Step-by-step explanation:
The angles (8x + 28) and (4x - 7) are supplementary to each other so we can write
or
Also, note that the angle (4x - 7) and 
are vertical angles, which means that they are equal to each other. Therefore,
The known figures that make up this unknown figure are a trapezoid and a half circle.
Answer:
Ezra will have 5 ounces of water leftover
Step-by-step explanation:
I first divided 4,005 by 16 to get 250.3125, which I rounded to 250. Then I multiplied 250 by 16 to get how many ounces Ezra used, which is 4,000. Then I subtracted that value from how many ounces she had to get how many she had leftover.
2x-5y= -5
-2/*x+2y=11
2x-5y= -5
-2x-4y= -22
+------------------
-9y=-27
y=3
x+2y=11
x+2*3=11
x=5
