Set this up as follows...
12x - 10 = 7x + 20
solve for x
X is 6
sub VW=7X with 7•6
VW=42
check by subbing also for UW
72 - 10 is 62
uV plus VW equals 62. it checks out.
Answer:
p=6
Step-by-step explanation:
First use the Distributive property to distribute the -3 to both (3p) and (6):
-84=-9p-18-2p
Now combine alike terms! (-9p-2p):
-84=-11p-18
Now add 18 to both sides!
-66=-11p
Now divide both sides by -11!
6=p
This can be rearranged to give you a final answer of p=6
1) To calculate maximum of f(t) function we first need to find derivative of it:
f(t)' = 10(e^(-t/8) + t*e^(-t/8)*(-1/8)) = 10(e^(-t/8) -t/8*e^(-t/8)) = 10e^(-t/8)(1-t/8)
the condition is:
f(t)' = 0 that means:
0 = 10e^(-t/8)(1-t/8)
10t/8*e*(-t/8) = 10*e^(-t/8)
t/8 = 1
t = 8
The answer is 8 days.
2) that percent we will get simply by expressing t=8 in our equation.
f(8) = 10*8*e^(-1) = 80/e = 29.43%
9(8 - x) = 3x Distribute/multiply 9 into (8 - x)
72 - 9x = 3x Add 9x on both sides
72 = 12x Divide 12 on both sides
6 = x
Your answer is A
[proof]
9(8 - x) = 3x
9(8 - 6) = 3(6)
9(2) = 18
18 = 18
Answer:
Step-by-step explanation:
So first you need to find to Constant of Proportionality and to do that you need to divide either 96 by 3 or 160 by 5. The answer you get is the first blank, then to find the second blank you take 14 and multiply it by the first answer.
