**Answer:**

((90*3)+(40*6))/9

=(90+90+90+40+40+40+40+40+40)/9

=66.66

Let x represent the amount of beef and y represent the amount of pork Mike used in recipe.

He used total 8 lbs of meat, so we can write:

x + y = 8

He uses 3:1 ratio of beef to pork, so we can write:

x :y = 3 : 1

x = 3y

Using this value of x in first equation, we get:

3y + y =8

4y = 8

y = 2

x = 3y = 3(2) = 6

**This means Mike used 6 lbs of beef and 2 lbs of pork for his recipe**

**Answer:**

The correct option is (b).

**Step-by-step explanation:**

We need to find the equivalent to -2(4-3x)+(5x-2)

Using the associative property,

-2(4-3x) = -2(4)+2(3x)

= -8+6x

So,

-2(4-3x)+(5x-2) = -8+6x +5x-2

taking like terms together,

-2(4-3x)+(5x-2) = 6x+5x-8-2

= 11x-10

**The equivalent expression is equal to (11x-10).**

**Answer:**

Physics isn't my strongest subject but I'll do my best to give you an explanation to help you get the answer!

**Step-by-step explanation:**

The equation is:

F = m g

where **m=mass** and **g = acceleration due to gravity** (gravitational force)

okay, lets substitute our numbers in the equation.

F (125N) = m g (25m/s^2)

'<em>m</em>' is our unknown.

g is equal to 625

**Answer:**

There is no solution for x in this question

**Step-by-step explanation:**

|x + 2| = 14-16

|x + 2| = -2

|x + 2| must be ≥0

Therefore, no solution for x
