2(3x + 4) / 2(2x + 2)
Cancel the factored 2s
3x + 4 / 2x + 2
You may need to further factor the denominator, depending on the teacher.
3x + 4 / 2(x + 1)
Answer:
D. 264yards
Step-by-step explanation:
If John swam halfway across a circular pond (radius) and he has gone 132 yds, then the radius of the circular pond is 132yards.
Diameter of the pond = 2×radius of the pond
Diameter of the pond = 2×132
Diameter of the pond = 264yards
Answer:
$.75
Step-by-step explanation:
9 ÷ 12 = 0.75
.75 × 12 = 9
Answer= 6.5y+12
distribute the 5 in the parentheses:
(-6y-3) + (15+12.5y)
(you can take away the parentheses after this step)
then add like terms together.
12.5y + (-6y) = 6.5y
15 + (-3) = 12
make it one expression.
6.5y + 12
To compare these numbers, you must first put them into one format. Since you have mixed numbers, you may have to find and use the LCD.
-2.5, 1/5, 10, -12/4, 18/5, 10 could be simplified somewhat immediately:
-2.5, 1/5, 10, -3, (3 3/5) This set of numbers is simple enough so that you could rearrange them in ascending order mentally:
-3, -2.5, 1/5, (3 3/5), 10
In this case the number of elements in this set is odd, so all you have to do is to select the MIDDLE element: 1/5.
The median is 1/5.
You MUST learn this procedure (arranging the set elements in ascending order and selecting the middle element) so that you can apply it yourself.
