50% is exactly half, so to find half of something you just divide it by 2= 7.5
Or you could multiply it
15 x 0.50=7.5
<span>If x represent the number of nickels in the box and y represent the number of dimes in the box (note that x>0 and y>0), then the total value of x nickels is $5x and total value of y dimes is $10y. Adding these amounts of money you get that in money box was $</span><span><span>(5x+10y)</span>.</span>
<span> Sally knows that she has less than $20 in the box, then 5x+10y<2000 ($20=2000 cents).
</span>
Since this inequality is strict, then you should draw the dashed line 5x+10y=2000. The line divides coordinate plane into two parts.
Pick point (0,0) and consider to which part this point belongs. Since 5·0+10·0<2000, you can conclude that (0,0) is a solution of given inequality and belongs to needed part. Hence you should take the shaded part below the line for positive values of x and y.
i need the terms and definitions to answer this-
Answer: C
Explanation:
1/3(6+3i) - 2/3(6 - 12i)
= 2 + i - 4 + 8i
= -2 + 9i
\left. \begin{array} { l } { y = 112 + 6 }\\ { y = 73 + 2 }\\ { y = 72 + 10 }\\ { y = 3 x + 6 }\\ { \text{Solve for } z \text{ where} } \\ { z = 0 } \end{array} \right.
