Here is a diagram and its corresponding equation. Find the solution to the equation.
fomenos

Answer:

The solution to the equation is:

  • <u>x = 2.5</u> or <u>x = 5/2</u>

Step-by-step explanation:

To find the solution to the equation, you only must operate the equation until you clear the x variable, with the next steps:

  • Equation: 4(x+7) = 38

And we solve:

  • 4x + 28 = 38 (we multiply 4 by x and 7)
  • 4x = 38 - 28 (we pass the +28 to subtract to the right side of the equality and operate)
  • x = 10 / 4 (we pass the 4 that is multiplying to divide to the right side of the equality)
  • <u>x = 2.5</u> (we divide)

As you can see, <u><em>the solution of the equation is </em></u><u><em>x = 2.5</em></u><u><em> or </em></u><u><em>x = 5/2</em></u>

How many 2-digit numbers are among the terms of the arithmetic sequence 2, 7, 12, 17, ...?
Snowcat [4.5K]

Answer:

20

Step-by-step explanation:

It seems like the rule of this sequence is to add 5 (since 2 + 5 = 7 and 7 + 5 = 12). We already are given that we have 2 2-digit numbers (12 and 17) so let's see if there are any more. The sequence continues to 22, 27, 32, 37, 42, 47, ..., 92, 97. We need to count how many numbers are in the list 12, 17 ... 92, 97. To do this, let's add 3 to every term in the list to get 15, 20, ... 95, 100. Since the list is now full of multiples of 5 we can divide the list by 5 to get 3, 4, ... 19, 20 and then subtract 2 to get 1, 2, ... 17, 18 which means that there are 18 2-digit numbers.
