A number (x) increased by 6 and then the sum is doubled

Answers

Answer 1

Answer:

The number 10 increased by 6 and then doubled equals 32.

To express the situation where a number (x) is increased by 6 and then the sum is doubled, we can write it as:

2(x + 6)

In this expression, (x + 6) represents the number increased by 6, and then multiplying the sum by 2 doubles the result.

For example, if the number x is 10, then the expression would be:

2(10 + 6) = 2(16) = 32

So, in this case, the number 10 increased by 6 and then doubled equals 32.

You use 6 gallons of water on 20 plants in your garden. At that rate, how much water will it take to water 30 plants?

Answers

9 because if you split the planta up into 10's, you would split the gallons into 3's. Thats 3 gallons per 10 plants

To do this, set up a proportion. The proportion would be 6/20=x/30. To do this, multiply 30 by 6. This gives you 180. Now you want to divide 180 by 20. This gives you 9. It would take 9 gallons of water to water 30 plants.

Michelle is building a rectangular landing strip for airplanes .She has material to cover 1/1,500 of a square mile. The landing strip must be 1/6 of a mile long. With the amount of material that has , what is the greatest possible width the land strip, in miles?

Answers

I think that the missing word here is:
"with the amount of the material that Michelle has"

Let's say that her landing strip is x miles long, then its area would be:

$(1)/(6) *x$

We also know how big it is:

$(1)/(6) *x= (1)/(1 500)$

now, let's multiply both sides by 6:
$(6)/(6) *x= (6)/(1 500)$
$1 *x= (3)/(750)$
$x= (1)/(250)$

So the answer is that it would be $x= (1)/(250)$ miles wide

o when n-6 the expression equals 1
-8; when n= 6 the expression equals -1
42-8n; when n = 6 the expression equals -6
8n-42; when n-6 the expression equals 6

Answers

Answer:

Step-by-step explanation:

8 less then the quotient of 42 and a number

a " quotient " is the result of division

(42 / n ) - 8.....when n = 6

(42/6) - 8 =

7 - 8 =

-1

so when n = 6, the expression = -1
