Remembering PEMDAS we solve like this
5•6=30 6÷2=3 30-3=27
27 is answer. it is easy, just replace the letter with the number and solve it
Answer:
13
Step-by-step explanation:
As x and y are perpendicular - we can use pythagoras.
So, The length of side x squared + The length of side y squared = The missing length squared.
12^2=144
5^2=25
144+25=169
sqrt169=13
Answer:
1kg = 1000g
400g = 0,4 kg
0,4 - 1
1 - n
multiply diagonally
0,4*n = 1
n=10/4=2,5
1:2,5 is correct answer
