Answer:
10 to 15
Step-by-step explanation:
the spread is the start and stop of points data. It goes from the least point to the most point, here there is a dot (two technally) on 10 and a dot on 15 where the data stops so the data spread is 10-15
For example: if you chose to invite 10 people the skating rink would cost a total of $50 including the room fee
If you invite 10 people to the bowling alley you would spend $65 Including the room
The answer would be to choose the skating rink
Add two like terms: 16x+(-9x)=7x
Add 15 to both sides: 7x=28
Divide 7 on both sides: x=4
Answer:
8 grams
Step-by-step explanation:
The balance is in equilibrium, so the weights of the two sides are equal.
Let the weight of a square be s.
Left side: 2s + 4
Right side: s + 3(4) = s + 12
The weights are equal, so we set the two expressions equal.
2s + 4 = s + 12
s = 8
Answer: The weight of a square is 8 grams.
Question 2: The first step was the combine the like terms; in this example he is subtracting the 3x on both sides of the =.
Multiply 12 and 5 (by the same number) and add them to get whatever total ml of crayon wax is specified.
Ex: Total ml divided by 17, then find how many parts are red(12ml) and white(5ml)
