By replacing the term "a number" with a variable like x, you can get the equation 7x - x = -48. Then, further simplify the equation by combining like terms to equal 6x = -48. After that, divide both sides by six to get x alone, making your final answer x = -8.

Answer:
Number of Weeks - { 1, $120} {4, $480} {8, $960}
Step-by-step explanation:
First divide $1,800 by 15, which gives you 120. for for every week you add on $120. $120 times 4 gives us $480. 960 divided by 120 gives you 8 weeks. (i hope this helps :) )

Explanation:
The result of problem 7 is undefined because the matrices are not the same size. Both matrices must have the same number of rows, and they must have the same number of columns. This is so the terms match up when we add them. This applies to question 9 as well because subtraction is a form of addition.
For problem 8, we add the corresponding terms. So for instance, along the top we have -2+(-3) = -5 as the first entry in the top row. So that's why the answer is C for problem 8. Problem 10 and 11 are similar to this. Be careful to distribute the negative through to each term in the second matrix when subtracting matrices.
For problem 12, we multiply the outer 3 by each term inside the matrix. We end up with choice B.
I think it’s 92% not to sure tho
20 times 10=200 fluid ounces
128 fluid ounces per gallon
1 gallon is too little
2 gallons is to much
but you can't buy 1 and 72/100 of a bottle so just buy 2
2 bottles
