Depends what pen it is xD
Answer:
option 3 is the answer of this
<span>10!/4!*6!=(10*9*8*7*6*5*4*3*2*1)/4*3*2*1*6*5*4*3*2*1
10*9*8*7/4*3*2*1=5040/24=210</span>
Answer:
Part A: a coefficient is either 20 or 35, both work. A variable is c or w, again either work. The constant is 23.50.
Part B: He will have $503.50
Part C: The coefficient would change, because the amount per car changes, not the amount of cars.
Step-by-step explanation:
A coefficient goes in front of the variable (which is the letter, usually shown as x). The constant is a number with no variable attached.
We replace c with 20, and w with 12, giving us 20(3)+35(12)+23.50 for our equation. After multiplying, we come up with 60+420+23.50, which equals 503.50.
We determine the minimum and maximum scores that Juan needs to get in order to be within the strict average range. We let x be his score.
minimum:
74 = (82 + x) / 2
The value of x from the equation is equal to 66.
maximum:
80 = (82 + x )/2
The value of x from the equation is equal to 78.
Hence, Juan's score should fall between 66 and 78, inclusive.
Answer: <em> 66 ≤ x ≤ 78</em>
