The first one you have
=
. To solve this you would multiply both sides by 3.
=x
Then simplify by dividing the numerator and denominator by 3.
=x (or in a mixed fraction 1
)
The second one you have
=
. To solve this you would multiply both sides by x.
x=3
Now you would divide both sides by
.
x=
You now then multiply 3 by 24 and then divide by 7.

x=
(in a mixed fraction would be 10
)
Answer:

Step-by-step explanation:

New dimensions


The new area of the rectangle

Percentage change is given by

The percentage by which the area of the rectangle increases is
.
Answer:
area of sector= teete ×πr²
360
<u>4</u><u>0</u><u>°</u>×<u>2</u><u>2</u>×2×2
360 7

2520
<u>3</u><u>5</u><u>2</u><u>0</u>
2520
=1.397°
15 times .25 or 1/4
(1lbs=4 kids, 15 divided by 4= 3.75)
6.25 divided by .5 is over 12
so 12 adults
X = 2/3 + 5/6 + 4/6 + 5/6 = 9/6 = 3/2
