x = 36.2 .
______________________________________________
Explanation:
________________________________________________
2x - 1 + 3x = 180 ;
Combine the "like terms" on the left-hand side of the equation:
________________________________________________
+2x + 3x = + 5x ;
_____________________________________
And rewrite:
_____________________________________
5x - 1 = 180 ;
_____________________________________
Add "1" to each side of the equation:
_____________________________________
5x - 1 + 1 = 180 + 1 ;
_____________________________________
5x = 181 ;
_____________________________________
Divide EACH SIDE of the equation by "5" ;
_____________________________________
5x / 5 = 181 / 5 ;
_____________________________________
to get:
_____________________________________
x = 36.2 .

Answer:
whatever the number of crocodiles is ___ multiply by 2 then add 4
____ x 2 = ____+4 =___
number of crocodiles____×2=___+4=__
( multiply symbol is x )
example : 5 crocodiles x 2 = 10 crocodiles + 4 = 14 turtles
Answer:
x < -6
Step-by-step explanation:
-5x - 8 > 22
Add 8 to both sides: -5x > 30
Divide both sides by 5: -x > 6
Divide both sides by -1 (reverse sign): x < -6
Answer: 0 0769
Step-by-step explanation:
Let x be the number of students that offer both subjects
15 - x + x + 13 - x + 9 = 26
-x + 37 = 26
-x = -11
x = 11
Number of student that offer english but not math = 13 - 11 = 2
The probability of english but not math = 2/26 = 0.0769
First of all, recall that y is a product of function of x. We have three factors:
The derivative of a product of function is computed by deriving one function at the time, and then adding all the results:
Let's compute the derivative of each function first:
Now plug f, f', g, g', h, h' in the formula above as required:
