Dx-y+ab=z solve for x

Mathematics
1 answer:
saul85 [17]2 years ago
4 0

Answer:

\huge x = \frac{z + y - ab}{d}

Step-by-step explanation:

dx-y+ab=z

First move (- y + ab ) to the other side of the equation

dx = z + y - ab

Divide both sides by d to make x stand alone

\frac{dx}{d}  =  \frac{z + y - ab}{d}  \\

We have the final answer as

x = \frac{z + y - ab}{d}  \\

Hope this helps you

Determine the constant of proportionality,k,of Kevin’s wage.
ankoles [38]

Answer:

Kevin's constant of proportionality,k = $8.25 per hour

Greg's constant of proportionality,k = $9 per hour

Savannah's constant of proportionality,k = $9.5 per hour

Step-by-step explanation:

1. What is the constant of proportionality, k, of Kevin's wage? Greg's? Savannah's?

Solution

y = kx is a proportional variation

Where,

y and x are represent two different variables

k represent constant of proportionality

From the attached table,

Let

y = wages earned (in dollars)

x = hours worked

To find the constant of proportionality k of Kevin's wage, divide the variable y (total earned) by the variable x (number of hours)

Using any points on the table

Take (8,66.00) for example

constant of proportionality k of Kevin's wage = variable y (total earned) / variable x (number of hours)

= 66.00/8

= 8.25

k = $8.25 per hour

B. Constant of proportionality of Greg's wage = variable y (total earned) / variable x (number of hours)

Using (9, 81.00)

k = 81.00/9

= 9

Greg's k = $9 per hour

C. Constant if proportionality of Savannah's wage = variable y (total earned) / variable x (number of hours)

Using (6, 57.00)

k = 57.00/6

= 9.5

Savannah's k = $9.5 per hour

Therefore,

Kevin's constant of proportionality,k = $8.25 per hour

Greg's constant of proportionality,k = $9 per hour

Savannah's constant of proportionality,k = $9.5 per hour

P’(rolling a number less than five and landing on tails)
Ksenya-84 [330]

Answer:

P’(rolling a number less than five and landing on tails) = 1/3

Step-by-step explanation:

dice has 6 numbers and you only want 4 of them, so you have a 4 in 6 chance of doing that which is equal to 4/6 or 2/3

a coin has 2 side so the chance of getting tails is 1 in to or 1/2

therefore the probability of getting a number less than 5 and a tails is

4/6 times 1/2 = 4/6 x 1/2 = 4/12 = 1/3

or you can do it this way:

2/3 times 1/2 = 2/3 x 1/2 = 2/6 = 1/3
