Does anyone know how to do #11 ? i need your again : (

Step-by-step explanation:

Four consecutive counting numbers would look like this

x

x + 1

x + 2

x + 3

Do you see that these numbers are 1 larger than the one before it. So if x is 20 the numbers would be 20 21 22 23

Now take the 4 general numbers and add them

x + x + 1 + x+2 + x + 3

4x + 6

Two will go into 4x to give 4x/2 = 2x

Two will go into 6 to give 6/2 = 3

Always happens. There are no exceptions. Try x = 20 again

20 + 21 + 22 + 23 = 86

Can this number be divided by 2? Yes it can 86/2 = 43

the correct answer would be:

220 centimeters

to get this you can use the pythagorean theorem

hope this

step-by-step explanation:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
