Answer:the cost of one drink is $7
the cost of 1 bag of popcorn is $6.5
Step-by-step explanation:
Let x represent the cost of one drink.
Let y represent the cost of 1 bag of popcorn.
Aiden spends a total of $46.00 on 6 drinks and 1 bag of popcorn. This means that
6x + y = 46 - - - -- - - - - - -1
Jeremiah spends a total of $134.00 on 12 drinks and 8 bags of popcorn. This means that
12x + 8y = 134 - - - - - - - - 2
Multiplying equation 1 by 8 and equation 2 by 1, it becomes
48x + 8y = 368
12x + 8y = 134
Subtracting equation 2 from equation 1, it becomes
36x = 234
x = 234/36 = 6.5
Substituting x = 6.5 into equation 1, it becomes
6 × 6.5 + y = 46
39 + y = 46
y = 46 - 39 = 7
Answer: 5/6
Step-by-step explanation:
5/8 / 3/4
5/8 * 4/3= 20/24
20/24 / 4/4 = 5/6
All you have to do here is subtract 2 on both sides to isolate R.
R + 2 < 15
R < 13

First, factor the numerator:
Now, the inequality is
The equivalent inequality is
On the number line plot doted points -6, 0 and 2 and put signs +, -, +, - from the right to the left. Intervals with + signs are the solution of the inequality:
that is represented by D number line.
