Answer:
see below
Step-by-step explanation:
12(80 – x) = 816
Divide each side by 12
80-x = 816 /12
80-x = 68
Subtract 80 from each side
80-x-80 = 68-80
-x = -12
Multiply each side by -1
x = 12
James earned 80-12 = 68
It would be 57 minutes. Also love the Kenma profile picture!!
EXPLANATION: so 4:48 is almost an hr to 5:45. Just subtract 3minutes from an hr and you have your answer!

Answer:
(-4, 3)
Step-by-step explanation:
There are coordinate rules for reflection that really help me with these:
Reflection over x-axis -- (x, y) -> (x, -y)
Reflection over y-axis -- (x, y) -> (-x, y)
Reflection over y = x -- (x, y) -> (y, x)
Reflection over y = -x -- (x, y) -> (-y, -x)
Hope this helps :]
F(2a)=35
35=(2a)^2-1
35=4a^2-1
minus 35 from both sidse
0=4a^2-36
facor out 4
0=4(a^2-9)
factor differece of 2 perfect squares
0=4(a-3)(a+3)
set to zero
a-3=0
a=3
a+3=0
a=-3
a=-3 or 3
hope that's what you're looking for.
