Answer:
40
Step-by-step explanation:
(35/100) of X = 14
(7/20) × X = 14
X = 14 × 20/7
X = 40
-(-2x-6y=-16)
2x+6y=16
4x-6y=-58
Y's cancel out, then add the rest
6x=-42
divide both sides by six
x=-7
plug x into any previous equation
2(-7)+6y=16
-14+6y=16
6y=30
y=5
Answer:
k = -3
Step-by-step explanation:
-7(2 + k) = 7
Divide both sides by (-7)
2 + k = 7/-7
2 + k = -1
Subtract 2 form both sides
k = -1 - 2
k = -3
12 pack for 8.5
6 for 5.75
5.75x2=11.5
12 pack is a better buy
