Answer:
x = 54
Step-by-step explanation:
-12(x + 4) + 14x = 60
i) distribute -12 to the whole parentheses of (x+4)
(-12 × x) + (-12 × 4) + 14x = 60
-12x - 48 + 14x = 60
ii) collect like terms
-12x + 14x - 48 = 60
2x - 48 = 60
iii) move constant to the right-hand side and change its sign
2x = 60 + 48
iv) add the numbers
2x = 108
v) divide both sides of the equation by 2
x = 54
Answer:
Step-by-step explanation:
You can understand the statement from many perspectives, but in terms of proposition logic it is best to understand it as "negation of a" or " b" in mathematical terms is written like this
You can show that they are logically equivalent because they have the same truth table.
Answer:
Sara should sell each bracelet at <em>$8.50</em> to make a profit of $99.
Step-by-step explanation:
We are given the following:
Total cost = $28.50
Total bracelets to be made = 15
Total profit to be made = $99
Let be the price at which Sara sells each bracelet to make a profit of $99.
Also,
Equating (1) and (2):
Sara should <em>sell each bracelet at $8.50</em> to make a profit of $99.
