Kang Tae Moo thinks of a number. He adds 13 to the number. He multiples the result by 3. This gives the same result as if he multiplied the number by 9 and then subtracted 3. What number is Kang Tae Moo thinking of?

Answers

Answer 1

Answer:

7

Step-by-step explanation:

We can setup this equation as x representing his number.  (x+13) * 3 = 9x -3.

Now, we just need to solve for x.  

3(x+13)=9x-3

x+13=3x-1

14=2x

x=7

Answers

to find the number of yellow leaves you'll have to multiply number of red leaves she counted by 3.

8×3

=24

Linda counted 24 yellow leaves.

Linda counts 24 yellow leaves in total

How to determine the number of yellow leaves?

The number of red leaves is given as:

Red = 8

The statement 3 times as many yellow leaves as red leaves means that:

Yellow = Red * 3

So, we have:

Yellow = 8 * 3

Evaluate the product

Yellow = 24

C.

D.
David added 17 to both sides.

Answers

Answer:

Step by step I don't see the correct first step.

Step-by-step explanation:

Solve for x:

8 x - 13 = 2 x + 17

Hint: | Move terms with x to the left hand side.

Subtract 2 x from both sides:

(8 x - 2 x) - 13 = (2 x - 2 x) + 17

Hint: | Combine like terms in 8 x - 2 x.

8 x - 2 x = 6 x:

6 x - 13 = (2 x - 2 x) + 17

Hint: | Look for the difference of two identical terms.

2 x - 2 x = 0:

6 x - 13 = 17

Hint: | Isolate terms with x to the left hand side.

Add 13 to both sides:

6 x + (13 - 13) = 13 + 17

Hint: | Look for the difference of two identical terms.

13 - 13 = 0:

6 x = 17 + 13

Hint: | Evaluate 17 + 13.

17 + 13 = 30:

6 x = 30

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of 6 x = 30 by 6:

(6 x)/6 = 30/6

Hint: | Any nonzero number divided by itself is one.

6/6 = 1:

x = 30/6

Hint: | Reduce 30/6 to lowest terms. Start by finding the GCD of 30 and 6.

The gcd of 30 and 6 is 6, so 30/6 = (6×5)/(6×1) = 6/6×5 = 5:

Length = area / base

Answer:

the 1st, 2nd and 6th statements are true.

and probably the 3rd statement is true.

I am not sure about the 3rd statement, as I cannot read the original in your screenshot, and your transcribed description is probably not correct and contains typos.

but all you need is in the explanation below to decide, if the actual 3rd statement is true or not.

if "58 + 79 = 1268" actually means "5s + 7g = 1268" then it is true. otherwise it is false.

Step-by-step explanation:

g = number of general tickets sold

s = number of student tickets sold

so, in total

g + s = 234

tickets were sold.

and the revenue was

7g + 5s = $1,268

out of these 2 basic equating we get

g = 234 - s

and then

7(234 - s) + 5s = 1,268

1,638 - 7s + 5s = 1,268

-2s = -370

s = 185

g = 234 - s = 234 - 185 = 49

so, we know

185 student tickets were sold for 5×185 = $925

49 general tickets were sold for 7×49 = $343
