Answer:
A is the correct equation
Step-by-step explanation:
Write an out an equation using the information given. So:
8 + 5 + x - 2 = 14.5
<span>13 + x - 2 = 14.5 </span>
<span>11 + x = 14.5 </span>
<span>x = 3.50
This means that the answer is D.
Hope this helped :)</span>
Work backwards with pythagoras' theorem:
c^2=a^2+b^2
Here, a and b both equal to x. Therefore, you can write this as 8^2=2x^2. So 64=2x^2. Sqrt on both sides to give you 8=2x, hence x=4. However I must warn you that this working out may have a flaw, as I found that x actually equals to 5.66
Answer:
-2/3, -0.6, 0.2, 1/2, 5/8
Step-by-step explanation:
What you do is you have to make them into decimals.
-0.6 and 0.2 are already in decimals.
-2/3 as a decimal is -0.667
1/2 as a decimal is 0.5
5/8 as a decimal is 0.625
-2/3, -0.6, 0.2, 1/2, 5/8 is your answer.
