Answer:
I agree with both of them
Step-by-step explanation:
A dozen is 12 muffins. Therefore, you pay $3.00 for 12 muffins.
We know that you pay $3.00 for 12 muffins we need to find out how much EACH muffin cost. For that we need to divide $3.00 by 12 which is 0.25.
Now we need to know how much it will cost us for 16 muffins. We use our equation 16*0.25 which is 4. Elena said she will pay 4 so she is right.
Andre said he will buy 8 muffins so we use our equation again 8*0.25 which is 2. He said he will pay 2 so he is right.
Answer:
The value of x is 
.
Step-by-step explanation:
It is given that the inverse variation equation is
..... (1)
The value of y is 4 and the value of k is 7.
Substitute y=4 and k=7 in equation (1).
Divide both sides by 4.
Therefore the value of x is .
Answer:
30.8
Step-by-step explanation:
-9.240/-3 = 30.8 by simplifying...
since perimeter is the total of the length plus length plus width plus width:
L+L+W+W= 78 cm (given in the problem) as the total perimeter; and remember the length (we are told in the problem) is equal to 2 times width. so:
3 +2w+3+2w=78
6 +4w=78
6+4w-6=78-6
4w=72
w=18
