Answer:1) First, add or subtract both sides of the linear equation by the same number.

2) Secondly, multiply or divide both sides of the linear equation by the same number.

3)* Instead of step #2, always multiply both sides of the equation by the reciprocal of the coefficient of the variable.

Using the addition or subtraction property, write the equation with all terms containing the unknown in one member and all terms not containing the unknown in the other.

What is the surface area?<br> 6 m<br> 6 m<br> 6 m<br> What is the answer

Slav-nsk [51]

Answer:

Answer is 216m^2

Step-by-step explanation:

You would do the formula 2(6*6) + 2(6*6) + 2(6*6)

To get a total of 216m squared!

Yea shop sells 60 teas in total. 9 of them are caffeinated. What percent is caffeinated

Digiron [165]

Answer:

15% of the teas are caffeinated

Step-by-step explanation:

Use the formula:

part/whole = t/100%

where t will be representing the percent of caffeinated tea.

Plug in the given to the formula shown above:

9/60 = t/100

Solve using cross product

(9 x 100) = (60 x t)

900/60 = 60t/60

15 = t

How do I start this problem? I don't need help with the graphing part.

tamaranim1 [39]

Answer:

x = 6 , y = 0 (x , y) = (6 , 0)

x = 12, y = 3 (x , y) = (12 , 3)

x = 24, y = 9 (x , y) = (24 , 9)

Step-by-step explanation:

Simply plug in a x, and find a y that would make the equation true:

When x = 6:

6 - 2y = 6

6 (-6) - 2y = 6 (-6)

-2y = 0

(-2y)/-2 = (0)/-2

y = 0

When x = 6, y = 0 (x , y) = (6 , 0)

When x = 12:

12 - 2y = 6

12 (-12) -2y = 6 (-12)

-2y = -6

(-2y)/-2 = (-6)/-2

y = 3

When x = 12, y = 3 (x , y) = (12 , 3)

When x = 24:

24 - 2y = 6

24 (-24) - 2y = 6 (-24)

-2y = -18

(-2y)/-2 = (-18)/-2

y = 9

When x = 24, y = 9 (x , y) = (24 , 9)

function travelSpeed = CalculateTravelSpeed(startX, startY, endX, endY, travelTime) % startX, startY: Starting coordinates % end

Ilia_Sergeevich [38]

Answer:

The functions in Python is as follows:

from math import *

def CalculateTravelSpeed(startX,startY,endX,endY,travelTime):

travelSpeed = EuclideanDist(startX, startY, endX, endY) / travelTime

return travelSpeed

def EuclideanDist(startX, startY, endX, endY):

dist = sqrt((startX - endX)**2 + (startY - endY)**2)

return dist

Step-by-step explanation:

from math import *

This defines the CalculateTravelSpeed function

def CalculateTravelSpeed(startX,startY,endX,endY,travelTime):

This calls the EuclideanDist function to calculate the distance; Next, the speed is calculated

travelSpeed = EuclideanDist(startX, startY, endX, endY) / travelTime

This returns the calculated speed

return travelSpeed

This defines the EuclideanDist function

def EuclideanDist(startX, startY, endX, endY):

This calculates the distance from the given coordinates

dist = sqrt((startX - endX)**2 + (startY - endY)**2)

This returns the calculated distance

return dist
