Elevation above sea level = 2x+50
rock climbers minute of climbing = x
2x + x + 50
3x + 50
48 claims are rejected and 272 are accepted...
explanation
320/100= 3.2
3.2 * 15=48
320-48=272
The measure of ∠ACB will be 110°
<u><em>Explanation</em></u>
According to the diagram below, 
and 
are the perpendicular bisectors of 
and 
respectively and they intersect side 
at points 
and 
respectively.
So, 
and 
Now, <u>according to the 
postulate</u>, ΔAPE and ΔCPE are congruent each other. Also, ΔCFQ and ΔBFQ are congruent to each other.
That means, ∠PCE = ∠PAE and ∠FCQ = ∠FBQ
As ∠CPQ = 78° , so ∠PCE + ∠PAE = 78° or, ∠PCE = 
° and as ∠CQP = 62° , so ∠FCQ + ∠FBQ = 62° or, ∠FCQ = 
°
Now, in triangle CPQ, ∠PCQ = 180°-(78° + 62°) = 180° - 140° = 40°
Thus, ∠ACB = ∠PCE + ∠PCQ + ∠FCQ = 39° + 40° + 31° = 110°
Answer:
<h3>
Evaluating an expression</h3>
Unlike an equation, expression does not have an equal sign.
Example
(x² - 4²) / (x + 2)
So, by evaluating an expression it means to simplify the expression. Let's take a look at the example again
(x² - 4²)
= (x + 2)(x - 2) / (x + 2)
= (x - 2)
<h3>Solving an equation</h3>
Solving an equation involves finding an unknown value given in the equation. It contains an equal to sign (=) so, it result in a solution.
Example
(x² - 4²) / (x + 2) = 0
(x + 2)(x - 2) / (x + 2) = 0
(x - 2) = 0
x = 2
