Answer:
The correct answer is d. (40, 60)
Step-by-step explanation:
To start using the linear combination method, you need a variable that will cancel out. To get this, we will multiply the second equation by -20 and then add together.
x + y = 100
-1.4x - y = -116
-----------------
-0.4x = -16
x = 40
Now that we have the value of x, we plug into one of the original equations to find y.
x + y = 100
40 + y = 100
y = 60
This is a problem using the Pythagorean theorem.
The square of the length required is 122 + 122 + 302 = 1188
The length is the square root of this number; I will leave it to you to extract the square root.
C=5/9 (95F-32)
C=5/9 (63)
C= 5/9 times 63/1= 35
Celsius= 35 degrees
There is the answer :) hope that helps more than the first person who answered lol
So we isolate p, to get the answer we do p=101-77, which is 24,
so p=24
