Assuming that Jeremy spent the entire $100 on the party supplies, here's the breakdown:
$100 - $30 = $70 remaining.
$70 - $10 = $60 remaining.
If he spent $60 on ten hats, and each hat was the same price, then each hat would have cost:

The equation is as follows:

Each hat was $6
Answer: b) 384 sq. in.
Step-by-step explanation:
Surface area of cube = 6a^2
= 6 (8)^2
= 6 x 64
= 384 sq. in.
Answer:
The distance from the house to the school is equal to 
Step-by-step explanation:
Let
A-----> the distance from house to the park
B----> the distance from the park to the school
C----> the distance from house to the school
so

we know that


so
Find the the value of C


therefore
The distance from the house to the school is equal to 
Answer:
Step-by-step explanation:
Given the original coordinate as C (-6, 9) and new coordinates after dilation as C' (-2, 3), we can see that the value of the new coordinates has reduces by a factor. Let the factor be k
For the x coordinates:
C' = kC
x' = kx
-2 = k(-6)
-2 = -6k
Divide both sides by -6
k = -2/-6
k = 1/3
For the y-coordinates:
y' = ky
3 = 9k
Divide both sides by 9:
3/9 = 9k/9
1/3 = k
k = 1/3
Hence the scale factor of the dilation is 1/3
That equation is unable to be graphed because a ^ cant be near -<span />
