Answer:
B) 0.2
Step-by-step explanation:
1/4 as a decimal 0.25
0.25 x 0.8 = 0.2!
c:
Answer:
x = 10
Step-by-step explanation:
Find x by isolating the variable, meaning get rid of every term until the variable, in this case it's x, is on one side of the equation and everything else is on the other side.
x - 2 = 8
Add +2 to both sides of the equation to cancel out the -2
x - 2 = 8
<u> +2 +2</u>
x + 0 = 10
x = 10
Answer:
63.5F
Step-by-step explanation:
Let x represent the temperature at the start of the experiment. Then the temperature at first check is (x -10.4F). The temperature at the second check is 1/3 that value, and is said to be 17.7F. This lets us write the equation ...
1/3(x -10.4F) = 17.7F
Multiplying by 3 gives ...
x -10.4F = 53.1F
x = 63.5F . . . . . . add 10.4F
The initial temperature of the liquid was 63.5F.

<em>Additional comment</em>
Temperature is measured on an "interval scale." On such a scale, the value 0 is located arbitrarily. Concepts such as "1/3 of the temperature" have no meaning on such a scale. Here, we have to ignore that fact and assume the problem is about the numbers, not about any real temperature relationship in thermodynamic terms.
The number is 19, 14+5=19 or 19-5=14
S=6
Solution
6/2=3
(6*4)=24
24-21=3
