Answer:
Step-by-step explanation:
The two thermometers developed by cindy Grade and Gabriel Fahrenheit are shown in the attached photo
Let x = a certain temperature reading on the Gabriel Fahrenheit's thermometer
Let y = a corresponding temperature reading on the cindy Grade's thermometer
Interpolating the temperatures, it becomes
(212 - 32)/(212 - x) = (150 - 0)/(150 - y)
(212 - 32)(150 - y) = 150(212 - x)
180(150 - y) = 31800 - 150x
2700 - 180y = 31800 - 150x
180y - 150x = 31800 - 27000
180y - 150x = 31800 - 27000
180y - 150x = 4800
The scales will agree at a common reading. This is achieved by making x to equal y. Therefore
180x - 150x = 4800
30x = 4800
x = 4800/30 = 160
At a reading of 160, both scales will agree
Answer:
11
Step-by-step explanation:
5 and a half gallons is 11 half gallons
since 1 half gallon needs 1 salt pckt
11 half gallons will need 11 packets
Answer:
£12605.15
Step-by-step explanation:
Compound interest formula
34000(1-0.18)^5
A solution for a pair of lines means that they are equal to each other. This occurs when they instersect. Since the lines have the same slope, but are not the same line, they are parallel, so they will never intersect. This means there are zero solutions.
Hope this helps!

Also when we have a greater and equal to sign (), it will be a filled in circle.
Thats why its by.
