<h3>Answer:  x = 3</h3>

To get that answer, we replace y with 8 and then isolate x.

5x-7 = y

5x-7 = 8

5x = 8+7

5x = 15

x = 15/5

x = 3

Which steps will generate an expression equivalent to 17(+5)
Bingel [31]

For this case we must indicate an expression equivalent to:

17 (x + 5)

By definition we have that the distributive property establishes that:

a (b + c) = ab + ac

Then, applying the property to the given expression we have:

17 (x + 5) = 17 * x + 17 * 5 = 17x + 85

Thus, an equivalent expression is:

17x + 85

ANswer:

17x + 85

What is the common difference of the arithmetic sequence 5, 8, 11, 14?
AnnZ [28]

Answer:

The common difference is 3

Step-by-step explanation:

we know that

In an <u>Arithmetic Sequence</u> the difference between one term and the next is a constant called the common difference

we have

5,8,11,14

so

a1=5

a2=8

a3=11

a4=14

a2-a1=8-5=3

a3-a2=11-8=3

a4-a3=14-11=3

therefore

The common difference is 3
