Answer:

122

Step-by-step explanation:

12 times 2 times 5 plus 2 gets rewritten as

(12)(2)(5) + 2

Follow PEMDAS and do multiplication first.  From left to right...

 24(5) + 2                      {   (12)(2) = 24   }

   120 + 2                        {  (24)(5) = 120   }

  122                               {   120 + 2 = 122   }

Answer:122

Step-by-step explanation: The answer is 122 because 12 times 2 is 24 . Then you are going to multiply 24 times 5 because it's telling you that you have to multiply the first answer that you got times the number 5. 24 times 5 is 120. Then  you have to add 120 by 2 is 122.

       

12*2=24

24*5=120

120+2=122

Determine if the equations are parallel perpendicular or neither 10x-2y=16 and x+5y=-20
Inessa [10]

Answer:

perpendicular lines

Step-by-step explanation:

First, put both equations into slope-intercept form.

Lets start with 10x - 2y = 16

Remember that the slope intercept formula is y = mx + b

So, we must get y alone on one side.

First, subtract 10x from both sides

10x - 2y = 16

-2y = -10x + 16

Now, divide both sides by negative 2

y = 5x - 8

Now for our second equation.

First we must subtract x from both sides

x + 5y = -20

5y = -x - 20

Now, divide both sides by 5

y = -1/5x - 4

Now, both of our equations are in slope-intercept form

Here's how to determine if two equations are parallel or perpendicular

<em>Remember that the m in y = mx + b is our slope</em>

Parallel = same slope

Perpendicular = negative reciprocal slope

(ex: take the number 6                             take the number -3

negative reciprocal = -1/6                        negative reciprocal = 1/3)

If we look at the slopes in both of our equations, we see that there is a negative reciprocal slope (the slopes are 5 and -1/5)

So, these two lines are perpendicular. :)

Sonny substituted 5 for x in the proportion startfraction 16 over x endfraction = startfraction 48 over 15 endfraction and cross
frez [133]

The cross products of the proportion are equal.

According to the question, Sonny's equation can be written as follows.

16/x = 48/15

Now, the variable x is replaced by the constant 5. So the equation can now be written as follows.

16/5 = 48/15

When two fractions are equal to one another as shown above, the constants are cross multiplied with one another in order to form an equation.

16*15= 48*5

The values of both the products are equal which is 240.

Therefore, because the cross products of the proportion are equal.
