Answer:
The answer is A). I took the test on usatestprep
Step-by-step explanation:
1)
3 * 6 = 18
72 - 18 = 54
54/6 = 9
The club made 9 pies to sell.
2)
19 - 3 = 16

6/3 = 2
He spent $2 on each pencil.
Answer:
Option D)Neither solution is extraneous.
Step-by-step explanation:
we have

we know that
two possible solutions are x=-7 and x=1
<u><em>Verify each solution</em></u>
Substitute each value of x in the expression above and interpret the results
1) For x=-7


----> is true
therefore
x=-7 is not a an extraneous solution
2) For x=1


----> is true
therefore
x=1 is not a an extraneous solution
therefore
Neither solution is extraneous
All internal angles in a quadrilateral add to 360
so
x+110+110+70=360
x+290=360
minus 290 both sides
x=70 degrees
