Answer:
69.08
Step-by-step explanation:
round from 69.115
This is an example of a set defined by describing the property of its elements: every element in the set must be an integer, greater than or equal to -6, and less than zero (ecluded).
So, all the numbers that satisfy this requests are -6,-5,-4,-3,-2,-1, and the answer is thus b.
Considering the expression 4x + 12 = 64, it is found that:
A. The problem is that you purchased x fried pastry, costing $4, plus a chocolate and a soda, costing $12, and the total purchase cost was of $64.
B. The solution is x = 13.
C. The solution means that you purchased 13 fried pastry.
<h3>Expression</h3>
The expression is presented as follows:
4x + 12 = 64.
A possible context for this problem is:
- x fried pastry are purchased, each costing $4, hence 4x.
- A chocolate and a soda purchased, costing a total of 12, hence 4x + 12.
- The total cost of the purchase was of $64, hence 4x + 12 = 64.
The number of fried pastry purchased is the solution to the equation, calculated as follows:
4x + 12 = 64
4x = 52
x = 52/4
x = 13 -> 13 fried pastry were purchased.

C is correct.
1. You do 12.99 times 3
2. $0.69 times 2
3. Add $2.99 to the two prices above
4. Add the $2.52 tax to the prices
And you should get around $45 and some change
Answer:
Equation: 
.
It would take Martina 37 hours to earn $518
Step-by-step explanation:
✍️An equation that shows a proportional relationship between the time she spends babysitting (x) and amount of money she earns for babysitting (y) can be represented as 
, where k = constant of proportionality.
Let's find k using any of the pairs given in the table of values. Let's use (1, 14).
Substitute x = 1, and y = 14 into , and find k.
Substitute k = 14 into .
✅The equation would be:
.
✍️Using the equation, we can find how many hours Martina needs to work in order to earn $518 she wants to use to buy a new phone.
Simply, substitute y = 518 in .
Divide both sides by 14
✅Thus, it will take Martina 37 hours to earn $518
