Answer:
(y+b)/a = x
Step-by-step explanation:
y = ax − b
Add b to each side
y+b = ax − b+b
y+b =ax
Divide each side by a
(y+b)/a = ax/a
(y+b)/a = x
Answer:
A
Step-by-step explanation: The rest of the answers are multiples of 2, and even numbers cannot be a prime
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.
