Answer:
1)
82.5 - <u>8</u><u>2</u><u>.</u><u>5</u> + 2x = 338.5 - <u>8</u><u>2</u><u>.</u><u>5</u>
<u>2</u>x = <u>2</u><u>5</u><u>6</u>
2)
2x ÷ <u>2</u> = 256 ÷ <u>2</u>
x = <u>1</u><u>2</u><u>8</u>
Step-by-step explanation:
1)
In order to get rid 82.5, you have to substract the same value on both side to get a 0 value.
2)
In order to find the value of x, you have to divide the value that is sticked with x which is 2. As you divide 2 by 2, you will get 1 as a single value of x so you have to divide 2 to both side too.
The percentage of the increase will be 25% when the number of students in the marching band increased from 100 to 125.
<h3>What is the percentage?</h3>
The Percentage is defined as representing any number with respect to the 100. It is denoted by the sign %.
It is given in the question that the number of students in the marching band increased from 100 to 125 so we need to find the percentage increase of the students.
The percentage increase of the students will be calculated as:-
% increase=[(125-100)÷(100)]x100
% increase=[(25)÷(100)]x100
% increase= [0.25x100]
% increase= 25%
Hence the percentage of the increase will be 25% when the number of students in the marching band increased from 100 to 125.

Answer: 2.7mm
Step-by-step explanation:
The formula for the circumference of a circle is given as 2πr. In thkw case, thw circumference is 17mm.
Therefore, 2πr = 17
2 × 3.14 × r = 17
6.28r = 17
r = 17/6.28
r = 2.7mm
Therefore the radius of the circle is 2.7mm
