Remember that to solve an equation we need to isolate the variable in one side. To do it we can perform any mathematical operations we want as long as we perform the operations to both sides of the equation.

Let's solve our equation step by step

Step 1. Subtract $2x$ from both sides of the equation

$2x-8=5x+3$

$2x-2x-8=5x-2x+3$

$-8=3x+3$

Step 2. Subtract 3 from both sides of the equation

$-8-3=3x+3-3$

$-11=3x$

Step 3. Divide both sides of the equation by $3$

$-11=3x$

$\frac{-11}{3} =\frac{3x}{3}$

$-\frac{11}{3} =x$

$x=-\frac{11}{3}$

We can conclude that the next step is: subtract 3 from both sides of the equation.

In the following sequence of numbers each number has one more "1" than the preceding number: 1, 11, 111, 1111, 11111, ... . What

STatiana [176]

Answer: 2

Step-by-step explanation:

we have the sequence 1, 11, 111, 1111 and so on.

We can write this sequence as:

A0 = 1

An = A(n -1) + 10^n.

such that:

A1 = A0 + 10^1 = 1 + 10 = 11.

A2 = 11 + 10^2 = 11 + 100 = 111.

and we want to find the tens digit of the sum of the first 30 terms.

ok, in the 30 terms, in the units digit we have a 1, so we have:

30*1 = 30

we leave the zero and the 3 goes to the tens place.

For the tens place. the first term does not aport nothing, and the other 29 terms aport a 1, so we have:

tens = 3 + 29*1 = 32

then we leave a 2 here and pass a 3 to the hundreds place.

But we already answered the question, the tens digit in the sum of the first 30 numbers of the sequence is 2.
