Just to remove ambiguities, the bar over the expression means it's repeating itself to infinity.
notice, the idea being, you multiply it by 10 at some power, so that you move the "recurring decimal" to the other side of the point, and then split it with a digit and "x".
now, you can plug that in your calculator, to check what you get.
Answer:
Tom weighs 70 pounds
Step-by-step explanation:
first, you have to set up your equation which would be, x + 3x = 280.
The x stands for Tom's weight and the 3x stands for three times Tom's weight for the dad. You would then add your like terms, then divide by 4 to get 70.
x + 3x = 280
4x = 280
280/4 = 70
x = 70
Hope this helps!
Answer: 3 and -3
Your welcome
If the diameter is given in a problem, area is computed as
A = (π/4) × D<span>2 where </span><span>π is equal to 3.14</span>
<span>If D (diameter) of one circular table is 6 ft its Area is 28 sq ft.</span>
If D of another circular is 8 ft its Area is 50 sq ft.
<span>The difference between the areas of the two tables is, therefore (50-28) or 22 sq. ft.</span>
Hi there! The answer is A) x = 3 or x = 6
Divide by 2.
Factor.
Use the rule AB = 0 gives A = 0 or B = 0
The answer is A) x = 3 or x = 6
