(6m-3)2 = 4-2(m+1)
12m-6 = 4-2m-2
10m-6 = 4-2
10m = 4-2+6
10m = 8
M = .8
Answer:
Dividing. Set up the equation. On a piece of paper, write the dividend (number being divided) on the right, under the division symbol, and the divisor (number doing the division) to the left on the outside. The quotient (answer) will eventually go on top, right above the dividend.
Answer: approximately 5.1818 pounds per square inch (psi)
========================================================
Work Shown:
P = pressure
T = temperature
The pressure is directly proportional to the temperature, which means P = k*T where k is some constant. As T goes up, P goes up as well, and vice versa. If P goes down, then T goes down too (or vice versa). In short, P and T go up together or go down together.
We're told that 6 psi (pounds per square inch) correspond to a temperature of 440 degrees F. This means P = 6 and T = 440 pair up. Let's use this P and T pairing to find k.
P = k*T
6 = k*440
6/440 = k
k = 6/440
k = 3/220
Therefore, the equation
P = k*T
updates to
P = (3/220)*T
--------------------
The last step is to plug in T = 380 to figure out the paired value of P
P = (3/220)*T
P = (3/220)*380
P = 5.1818 approximately
<span>So we want to know what is the sum of 5 feet 9 inches and 12 feet 3 inches. To know that we need to know that there are 12 inches in one foot. Now we add feet with feet and inches with inches: 5 + 12 feet 9 inches + 3 inches = 17 feet 12 inches = 18 feet 0 inches or just 18 feet.</span>
