Solve the literal equation: Z = 4x/Y^2 + 3W for X

Mathematics

ra1l [238]3 years ago

Answer:

Z = 4X / Y^2 + 3W

Z - 3W = 4X / Y^2

(Z - 3W) * Y^2 = 4X

1/4 * (Z - 3W) * Y^2 = X

X = 1/4 * (Z - 3W) * Y^2

Subtract 3w from both sides:

z-3w = \dfrac{4x}{y^2}

Multiply both sides by y^2:

y^2(z-3w) = 4x

Divide both sides by 4:

\dfrac{y^2(z-3w)}{4} = x

in the year 2001, a person bought a new car for $22000. for each consecutive year after that, the value of the car depreciated b
igomit [66]

Answer:

To the nearest hundred dollars, the car will be worth $17,900 by 2005

Step-by-step explanation:

Firstly, we need to write the depreciation equation

We have this as:

V = I(1 - r)^t

V is the present value which is what we want to calculate

I is the initial value, the amount the cad was bought which is $22,000

r is the rate of change which is 5% = 5/100 = 0.05

t is the time difference which is 2005-2001 = 4

Substituting all these into the depreciation equation, we have it that

V = 22,000(1 -0.05)^4

V = $17,919.1375

To the nearest hundred dollars, that would be;

$17,900

Two families went to Rollercoaster World.
Alona [7]

Answer:

Children ticket cost $30 and adult ticket costs $40.

Step-by-step explanation:

Given that:

x = price of a child ticket

y = price of an adult ticket

According to given statement;

3x+2y=170     Eqn 1

4x+6y=360    Eqn 2

Multiplying Eqn 1 by 3

3(3x+2y=170)

9x+6y=510      Eqn 3

Subtracting Eqn 2 from Eqn 3

(9x+6y)-(4x+6y)=510-360

9x+6y-4x-6y=150

5x=150

Dividing both sides by 5

\frac{5x}{5}=\frac{150}{5}\\x=30

Putting x=30 in Eqn 1

3(30)+2y=170

90+2y=170

2y = 170-90

2y = 80

Dividing both sides by 2

\frac{2y}{2}=\frac{80}{2}\\y=40

Hence,

Children ticket cost $30 and adult ticket costs $40.
