Answer:
Step-by-step explanation:
Adding equation 1 and 2 we have
-x=27
Therefore x= -27
Substituting the value of x into equation 2 we have
-108+y = 6
y = 114
Answer:
This one would be 2/3 ... the last option
If the ratio of boys to girls is 11:9 and there are 124 more boys than girls:
Let's say that the number of boys is 11x and the number of girls is 9x.
So, 11x = 9x + 124
2x = 124
x = 62
The total number of students = Number of boys + number of girls
= 11x + 9x
= 20x
= 1240 students
Thus, the total number of students attending the school is 1240.
Answer:
The sum of X divided by 4 and 8 is -16.
Step-by-step explanation:
The main numbers we are adding are X/4 and 8, so those can be referred to as "the sum of". X/4 is simply "X divided by 4".
This all equals -16, so we have:
The sum of X divided by 4 and 8 is -16.
Distribution Property.
Step-by-step explanation:
8(x+4)
8x+32
