Answer:
A
Step-by-step explanation:
2x² - 12x - 14
2(x² - 6x - 7)
2(x² - 7x + x - 7)
2(x - 7)(x + 1)
In order to solve this problem, we transform the statements into
algebraic expressions. First, we assign the variables.
Let:
x = Gina’s number
y = Sara’s number
For the first equation, we show that Gina’s number is greater
than Sara’s number by 2. For the second equation, we show that the sum of both
numbers is 68.
<span>(1)
</span>x – y = 2
<span>(2)
</span>x + y = 68
<span>We
add the two expressions, which result in the expression: 2x = 70. Then we
divide 70 by 2 to get the value of x. We then have x = 35. Using the second
equation, we solve for y = 68-35. This gives y = 33. To summarize, Gina’s
number is 35 while Sara’s number is 33.</span>
12t (that's the $12 for a shirt) + 25s (25 dollars for shorts) < (or equal too) 126
The combination cost for the shirts and shorts has to be less than or equal to $126
t + s > (or equal too) 5
The total number of items has to be greater then or equal too or equal to 5
Answer:
50 percent
Step-by-step explanation:
100 percent divided by 6 (the amount of data) is 16 2/3.
Each number represents 16 2/3 percent.
3 of the numbers are either 2 or 9.
16 2/3x3=50.001
The final answer is a 50% probability.
