Illusion [34]

Answer:

See explanation

Step-by-step explanation:

Given two expressions

7(3y-5)-2(10+4y)

and

13y-55

Substitute y = 5 into each expression:

1.

7(3y-5)-2(10+4y)\\ \\=7(3\cdot 5-5)-2(10+4\cdot 5)\\ \\=7\cdot (15-5)-2\cdot (10+20)\\ \\=7\cdot 10-2\cdot 30\\ \\=70-60\\ \\=10

2.

13y-55\\ \\=13\cdot 5-55\\ \\=65-55\\ \\=10

As you can see the results are the same.

Answer:

  51

Step-by-step explanation:

The rule gives the sequence ...

  75, 69, 63, 57, 51, 45, ...

The 5th number in the sequence is 51.

__

<em>Alternate solution</em>

The equation for the general term of an arithmetic sequence is ...

  an = a1 +d(n -1) . . . . . for first term a1 and common difference d

Your sequence has first term 75 and common difference -6, so the equation is ...

  an = 75 -6(n -1)

Then for n=5, the term is ...

  a5 = 75 -6(5 -4) = 75 -24 = 51

The 5th term is 51.
