You start by taking the 2.5 over to the other side. This is a positive number so when you take it over it will become a negative.
2.5-0.25x = -3
-0.25x =-3-2.5
-0.25x=-5.5
now -0.25 is being multiplied to x, when you take it over to the other side, it becomes divide.
-0.25x = -5.5
x = -5.5/-0.25
x = 22
5/10 would be 1/5
8/100 would be 2/25
Answer:
b=-1
Step-by-step explanation:
7b-2/5=6b-7/5
7b+1=6b
-b=1
b=-1

<h3>What is a quadrilateral?</h3>
A quadrilateral is a plane shape with four sides and four angles.
The above figure is made up of two quadrilateral; a square and a trapezium.
Analysis:
Area of park = area of square + area of trapezium
Area of park = 1/2(a + b)h + s x s
where a = length of smaller parallel side of the trapezium = 40m
b = length of the larger parallel side = 48m
h = height of trapezium = 35m
s = length of side of square = 10m
Area of park = 1/2(40 + 48)x35 + 10 x 10 = 1640 square meters
In conclusion, the area of the park is 1640 square meters
