Answer: 11m-3
Step-by-step explanation: Add -m and +12m to get 11m. Then add -17 and +14 to get -3.
Answer:
x ≈ 73.3
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos39° = 
= 
( multiply both sides by x )
x × cos39° = 57 ( divide both sides by cos39° )
x = 
≈ 73.3 ( to the nearest tenth )
Answer:
Step-by-step explanation:
I will assume you are solving for <em>z</em>. To solve for a variable, we are looking to get it alone on one side of the equals side, and everything else on the other side.
Here's the given equation:
Note, I turned the mixed fraction into an improper fraction. This will make it much easier to work with.
There are two terms on the left side: 
and 
. Only one of them has a Z in it, so lets move it to the right side of the equals sign. We can do this by subtracting each side by .
We can then combine like terms:
Then, we can divide each side by 2 to turn 2z into z:
Therefore,

Step-by-step explanation: Let's come up with points that would be on the graph of a str. line:
(0, 1/4), (1, 1 1/12), (2, 1 11/12), (and so on).
Assume that this is a line, a str. line, and not a curve.
The slope of this line is
1 11/12 - 1 1/12
m = ------------------------ = 10/12, or 5/6.
2 - 1
We now have the slope and y-intercept: slope = m = 5/6; intercept = 1/4.
The line is then y = (5/6)x + 1/4.
To answer this question, substitute 4 for x and calculate y:
y = (5/6)(4) + 1/4 = 20/6 + 1/4 = 40/12 + 3/12 = 43/12 inches.
That's 3 7/12 inches.
