m=18 when r = 2.
Step-by-step explanation:
Given,
m∝
So,
m = k×,--------eq 1, here k is the constant.
To find the value of m when r = 2
At first we need to find the value of k
Solution
Now,
Putting the values of m=9 and r = 4 in eq 1 we get,
9 = 
or, k = 36
So, eq 1 can be written as m= 
Now, we put r =2
m = 
or, m= 18
Hence,
m=18 when r = 2.
Sorry for being late but the answer is B
Answer: $18 dollars left
Step-by-step explanation:
multiply $4 by 5 that gives you $20 then subtract $20 from $40
giving you $20 then divide $20 by seven and you can only get 2 chicken.
then subtract $20 from $40 then subtract that answer by 2 which leaves you with $18
Answer:
12
Step-by-step explanation:
Use the Pythagorean theorem, a² + b² = c², where a and b are legs of the right triangle and c is the hypotenuse.
T=2A+4
S=5A-8
If Tom and Sara are 10 years old,
10=2A+4
6=2A
3=A
