Answer:

The second step.

Step-by-step explanation:

Alan didnt cross multiply. He multiplied straight across.

The correct way is:

x over 200 = 8 over 25

200(8) = 1600

25(x) = 25x

1600/25 = 64

25x/25 = x

So, the correct answer is x = 64

<em>Hope this helps</em>

Step 2 was his error.

The following problem is solved by Alan:

\frac{x}{200} =\frac{8}{25}

In solving for x, you have to cross multiply between the numbers.

In that case, step 2 would look like this:

(25)(x) = (8)(200)

NOT THIS:

(8)(x) = (25)(200)

Now continue all the way.

25x = 1600

x = 1600 ÷ 25

x = 64

2. What is the value of x?
Goshia [24]

Answer:

x = 5

Step-by-step explanation:

The total degrees in a 4 sided polygon is 360°

360° = 51° + 51° + 2(28x - 11°)

56x - 22° + 51° + 51° = 360°

56x = 280°

x = 5

A cash register contains only five dollar and ten dollar bills. It contains three times as many five dollar bills as ten dollar
Finger [1]

Answer:

38

Step-by-step explanation:

Let x be the number of ten dollar

Number of five dollar=3x

Total amount of money in the cash register=$950

We have to find the number of ten dollar bill in the cash register.

According to question

5\times (3x)+10x=950

15x+10x=950

25x=950

x=\frac{950}{25}

x=38

Hence, number of  ten dollar bills  in the cash register=38
