Answer: kindly check explanation
Step-by-step explanation:
Given that:
Area of rectangle = 120 cm²
Assume ; Length and width are whole numbers
Possible dimension of the rectangle will be :
Area of a rectangle = Length × width
Area = 120cm²
Possible dimensions :
80cm by 1 cm
40cm by 2cm
20cm by 4cm
10cm by 8cm
5cm by 16cm
Possibility which gives the smallest perimeter :
Dimension = 10cm by 8cm
Perimeter of Rectangle = 2(length + width)
Perimeter of Rectangle :
= 2(10 + 8)cm
= 2(18)cm
= 36cm
Step 1: multiple the second equation by 2 so that you get -1/4 for the coefficient of y, the same as in equation 1
equation 2 multiply by 2: 1/4 x - 1/4 y=38 ..........name this equation 3
subtract equation 1 from equation 3: (1/4 x -1/2 x)=38-10
-1/4 x = 28
x=-112
plug in x=-112 in any of the equation, you will get y=-264
so the answer is A
namely, how many times does 3/4 go into 3½? Let's firstly convert the mixed fraction to improper fraction.
