Answer:
y = lnx / ln 7.
Step-by-step explanation:
x = 7^y
Take logarithms of both sides:
ln x = ln 7^y
ln x = y ln 7 ( because ln a^b = b ln a. One of the Laws of Logarithms).
y = lnx / ln 7.
Answer:
y=1 and x = 2
Step-by-step explanation:
Given equations are :
2x-2y = 2 ....(1)
5x+2y= 12 .....(2)
Adding equation (1) and (2),
2x+5x = 2+12
7x = 14
x = 2
Put the value of x in equation (!).
2(2)-2y = 2
4-2y=2
2=2y
y=1
So, the values of x and y are 2 and 1 respectively.
To convert temperatures in degrees Celsius to Fahrenheit multiply by 1.8 and add 32 so the paper has a typo you would multiply 25 x 1.8 = 45 + 32 = 77F so 25 C is 77 F but the way it says it we would all be dead because 25 x 8 = 200 + 32 = 232 F it would be to hot for life. So the correct answer is 77°F Hope this helps! ;D
