Answer:
₹996
Step-by-step explanation:
Area painted = area of wall - area of wall posture
Area of a rectangle = length x breadth
= 10.5m x 8.5m = 89.25m^2
Area of a square
length x length
2.5m x 2.5m = 6.25m^2
Area painted = 89.25m^2 - 6.25m^2 = 83m^2
Total cost of area painted = 83m^2 x 12 = 996
Answer:
Total number of bracelets Brianna have are 12 .
Step-by-step explanation:
Let us assume that the total numbers of the bracelets be x .
As given
Brianna has 4 pink bracelets.
One third of all her bracelets are pink .
Than the equation becomes
Simplify the above
x = 4 × 3
x = 12
Therefore the total number of bracelets Brianna have are 12 .
f) 16 - p = 12 minus 12
4 - p = 0 plus p
p = 4
g) 18 - 2p = 6 divide by -2
-9 + p = -3 plus 9
p = 6
h) p x 2 + 4 = 9 divided by 2
p + 2 = 4.5 minus 2
p = 2.5
i) p x 4 - 3 = 1 plus 3
p x 4 = 4 divided by 4
p = 1

Answer:
Answers provided below
Step-by-step explanation:
From the simultaneous linear equation, we have the coefficient matrix as;
(3 4 5)
(2 -1 8)
(5 -2 7)
The x-matrix is Dx is given by;
(18 4 5)
(13 -1 8)
(20 -2 7)
Similarly, the y-matrix Dy is given by;
(3 18 5)
(2 13 8)
(5 -20 7)
Also,the z-matrix Dz is given by;
(3 4 18)
(2 -1 13)
(5 -2 -20)
Determinant of the coefficient matrix from online determinant calculator is;
D = 136
Determinant of the x-matrix from online determinant calculator is; Dx = 92
Determinant of the y-matrix from online determinant calculator is; Dy = 696
Determinant of the z-matrix from online determinant calculator is; Dz = 576
From crammers rule;
x = Dx/D = 92/136
y = Dy/D = 696/136
z = Dz/D = 576/136
