Stuff:
4/8 or 1/2 of pie is left.
Mr. Vargas eats 1/4 of the whole pie.
8 slices * 1/4 = 8/4 = 2 slices.
Out of the 4 slices remaining, Mr. Vargas ate 2 slices.
That left 2 slices from the original 8 slices.
2/8 = 1/4
Answer: 1/4 of the pie remained.
Answer:
True, A linear equation determines a line in the xy-plane.
Step-by-step explanation:
A linear equation is in the form of Px + Qy = R where P , Q and R are constants.
Let us take an example 2x +3y = 6
When we plot the above equation in graph we get a line in xy plane.(as shown below) Since, there are two variables, x and y, then will it be possible, only on the xy plane.
It is also clear from the graph that linear equation shows the relation between x and y axis. Thus, it is true to say a linear equation determines a line in the xy-plane.
Answer:
An algebraic expression is an expression which consists of variables, coefficients, constants, and mathematical operators such as addition, subtraction, multiplication and division. Generally, if two things are the same, then it is called equivalent.

Answer:
x = 10.52 m
Step-by-step explanation:
Given that,
Length of a park = 90 m
Width of a park = 60 m
Area, A = 9000 m²
A uniform strip borders all four sides of the park for parking. We need to find the width of the strip. Let it is x. Now the area becomes,
(90+2x)(60+2x) = 9000

So, the width of the strip is equal to 10.52 m.
