To measure the exact quantity of things ;)
Answer:
x + y = 9
5x + 2y = 30
Step-by-step explanation:
We're trying to find the number of sandwiches and bottles of water he buys and we know he bought 9 in total. This can be represented by x + y = 9 (since x represents the sandwiches and y represents the water). Knowing this, we know that sandwiches (x) cost 5 dollars and water (y) costs 2 dollars. We know he spent a total of 30 dollars. The second equation can therefore be represented by 5x + 2y = 30.
The expression given in the question can be simplified by getting them out of the brackets and then adding and subtracting the like terms. This will yeild the desired result.
<span>(-1+6i)+(-4+2i) = - 1 + 6i - 4 + 2i
= -5 + 8i
From the above deduction, it can be easily concluded that the correct option among all the options that are given in the question is the third option or option "c".</span>
