It is systems of equations.
Let cups=c and l=liters
7c + 3l = 9.8
<span>5l - 9c = 6 </span>
<span>35c + 15l = 49 </span>
<span>15l - 27c = 18 </span>
<span>62c = 31 </span>
<span>c = 1/2 pint </span>
<span>l = 2.1 pint </span>
<span>1 cup = 1/2 pint 1 liter = 2.1 pints</span>
An obtuse angle would be an angle more then 90 degrees.
So if you add two angles together, it could be less then 90 degrees, such as 30 + 50 = 80 degrees.
However, it can also be more then 90 degrees, or an obtuse angle, for example 60 + 50 = 110 degrees.
So it's sometimes.
f ( x ) = - ( x + 1)^2 + 4

Answer:
1x+7
Step-by-step explanation:
7x+5-6x+2
7x-6x =1x
5+2=7
1x+7
6x40=$240 dollars a week
90dollars/$6 an hour =15 hours overtime
if andrew earned 330 dollars in 1 week he worked his regular40 hours and made $240+$90/$6 an hour he made working over time for 15 hours he must have worked 55 hours all together
