Answer:
7
Step-by-step explanation:
Given the class interval :
Number of Social
Interactions
35-42
43-50
51-58
59-66
67-74
75-82
83-90
91-98
99-106
107-114
The class width = 7
The class width is the range between each class intervals :
42 - 35 = 4
114 - 107 = 7
106 - 99 = 7
Answer:
A. 
Step-by-step explanation:
No more than 110 lb total will be grilled. That means that the amount of meat that will be grilled is equal to or less than 110 lb.

The total weight is made up of the weight of the chicken legs plus the weight of the racks of ribs.
1 chicken leg weighs 1.25 lb.
x chicken legs weigh 1.25x.
1 rack of ribs weighs 7 lb.
y racks of ribs weight 7y.
The total weight of the meat is
1.25x + 7y.
That weigh must be less than or equal to 110 lb.

I searched it up on Google. Not sure how accurate the information may be though.
Answer:
5x - 4 = 11
1/2x + 15 = 9
Step-by-step explanation:
I dont exactly know how u would show work.
If it says something is less than a number, then it will be at the back of the equation. So skip that part and u will see it says five times a number. The number is unknown therefore it will a variable (i chose x to be the variable). 5 times x is 5x. Minus the 4 would be 5x - 4. Then it says the equation equals 11. So 5x - 4 = 11.
If it says something is more than a number, it can be on either side of the equation using the commutative property of addition. But if we want to consider it being like subtraction, then it also will be in the back of the equation. A half is one over two (1/2). A half of x is 1/2x. Plus the 15 would be 1/2x + 15. It then states that the equation equals 9. So 1/2x + 15 = 9.
