Answer:
x=0
Step-by-step explanation:
first remove parentheses 11x + 22 + 3x +12 =34
then cancel equal terms 14x + 34 = 34
divide both sides by 14 14x = 0
solution x = 0
Answer:
B
Step-by-step explanation:
It opens downwards, so the parabola is negative. This also means the vertex of the parabola is the highest point, therefore it is a maximum.
7) 5x + 16.50 = 59
-16.50 -16.50 (Subtract 16.50 from both sides)
5x = 42.50
/5 /5 (Divide by 5 on both sides)
x = $8.50
8) 4 + 3x = 67
-4 -4
3x = 63
/3 /3
x = 21 stuffed animals
9) 20 + 3x = -4
-20 -20
3x = -24
/3 /3
x = -8
10) 18.9 - 2x = 9.9
-18.9 -18.9
-2x = -9
/-2 /-2
x = 4.5
(I'm not completely sure on number 10, but I hope this helps!)
