Answer:
240
Step-by-step explanation:
1 percent=10 dollars
10 percent=100 dollars
=120 dollars in one year
times 2 [2x]=
240
Check:
10 times 10=100 dollars
100+20=120
x2=
120+120 <em>or</em> 120 times 2=
240
Answer:
X is equal to 7
Step-by-step explanation:
Open parenthesis.
3/4x +63/4=21/2
take common denominator
3/4x=42/4-63/4
Solve
3/4x=-21/4
3x=21
x=7
%change=100(final-initial)/initial
In this case:
%change=100(3.18-2.56)/2.56
%change=100(0.62)/2.56
%change=62/2.56
%change=775/32%
%change=24.21875%
%change≈24% (to nearest whole percent)
Step-by-step explanation: Since the width and length are consecutive odd integers, call the width <em>x</em> and the length <em>x + 2</em>.
Now, it would be helpful to draw a picture of your rectangle
and label its parts to help you set up the equation.
Since the perimeter of the rectangle is 120 meters,
<em>x + x + (x + 2) + (x + 2) = 120</em>.
Simplifying from here we get 4x + 4 = 120.
Now subtract 4 from both sides to get 4x = 116.
Now divide both sides by 4 to get x = 29.
So the width of our rectangle is 29 meters
and the length, <em>x + 2</em>, is 31 meters,
Answer:
1. 13+18+13+14+13+16+14+21+13
= 145/9
=16.11
2. Range =145
3. Mode =13
4. Median =14
