Answer:

47/3

Step-by-step explanation:

Multiply 3x+9 on both sides to get 7 = (3x+9)/8

Multiply 8 on both sides to get 56 = 3x+9

Subtract 9 on both sides to get 47=3x

Divide 3 on both sides to get 47/3

Answer:

47/3

Step-by-step explanation:

Solve for x

7/(3x+9) = 1/8

Multiply the numerator of the first f raction by the d enominator of the second fraction. Set this equal to the product of the denominator of the first fraction and the n umerator of the second fraction.

7 ⋅ 8 = (3x + 9) ⋅ 1

Solve the equation for x.

Rewrite the equation as (3x + 9) ⋅ 1 = 7 ⋅ 8.

(3x + 9) ⋅ 1 = 7 ⋅ 8

Multiply 3x + 9 by 1.

3x + 9 = 7 ⋅ 8

Multiply 7 by 8.

3x + 9 = 56

Move all terms not containing x to the right side of the equation.

Subtract 9 from both sides of the equation.

3x = 56 − 9

Subtract 9 from 56.

3x = 47

Divide each term by 3 and simplify.

Divide each term in 3x = 47 by 3.

3x/3 = 47/3

24 times 4 tons 2 pounds
Iteru [2.4K]
Ayy, so your question is kinda weirdly worded. But I think your asking what is 24 multiplied by 4 tons and 2 pounds.

Well, 2 pounds is equal to 0.00090718 tons.
There is a converter here: https://www.bing.com/search?q=pounds+to+tons&qs=AS&pq=pounds+to+tons&sc=8-14&sp=1&cvid=7BC591B75A8B4......

But now we have 0.00090718 tons as well as 4 tons. Add those together and you get 4.00090718. Now, multiply this by 24. You get: 96.02177232.

Hey there!

In order to answer this question, it's easiest to start with one of the money amounts and work your way to the other ones. Keep in mind that, no matter what, the amount of collective money won't exceed 1.50, meaning you can't have two 1 dollar bills, etc. When I wrote it out, I did it in this order:

1 = 1 dollar
0.5 = Half dollar
0.25 = Quarter

1 + 0.5 = 1.50
1 + 0.25 + 0.25 = 1.50
0.5 + 0.5 + 0.5 = 1.50
0.5 + 0.5 + 0.25 + 0.25 = 1.50
0.5 + (0.25*4) = 1.50
0.25*6 = 1.50

Since no other combinations add up to 1.50, your answer is 6. 

Hope this helped you out! :-)

There is no solution  for the first one

if you eliminate y   you get 2 equations
-13x - 13z = -25
-13x - 13x = -15    

- there is no solution to theses

a23  means the element in the second  row and the 3rd column

so its -5
