Answer:
b) no solution
Step-by-step explanation:
What you always want to do in this type of problem is to combine all of your "like terms," where like terms are the part of your equation that have the same variable (or no variable). In this equation, we see three terms that have the variable "z". We can add the 12z + 15z on the left side to get 27z, and then we subtract 27z on both sides to cancel both of the 27z terms out.
Now, we are left with -6 = -5 (because we got rid of all the terms with the variable z in them). We know that -6 does not equal -5, and therefore, there is no number that we can assign to variable z such that the left side of the equation will equal the right side of the equation.
Therefore, there is no solution (because a solution to the equation would be a value that we can plug into the variable z to make the equation true).
Answer:
The current vice president (as of 4-16-2021) of the U.S. is Kamala Harris. This is a non-statistical question.
Step-by-step explanation:
A statistical question can be answered by collecting data and where there will be variability in that data. The proposed question (Who is the current vice president of the U.S.?) does not allow for variability in the data as there is only one legitimate answer to the question, thus it is NOT a statistical question.

here is the answer
A system of equations is a collection of two or more equations with a same set of unknowns.
Answer: Her account would earn $17.5
Step-by-step explanation: The earning on a given amount with simple interest can be computed as follows;
Interest = PRT/100
Where P is the principal (initial amount), R is the rate of interest and T is the number of years. The formula now becomes,
Interest = (50 x 3.5 x 10)/100
Interest = 1750/100
Interest = 17.5
Therefore, in 10 years her account would have earned $17.5
