So you have to isolate x.
First, move the 8 over, so it looks like: x/2=-12-8
Then to get rid of the 2 on the left hand side, you go:
x=-12-8 x2
x=-20x2
x=-40.  I think.

First subtract 8 from both sides 
leaving you with x/2 = -20 
Then multiply both sides by two to get rid of the denominator
which leaves you with x = -40

Write a let statement, an equation, solve: Jeremy is 14 years old. This is 4 1/2 years more than half his sisters age. How old i
Art [367]
J = 14
J = 1/2S + 4 1/2

14 = 1/2S + 9/2....multiply everything by 2 to get rid of fractions
28 = S + 9
28 - 9 = S
19 = S

check...
14 = 1/2S + 9/2......S = 19
14 = 1/2(19) + 9/2
14 = 9 1/2 + 9/2
14 = 19/2+ 9/2
14 = 28/2
14 = 14 (correct)

so the sister is 19 <===

The marginal profit in dollars on Brie cheese sold at a cheese store is given by Upper P prime (x )equals x (60 x squared plus 9
blondinia [14]

Answer:

Part A:

P(x)=15x^4+30x^3-50

Part B:

P(4)=$4270

Step-by-step explanation:

Part A:

In order to find the profit function P(x) we have to integrate the P'(x)

P'(x)=x(60x^2+90x)

P'(x)=60x^3+90x^2

\int\limits {p'(x)} \, dx =\int\limits {60x^3+90x^2} \, dx

P(x)=15x^4+30x^3+C

when x=0, C=-50

P(x)=15x^4+30x^3-50

Part B:

x=4

P(x)=15x^4+30x^3-50

P(4)=15*4^4+30*4^3-50

P(4)=$4270

Profit from selling 400 pounds is $4270

Answer:

V = 904.32 ft^3

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

The radius is 6 and pi = 3.14

V = 4/3 ( 3.14) (6)^3

V = 904.31999 ft^3

Rounding to the hundredths place

V = 904.32 ft^3

If each lap in a pool is 100 meters long, how many laps equal 1 mile? (1ft= 0.3048 meters
Tresset [83]
1 mile=1,609.34 meters
because each lap is equal to 100m it might be 16 laps
16 laps =1600m which is almost equal to 1609.34m
I think there's not a exact number of laps. you can try with your own calculations you'll end up with some decimal remaining.
I hope this will help.
