Answer:
Each family spent about 34.25 on dinner
Step-by-step explanation:
$167 - $30 (tip) = 137
137 ÷ 4 (for each family) = 34.25
BUT
if each family is seperate than they each spent about 11.75 on dinner
167 - (30 x 4) = 47
47 ÷ 4 = 11.75
I'm pretty sure the first one is the answer though
★ Inequalities ★
![10 < n < 11 \\](https://tex.z-dn.net/?f=10%20%3C%20n%20%3C%2011%20%5C%5C%20)
or n ∈ ( 10 , 11 )
Possible value can be easily obtained by generating an arithmetic mean
![n = \frac{10 + 11}{2} = 10.5](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7B10%20%2B%2011%7D%7B2%7D%20%20%3D%2010.5)
Else we've infinite numbers between them ,
According to density property of real numbers , we can have any real number satisfying the given inequality under condition 10 < n < 11
Which is true for infinite possible numbers
10.1 , 10.2 , ... INFINITY
Helen runs the longest distance in 4 days.
Helen (In 4 days): 2.75 x 4 = 11
Bill (In 4 days): 10
11 (Helen) > 10 (Bill), so therefore Helen runs the longest distance in 4 days.
Answer:
128, -256, -1024
Step-by-step explanation:
multiply 32 by 4, multiply 128 by -2, multiply -256 by 4
ABC = 180-120=60
ACB = 180-(40+60)=80
Therefore ECD= 80 as ACB and ECD are vertically opposite angles
the solution is A as that is where the graphs intersect each other
