Answer:
<em>x = 2.93</em>
Step-by-step explanation:
The sum of angles of the triangle is 180degrees, hence;
9x - 72 + 73x + 11 = 180
82x - 61 = 180
82x = 180 + 61
82x = 241
Divide both sides by 82
82x/82 = 241/82
<em>x = 2.93</em>
<em>Note that the functions might not be accurate but the same methos should be employed for any function given</em>
Answer: 16 science problem and 26 math problems
Step-by-step explanation: First, subtract 10 from 42. When you do this, you get 32. Next, divide 32 in half. You'll get 16 for each. Finally, add 10 to one of the 16's and you'll get 26 and 16.
Answer:
Step-by-step explanation:
so the problem is 7 cookies in 1 minutes which is 7 x1 but if we want to know how many we have in 2 minutes we would have to multiply by 2 not 1. so we do 7x2 which is 14. 14 cookies in 2 minutes
X^3 - 21x = -20
add 20 to both sides
x^3 - 21 x + 20 = 0
Rational Root Theorem:
Factors of P (constant) 20 = 1, 2, 4, 5, 10, 20
-------------------------------
Factors of Q (leading Coefficient) = 1
Possible zeros (all + -) 1/1, 2/1, 4/1, 5/1, 10/1, 20/1
Of the choices given only the number 1 is a possible root.
