7x + 3y = 30
-2x + 3y = 3....multiply by -1
-----------------
7x + 3y = 30
2x- 3y = -3 (result of multiplying by -1)
----------------add
9x = 27
x = 27/9
x = 3
7x + 3y = 30
7(3) + 3y = 30
21 + 3y = 30
3y = 30 - 21
3y = 9
y = 9/3
y = 3
solution is (3,3)
Answer:
.
Step-by-step explanation:
You are trying to find 
.
When a number has a negative exponent, that means that the number becomes a fraction. That sounds confusing, so let me show you what that would be...
And since the 10x is being raised to the third power, it is the same thing as saying 10^3 * x^3. So, you would have...
= 
=
And that's your answer!

No, because 72*3 is 216. In order for it to be the right amount, the number of sugar cones must be 3 times the amount of the number of waffle cones.
Answer:
b). Reject the null hypothesis and conclude the means are different.
Step-by-step explanation:
A hypothesis is characterized as null when the data/statistics display that there is no distinction between the particular features of the groups. As per the details provided, the decision would be to 'reject/deny the null hypothesis and deduce that the means of the processes are different.' This <u>shows that there is no association among the variables due to the distinction in the means of the two processes and other data provided</u>. Thus, <u>option b</u> is the correct answer.
