Answer:
Yes, because P = 2x +2(12)
Step-by-step explanation:
As the formula for perimeter is 2(L+B).
Let L=x=18
B=12
Then, perimeter, P=2(18+12) = 2(30) = 60
Hence, we get the perimeter as 60 units.
Answer:
Fixed rate is $60.
Step-by-step explanation:
Let us consider per student charge be 'x'.
Let us consider fixed rate be 'b'
Given:
I rent a gym for $150 for 30 students.
So we can say that;
Total amount is equal to sum of number of students multiplied by per student charge and fixed rate.
framing in equation form we get;
Also Given:
another time I rent the gym for $270 for 70 students.
So we can say that;
Total amount is equal to sum of number of students multiplied by per student charge and fixed rate.
framing in equation form we get;
Now we will subtract equation 1 from equation 2 we get;
Dividing both side by 40 we get;
Now we will substitute the value of x in equation 1 we get;
So we can say that the equation can be written as;
Hence we can say that fixed rate is $60 and per student charge is $3.
35 or 37 represent 50% of 74
I think it would be 70 cm
