m+2-6m= 9m+5-6m
2-5=3m+5-5
-3/3=3m/3
m=-1
Answer:
The variable 8. Equation is 16 + 12x = 112.
Step-by-step explanation:
We know that she spent $16 dollars on magazines, so we can put it in the equation (16 + x= ?). We also know that the total is $112, so we can also add that (16+ x= 112). We don't know how many books she got, but we do know how much they cost (16 + 12x=112. So that makes the books the variable (X).
To find the variable we need to take out the magazines from the price. 112-16=96. Now we're left with 12x=96. Now all we have to do is divide 96 by 12, which equals 8.
Sorry everything is so long, I tried to make it short as possible
Answer:
6'2
Step-by-step explanation:
Let me restate the given:
Diameter = 4 inches
height = 9 inches
The volume of a cone is formulated as V = (πr²h)/ 3
Since the formula uses a radius and the given is the diameter of a circle, then simply divide the diameter by 2 to get the radius.
r = 2 inches
Solve for volume of cone:
V = [ (3.14) (2)² (9) ] / 3
V = 37.7 in³
The answer is 37.70 in^3.
