Answer:

32.4

Step-by-step explanation:

So if we divide 54 by 5 we get 10.8 ( her height

then we multiply 2 by her height which is 10.8 and that will give us 21.6 .

the last step is subtracting, So we get Sharon's height which is 54 and subtract that by 21.6 and that will gives us 32.4! :D

Solve for the unknown variable: -8m - 9 = 39

Lemur [1.5K]

Answer:

m =-6

Step-by-step explanation:

To solve for the unknown variable, m, we have to get m by itself. Perform the opposite of what is being done to the equation.

-8m-9=39

9 is being subtracted from-8m, so add 9 to both sides. Addition is the opposite of subtraction.

-8m-9+9=39+9

-8m=39+9

-8m=48

-8 and m are being multiplied. Divide both sides by -8, because division is the opposite of multiplication

-8m/-8=48/-8

m=48/-8

m= -6

A grocery store estimates that customers arrive at the rate of 15 per hour. The cashier can serve customers at a rate 20 per hou

IrinaK [193]

Answer:

3 customers

Step-by-step explanation:

Rate of arrival (λ) = 15 per hour

Service rate (μ) = 20 per hour

The number of customers in a system given the arrival rate and the mean service rate is given by:

$N = \frac{\lambda}{\mu-\lambda}\\$

Applying the given data:

$N = \frac{15}{20-5}\\N=3\ customers$

The average number of customers in the system is 3 customers.

Write the equation 12 − y = 2x − 5 in slope-intercept form. What are the slope and y-intercept? A. y=2x−17,m=2, y-intercept (0,−

MrRissso [65]

Answer:

Step-by-step explanation:

12-y=2x-5

+5 +5 ( add 5 to both sides)

17-y=2x

-17 -17 (Subtract 17 to get y by itself)

-y=2x-17

divide by -1 because y cant be negative

y=-2x+17

m=-2 and y-intercept= 17

I hope thats right :)
