If 21 is added to a number the result is 40 less than twice the number what is the number?
Karolina [17]
If 21 is added to (+ 21) a number (x) the result (=) is 40 less than (- 40) twice the number (2x)

x + 21 = 2x - 40   Add 40 to both sides
x + 61 = 2x           Subtract x from both sides
      61 = x             Switch the sides to make it easier to read
       x = 61

Geometry! Please help!
kogti [31]
Angle ADB= 40 degrees.
The triangle ADB is equal to 180 degrees. Subtract 180-105=75
Since vertical angles are always congruent angle ABD= 35 degrees.
So 75-35=40.

Can you choose a starting point so that the first 5 numbers in your sequence are all positive? Explain your reasoning.
marin [14]

Answer:

Take the starting point as the first natural number that is 1.

Step-by-step explanation:

To find: a starting point so that the first 5 numbers in the sequence are all positive

Solution:

Natural numbers are numbers that are used for counting.

Natural numbers are basically positive integers.

Take the starting point as the first natural number that is 1.

The next point as 2.

The next point as 3.

The next point as 4.

The next point as 5.

So, the sequence becomes 1,2,3,4,5,... so that the first 5 numbers in the sequence are positive.
