($30-$20)/$0.1 = number of texts needed

Why is the equation like this. Here is the explanation.

We first need to find the price difference between the two subscriptions, therefore we subtract the cheapest subscription price from the expensive.

$30-$20

We then divide that number by the price per text message and end up with the number of texts needed for the subscriptions to cost the same. (We add the parentheses because of the order of operations. We want to subtract first, therefore we need the parentheses)

($30-$20)/$0.1

Let's calculate the individual steps

$30-$20 = $10
$10/$0.1 = 100

The total number of messages they need to send for the subscriptions to cost the same is 100.

18(26) using distributive property and simplify
podryga [215]

Using distributive property and simplifying 18(26) we get 468

Step-by-step explanation:

We need to use distributive property and simplify: 18(26)

The distributive property stays that: a(b+c)=ab+ac

We can write 26 as 20+6

18(26)= 18(20+6)

Solving 18(20+6) using distributive property

18(20+6) =18*20+18*6

              = 360+108

              = 468

So, using distributive property and simplifying 18(26) we get 468

8 <br> 7<br> /<br> 8<br> + <br> 9 <br> 13<br> /<br> 16<br> what is this in a mixed number.
FinnZ [79.3K]

Answer:

18 and 11/16

Step-by-step explanation:

I converted the two numbers into improper fractions which leaves me with

71/8+157/16

I thenn made sure I had common denominators, which means I need to multiply the first number by 2/2 and I'm left with:

142/16+157/16

I can now add the 2 numbers together and I get:

299/16

now we just need to convert the number into a mixed number by dividing, and I am left with:

18 and 11/16
