Solve for x I need help again :/
Nostrana [21]

The Angles depicted 38° and (6x + 2)° are equal because they form vertical opposite Angle pair.

so,

  • 6x + 2 = 38

  • 6x = 38 - 2

  • 6x = 36

  • x = 36 ÷ 6

  • x = 6

A 3 pound pork loin can be cut into 10 pork chops with equal weight. How many ounces is each pork chop?
Misha Larkins [42]

Answer

Find out the how many ounces is each pork chop .

To prove

Relationship between pound and ounce .

1 pound = 16 ounce

As given

A 3 pound pork loin can be cut into 10 pork chops with equal weight.

Now for 3 pound pork loin = 3 × 16

                                            = 48 ounces

now 48 ounces of  pork loin can be cut into 10 pork chops with equal weight.

Than

weight\ of\ each\ pork\ chops = \frac{48}{10}

                                                         = 4.8 ounces

Therefore the weight of each ounce be 4.8 ounces .

Select the correct answer. Given the equations `9x + (3)/(4)y = 6` and `2x + (1)/(2)y = 9`, by what factor would you multiply th
Minchanka [31]

-3/2 is the  factor would multiply the second equation to eliminate y.

The correct option is (C).

<h3>What is factor?</h3>

A number or algebraic expression that divides another number or expression evenly—i.e., with no remainder.

Given equation is :

9x+3/4 y =6

2x+1/2 y =9

If we have to eliminate the y variable so we have to multiply it by factor -3/2

Then the second equation become

-3/2(2x+1/2 y =9)

-3x- 3/4 y =- 27/2

As we can see the y variable of both the equation is same.

Hence, -3/2 is the  factor would multiply the second equation to eliminate y.
