Use a transformation to solve the equation. k/-4 = - 0.8
A.
k = –3.2
B.
k = –0.2
C.
k = 0.2
D.
k = 3.2
Answers
make k the subject of the equation by multiplying through by -4,
this means, (k/-4) x -4 = - 0.8 x -4
this should give you k = -0.8 x -4, the negatives will cancel out to give you positive values,
so k= 3.2
your answer is D

Final answer:
By understanding the rate at which each oven bakes the bread, we can calculate that it would take the small oven 12 hours to bake the bread for one day.
Explanation:
To solve this problem, we need to first understand the rate at which each oven bakes the bread. When both ovens are working together, it takes 3 hours to bake a day's worth of bread. This means their combined rate of work is 1/3 of the day's bread per hour. However, when only the large oven is used, it takes 4 hours to complete the same amount of work. Therefore, the large oven's rate of work is 1/4 of the day's bread per hour.
Our goal is to find the small oven's rate of work. To do this, we subtract the large oven's rate of work from the combined rate of work. This leaves us with 1/3 - 1/4 = 1/12 of the day's bread per hour. Therefore, it would take the small oven 12 hours to bake the bread for one day on its own.

a 6foot cable is 15.50
so
x=cost per foot
y=cost of special connectors
3x+y=10.25
6x+y=15.50
make first equation negative and add to the first
3x=5.25
divide both sides by 3
1.75=x
so it costs 1.75 for a foot of cable
subtitue into first equation
3(1.75)+y=10.25
5.25+y=10.25
subtract 5.25 from both sides
y=5 dollars=cost of special so
4x+y=4(1.75)+5=7+5=$12
so the cost of a 4 foot cable is $12

3±95√3 is simplified as 167.5495 or - 161.5495
Step-by-step explanation:
Given expression;
3±95√3
This expression can be simplified as;
3±95√3 = 3 + 95√3 or 3 - 95√3
= 3 + 95(1.7321) or 3 - 95(1.7321)
= 3 + 164.5495 or 3 - 164.5495
= 167.5495 or - 161.5495
Therefore, 3±95√3 is simplified as 167.5495 or - 161.5495

Answer:
The absolute change in height between Pierre and Jennifer is 5 inches when rounded to the nearest inch.
Step-by-step explanation:
To find the absolute change in height between Pierre and Jennifer, you can subtract Jennifer's height from Pierre's height:
Pierre's height = 6'3" = 75 inches
Jennifer's height = 5'10" = 70 inches
Absolute change = Pierre's height - Jennifer's height
Absolute change = 75 inches - 70 inches
Absolute change = 5 inches
So, the absolute change in height between Pierre and Jennifer is 5 inches when rounded to the nearest inch.
