Answer:
x = 5
Step-by-step explanation:
4x + 2 = 2(x + 6)
4x + 2 = 2x + 12 (after you distribute the 2)
add and subtract like terms
4x - 2x = 12 - 2
2x = 10
x = 5
you can double check by substituting the x with 5 in the equation
4 (5) + 2 = 2(5 + 6)
20 + 2 = 2(11)
22 = 22
If you use the inverse operation that it subtraction so 12 minus 4 is 8 so if u substitute 8 for x, 8 + 4 is 12
Answer: men = 15 , women = 12
Step-by-step explanation:
Ratio of men to women = 5:4
Total ratio = 9
number of people = 27
number of men = ration of men / total ratio x total number of people
That is :
number of men = 5/9 x 27
number of men = 3
Number of women = ratio of women / total ratio x number of people
That is :
number of women = 4/9 x 27
number of women = 12

Answer:
15/23
Step-by-step explanation:
In total, Martina has a collection of 10 + 5 + 8 = 23 movies. 23 is the total number of outcomes, so that shall be the denominator. Now, she has 10 + 5 = 15 movies that aren't drama. Since this is the number we're counting, this will be the numerator. The probability as a fraction, thus, will be 15/23.
