Answer:
Total temperature change = -32.48 degrees
Step-by-step explanation:
Over 11.2 hours, the temperature changed -2.9 degrees each hour.
Total time elapsed = 11.2 hour.
Temperature change per hour = -2.9 degrees
Total temperature change = Total time elapsed x Temperature change per hour
Total temperature change = 11.2 x -2.9 = -32.48 degrees
So temperature is reduced by 32.48 degrees in 11.2 hours.
Total temperature change = -32.48 degrees
Answer:
Y = -8.17
X= -4.936
For the first one
Step-by-step explanation:
4x=26+6y
X = 6.5+1.5y
5(6.5+1.5y)-4y = 8
32.5+7.5y-4y = 8
24.5=-3y
Y = -8.17
X= -4.936
To reduce a number by 12% we can simply multiply it by 0.88. If we repeat this 5 times we get 8, 7.04, 6.1952, 5.451776, 4.79756288, 4.2218553344.
We end up with 4.2218553344.
I think this is right.
Answer:
z/6+15=24
We move all terms to the left:
z/6+15-(24)=0
We add all the numbers together, and all the variables
z/6-9=0
We multiply all the terms by the denominator
z-9*6=0
We add all the numbers together, and all the variables
z-54=0
We move all terms containing z to the left, all other terms to the right
z=54
Step-by-step explanation: hope it helps
