Hi there!

Let's replace "a number" by "x":

- two times x = 2x

- decreased by 3 = -3


Here's what the equation should look like:

2x - 3 = 11


Now that you have written down your equation, all you have to do now is solve it for "x" by isolating it :

2x - 3 = 11

Add 3 on each side of the equation

2x = 14

Divide each side of the equation by 2

x = 7


Your answer is: The number is 7.


There you go! I really hope this helped, if there's anything just let me know! :)

-k+3k combine like terms to create an equivalent expression​
Nimfa-mama [501]

Answer:

2k

Step-by-step explanation:

3k and -k are both like terms, so you can combine them. Adding opposite signs works in the same way as subtraction, so you can rewrite the expression as 3k-k, which is 2k.

Create a word problem using 30+2d as the answer
Tanzania [10]

Answer:

Sonya pays a flat fee of $30 for her phone bill and pays $2 per gigabyte she uses per month. Put Sonya's bill as an equation with <em>d</em> being how many gigabytes she uses per month.

Step-by-step explanation:

We get the flat fee of $30 from "30 + 2d" and the $2 per gigabyte from "30 + 2d" and since we want to find out Sonya's total bill, that's where the + in "30 + 2d" comes from. We want the variable to be <em>d</em> therefore <em>d</em> is how many gigabytes she uses per month.
