If 21 is added to a number, the result is 41 less than twice the number. Find the number.

Answer: 62

Step-by-step explanation: Set up your equation

  1. 21+x=2x-41 because the number (x) that 21 is added to is 41 <em>less than</em> (so subtraction) <em>twice </em>(so multiply the number x by 2) the number (x).
  2. Get the x's on one side by subtracting the single x
  3. 21=x-41
  4. Now add 41 to both sides to completely isolate x
  5. 62=x
  6. So, your answer is x=62. The number is 62.

Check your work. 62+21=83. 2(62)= 124. 124-41=83. Both equations equal 83, so the solution is correct.

Allisa [31]

Answer:

The area of the figure is 28 units².

Step-by-step explanation:

Find the area of the full rectangle, ignoring the triangle.

a = lw \\ a = 4 \times 8 = 32

Then, find the area of the triangle:

a =  \frac{bh}{2}  \\ a =  \frac{2 \times 4}{2}  \\ a = 4

Finally, subtract:

32 - 4 = 28
