To get the answer you should solve the following equation:



So, the 8 batteries cost
$13.84.
Answer:
D.
Step-by-step explanation:
the dot is right in between zero and one, which makes it 0.50
1.) answer: 5
Steps subtract 3 from both sides 8-3 is 5 so x is 5
2.) answer: -12
Because the 4 is positive you subtract it on the other side to cancel it out and -4 +-8 is -12 so x is -12
2/3 x * x = 864
(2/3) x^2 = 864
x^2 = 864 * (3/2) = 1296
x = + sqrt 1296 = 36
length is 36 feet
5/12 k=15/16
k=(15*12) / (16 * 5)
K=180/80=9/4
Answer: K=9/4
