3/2 (x-2) = 15

1. Multiply 3/2 by (x-2).
3(x-2)/2 = 15 :

3x-6/7 = 15

2. Multiply 7 by both sides and canceling out the denominator on the left side.
7 (3x-6)/7 = 7(15):

3x-6 = 105

3. Subtract six from both sides.
3x-6 +6 = 105 + 6:

3x = 111

4. Divide 3 into both sides.
3x/3 = 111/3

X = 37.


Check:

1. Fill in x with your final answer.
3/7 (37-2) = 15:

3/7 (35) = 15

2. Multiply 3/7 by 35.
3/7(35) = 15:

3 (5) = 15

15 = 15

3/7 (x - 2) = 15     multiply both sides by 7/3

x - 2 = 35     add 2 to both sides

x = 37

The corporate team-building event will cost $14 if it has 7 attendees. If there are 9
kobusy [5.1K]

Answer: for 9 attendees it would cost $18

Step-by-step explanation: First you have to find the unit rate. So for every 7 attendees it costs $14, divide them both by the GCF which is 7. 14÷7=2

7÷7=1

So for every 1 attendee it is $2.

Now to figure out how much it would cost for 9 attendees, figure out what you have to do to 1 to get 9. Multiply it by 9.

And whatever you do to one number you have to do for the other. So $2 • 9 = $18

So for every 9 attendees it costs $18.

HELP! 20 POINTS
guajiro [1.7K]
Work problems are solved by first figuring out how much of the job they can do  in each hour. Shawn can do 1/4 of the job in an hour and Ellie can do 1/6 of the job in an hour. 1/6+1/4=2/12+3/12=5/12. This means that they can do 5/12 of the job an hour. This means that together they can do the job in 2 2/5 hours. The foreman is obviously wrong because first of all Shawn can do it alone in 4 hours, so with Ellie he will do it faster, and second of all 2 2/5<5. Hope this helped!

Find the inverse of y=100-x^2
AnnyKZ [126]

Answer:

The inverse  is ±sqrt(100-x)

Step-by-step explanation:

To find the inverse, exchange x and y

x = 100 -y^2

Solve for y

Subtract 100 from each side

x - 100 = -y^2

Divide by -1

-x +100 = y^2

Take the square root of each side

±sqrt(100-x) = sqrt(y^2)

±sqrt(100-x) =y

The inverse  is ±sqrt(100-x)
