Answer:
Option A: The answer should be 10% of 6 is the correct answer.
Step-by-step explanation:
Given that:
6 students play trumpet. As they represent 10% of the total students.
Let,
x represent the number of students in the band.
10% of x = 6
By solving this, we will get the value for number of students in the band.
As x will be our answer,
The choices B, C and D are correct in the given scenario.
However,
10% of 6 cannot be the solution to the problem.
Hence,
Option A: The answer should be 10% of 6 is the correct answer.
Answer:
<em>The perimeter of the rhombus is 20 cm</em>
Step-by-step explanation:
<u>Perimeter of a Rhombus</u>
Given the lengths of the two diagonals of a rhombus, let's call them a and b, the perimeter of the rhombus is given by:
The values of the diagonals provided by the question are a=6 cm, b=8 cm, thus the perimeter is:
The perimeter of the rhombus is 20 cm
I’m also struggling with the exact same type of problem too bad no one is willing to help me :((
Answer:
(10, -5)
Step-by-step explanation:
Given system of equations is,
0.6x - 0.3y = 7.5
Divide this equation by 0.3
2x - y = 25 -------(1)
0.4x + 0.2y = 3
2x + y = 15 -------(2)
Now we subtract equation (2) from equation (1),
(2x - y) - (2x + y) = 25 - 15
-2y = 10
y = -5
From equation (1),
2x - (-5) = 25
2x + 5 = 25
2x = 20
x = 10
Therefore, (10, -5) will be the solution of the system of equations.
