Answer:

Step-by-step explanation:

Let the number = x

1/3x - 5= 2x             Multiply both sides by 3

1*x - 5*3 = 2x*3      Expand and collect like terms.

x - 15 = 6x                Subtract x from both sides

x - x - 15 = 6x-x        Collect like terms

- 15 = 5x                   Divide both sides by 5

-15/5 = 5x/5             do the Division

- 3 = x

Check

1/3(-3) - 5 = 2(-3)

-1 - 5 = - 6

- 6 = - 6

which checks.

PLZ HURRY!!!!!!!!! The table shows the number of candies packed by machine J. The equation shows the number of candies packed by
alekssr [168]
First, we need to make a function out of the table.  This function will be in slope-intercept form.  The function is y = 30x  so in 11 minutes Machine J will make 330 candies.  In 11 minutes Machine K will make 286.  subtract 286 from 330 to get 44.  Machine J will make 44 more candies than machine K in 11 minutes.

What is the slope of a line perpendicular to the line whose equation is x – 2y = 12.
natulia [17]

Answer:

-2

Step-by-step explanation:

x – 2y = 12

-2y = -x + 12

y = 1/2x - 6

Slope in above equation is 1/2. If you want the slope of a perpendicular line take the inverse opposite which makes it -2/1 or just simply -2.

Rewrite the equation with the perpendicular slope:

y = -2x - 6

Solve the inequality. Graph the solution set. 2r−9≤−6
Annette [7]

Hey there! :)

2r - 9 ≤ -6

To solve for r, we must move all variables to one side.

So, let's start out by adding 9 to both sides.

2r - 9 + 9 ≤ -6 + 9

Simplify.

2r ≤ 3

Divide both sides by 2.

2r ÷ r ≤ 3 ÷ 2

Simplify.

r ≤ 3/2

Simplify so that we don't have improper fractions.

r ≤ 1 1/2

Therefore, r is lesser than or equal to 1 1/2.

Using the process of elimination, we can see that the only answer choice that has r ≤ 1 1/2 in it is the THIRD answer choice.

~Hope I helped!~
