8, 10, 12

A helpful equation:
x+x+1+x+2 = 30

Combine like terms
3x + 3 = 30

Subtract 3 from each side
3x = 27

Divide each side by to isolate x
x = 9

x = 9. However, 9 is not an even number. Let’s subtract 1 from 9 to get the first even number.

The first number is 8. The best two even numbers after 8 are 10 and 12.

8 + 10 + 12 = 30, thus this is the sequence.

Answer:

here:

you can make an equation

x + ( x + 2) + (x + 4) = 30

then by combining like items you get

3x + 6 = 30

then solve

3x = 30 - 6 ; then 3x = 24 , and x = 8

so the three numbers are 8 ; 10 and 12.

Answer:

Yes, x and y have a proportional relationship.  

Step-by-step explanation:

A proportional relationship means that, when comparing two quanities, that they are both changing at a constant (same) amount.  When looking at a table to compare quantities, you can see that the pounds of tomatoes 'x' is increasing by one (1) each time.  If you look at the amount spent in dollars 'y', you can see that for each pound (x), the cost is increasing by $4.  So, since for every pound of tomatoes that is purchased increases by $4, then their relationship is proportional.

Answer:

4p^{2} +6p-8

Step-by-step explanation:

Remember these rules for addition, substraction, multiplication or division:

Addition

+ + = +

- - = -

Big + number - =  +

Big -number + =  -

Substraction

change the sign!

And follow the rules for addition

Multiplication or division

+ + = +

- - = +

+ - = -

Now for the exercise

2p^{2} + 3p - 4

<u>- (- 2p^{2} -3p +4)</u>

<u />

Change the signal

2p^{2} + 3p - 4

<u>(+2p^{2}+3p-4)</u>

4p^{2} + 6p -8
