<h3>Answer: 56 minutes</h3>

1 hour = 60 minutes

The time values given, in minutes, are:

25, 55, 60, 94, and 46

going from monday to friday in that exact order

Add up the values, then divide by 5. This is because there are 5 values

So adding up the values gets us: 25+55+60+94+46 = 280

Then dividing by 5 leads to this answer: 280/5 = 56

note: you must convert the "1 hour" to "60 minutes" because each time value must be in the same units. Otherwise, its like mixing apples and oranges which makes no sense.

Factor x2 + 10x – 18. prime (x + 3)(x – 6) (x – 2)(x – 9) (x – 2)(x + 5)
Marta_Voda [28]

Answer:

prime

Step-by-step explanation:

x^2 + 10x – 18

What two numbers multiply to -18 and add to +10

There are no numbers that multiply to -18 and add to 10

-1 *18 = -18   -1 +18 = 17

-2 *9 = -18   -2 +9 = 7

This cannot be factored

Classify the system of equations and identify the number of solutions.
mestny [16]

Answer:

x = all real numbers

Step-by-step explanation:

first you need to solve the first equation to figure out what y is.

4x - y = 2

<em>add y to both sides of the equation</em>

4x = 2 + y

s<em>ubtract 2 from both sides of the equation</em>

4x - 2 = y

now that you know what y is, you can substitute it in the next equation.

3y = 12x - 6

3(4x - 2) = 12x - 6

<em>open the parenthesis </em>

12x - 6 = 12x - 6

<em>subtract 12x from both sides of the equation</em>

-6 = -6

regardless of what x is, -6 will always equal -6.

so, the answer is all real numbers.
