A square is a parallelogram, a rectangle, and a rhombus,
but it is not a pentagon.
Ok, so abc is a 3 digit number
easy
if we do
abc=x
then we have
750-x=x
add x to both sides
750=2x
divide both sides by 2
375=x
abc=375
check
750-375=375
correct
abc=375
0.abc=0.375
0.abc=0.375
that was fun

Answer:The area of the reduced backyard is 112.5 square feet
Step-by-step explanation:
The initial length of the backyard is 40.5 feet long.
The initial width of the backyard is 25 feet wide.
In order to install a pool, the yard needs to be reduced by a scale of 1/3. This means that the new length of the backyard is would be
40.5 × 1/3 = 40.5/3 feet lonng
The new width of the backyard would be
25 × 1/3 = 25/3 feet wide
The backyard is rectangular in shape. Area of a rectangle is length × width. The area of the reduced backyard becomes
40.5/3 × 25/3 = 1012.5/9 = 112.5 square feet
1.5x+6-3=4.5(x-2)
1.5x+6-3=4.5x-9
1.5x+3=4.5x-9
1.5x-4.5x+3=-9
1.5x-4.5x=-9-3
-3x=-9-3
-3=-12
X=4
