Answer:

The answer is 2.

Step-by-step explanation:

Remeber to always use PEMDAS.

1. (3 + 5) / x = 4 - We do the addition in the parenthesis first.

2. 8 / x = 4 - We now want to find what x means, to do this we divide the answers by the number we already have.

3. 8 / 4 = 2 - Now we can do the initial equation with the number we found to test it.

4. 8 / 2 = 4 - Simple as that :)

What is (1.7x10^4)x(8.5x10^-2) in standard form
Temka [501]

Answer:

1.445 × 10³

Step-by-step explanation:

Standard form is a way of writing a small number or a large number easily.

We should give the final answer in standard form.

1) (1.7 × 10⁴) × (8.5 × 10⁻²)

We enter this directly into the calculator to obtain a solution.

= 1445

We write this in standard form we have :

1.445 × 10³

masya89 [10]

Answer:

16 ride tickets.

Step-by-step explanation:

The original entry fee is $4 so you can subtract that from 12. Now you have $8. So you would double 8 since $0.50 is half of $1. 8x2 is 16.

So if a video that is 15:34 how long is it when 2 times speed
rusak2 [61]

Answer:

7:47

Step-by-step explanation:

Here are two ways of solving this:

The video will be half the time of 15:34, so you need to divide the time 15:34 by 2.

Method 1)

Use the tip. The video is 15 minutes and 34 seconds long.

Convert minutes to seconds: 15 * 60 = 900

Add 34 seconds to the 15 minutes: 900 seconds + 34 seconds = 934 seconds

The video is 934 seconds long.

Divide the total seconds by 2: 934/2 = 467

467 seconds = 420 seconds + 47 seconds = 7 minutes and 47 seconds

Answer: 7:47

Method 2)

Divide the minutes by 2 and divide the seconds by 2.

15 minutes and 34 seconds.

Divide minutes by 2: 15/2 = 7.5

Divide seconds by 2: 34/2 = 17

Now we need to add 7.5 minutes and 34 seconds.

0.5 minutes is half a minute, so it's 30 seconds.

7.5 minutes + 17 seconds =

= 7 minutes + 0.5 minute + 17 seconds

= 7 minutes + 30 seconds + 17 seconds

= 7 minutes + 47 seconds

= 7:47

Answer: 7:47
