I think the answer is B because that is the only answer that could make sense.
Answer:
150 and -2 are integers
6.6 and -1/2 are rational numbers
-√3 is an irrational number
Step-by-step explanation:
Answer:
n=-1
Step-by-step explanation:
distribute the 7 to n+4 to get 7n + 28 = 21. subtract 28 from both sides to get 7n = -7. divide both sides by 7 to get n=-1
you could also divide everything by 7 at the beginning to get n+4=3, then subtract 4 from both sides to get n=-1
Answer:
(a) 60 cups
(b) 5 cookies, 8 muffins and 4 cupcakes in each container
Step-by-step explanation:
Given
Let:

So:

Solving (a): The greatest number of containers to be used;
To do this, we first reduce the ratio to the lowest
C : M : K = 300 : 480 : 240
Divide by 60

<em>The ratio cannot be further reduced. Hence, he will use 60 cups</em>
Solving (b): The number in each cup
In (a), we have:

This means that;

<em> --- Cookies</em>
<em />
<em> --- Muffins</em>
<em />
<em> -- - Cupcakes</em>
