Answer:
B= 15 cm²
Step-by-step explanation:
The base of the triangular shaped wedge of cheese is a right-triangle.To find the area of a right-triangle you apply the formula for half base by height.
A=1/2*b*h = base area = B
In this case, assume the sides of the triangle given are; a=5 cm and b=6 cm, thus area will be 1/2*6*5 =15 cm²
B= 15 cm²

Answer:
Step-by-step explanation:
6x - 2y = -4
y= 3x + 2
We see that y = 3x + 2 so we can use that value of Y everytime we see i in the other equation.
6x - 2(3x +2) = -4
Now usually we'd we simply solve for X.
6x - 6x -4 = -4
This clearly does not work as we cannot get rid of X
Therefore, this system of equations has no solution we can find through substitution
To find the percentage, take the part (111) over the whole (300) then multiply the quotient by 100.
111 / 300 = 0.37
0.37 × 100 = 37%
