I think you're all right on the question expect for b because it's 6/8 and then simplify that I guess.
Answer:
x= 16
y= -13
Step-by-step explanation:
x+y=3
x-3y=-29
Eliminate x and subtract the equations
2y=-26
y= -13
Plug in y for first or second equation
x=16
Answer:
3/25
Step-by-step explanation:
Since it is stated that 12/25÷4
It can also be written as 12/25/4
Which means 12/25×1/4
So let's solve
3/25
The Reason why we get 3/25 is because 12 is being divided by 4
So the final answer to the given question is 3/25
Answer:
Not 100% but i think its A
Step-by-step explanation:
The area of the square will be 640 sq cm.
Step-by-step explanation:
Given,
Number of strip = 4
Length (l) of each strip = 40 cm
Width (b) of each strip = 4 cm
To find the area of the inner square.
Formula
The area of rectangle = l×b
If the area of a square is A, each side will be √A
Now,
Area of each strip = 40×4 sq cm = 160 sq cm
Area of 4 strips = 160×4 sq cm = 640 sq cm
Hence,
The area of the square will be 640 sq cm.
