Answer:

20 ≥ 9 + (8 -7)·6
20 ≥ 1 + (2 -3)·4
20 ≥ 8 +(3 -5)·4

Step-by-step explanation:

You mainly need to make sure that the product has a value less than 20. That's not hard to do, since the difference can't be more than 9, and can be negative.

Pick some digits to put into the expression and see what the value is. Then make any adjustments you might need to make to reduce the sum. If you put 0 in the rightmost box, the other digits can be anything. (They just have to be different.)

To rent a jet ski at Hayden’s cost is $25 plus $3 per hour. At Austin’s, it costs $5 plus $8 per hour. At how many hours will th

Katen [24]

<u>At Hayden's:</u>

$(25+3)= \ 28+3 \ (2nd \ hour)=31+3 \ (3rd \ hour)=34+3 . . . \swarrow\swarrow \\ \ \Longrightarrow \Longrightarrow \Longrightarrow \Longrightarrow \Longrightarrow \Longrightarrow \Longrightarrow \Longrightarrow \Longrightarrow \Longrightarrow \Longrightarrow \boxed{34+3=37}= \ (4rth \ Hour)$

<u>At Austins:</u>

$(5+8)= \ (first \ hour) = 13+8= \ 21 = (2nd \ hour) \ 21+8=29= \ \swarrow \\ \longrightarrow \ 29=(3rd \ hour)=\boxed{ 29+8= (37)= \ ((Forth \ hour))}$

As we can see in both results, it would take them (4 hours) for the prices to be equaled.

How would you teach something you have learned this year in Math to someone younger than you? Write more than 5 sentences

rewona [7]

Answer:

ok here ya go

Step-by-step explanation:

A way that I would teach someone something that I learned in math this year to someone else is simple. I would start by writing everything out so that they have a visual of what I am teaching them. I would also use a visual of a real world situation so that it relates to something they would understand. Teaching someone younger than you means they probably will not understand as easy as you understood it so, I would be very slow and make sure if they are confused to help them. I would also make sure not to be too bossy, understanding that they may not understand and that is ok.

Add or subtract as indicated 5/x-2 - 3/x-2

algol [13]

Option a: $\frac{2}{x-2}$ is the right answer

Step-by-step explanation:

The given expression is:

$\frac{5}{x-2} - \frac{3}{x-2}$

As the denominators of both terms are same, the LCM will be x-2

$\frac{5-3}{x-2}$

Subtracting

$\frac{2}{x-2}$

Hence,
