Answer:
Step-by-step explanation:
a^2+b^2=400
a^2=400-b^2
a=sqrt(400-b^2) & -sqrt(400-b^2)
-----------------------------------------------
b^2=400-a^2
b=sqrt(400-a^2) & -sqrt(400-a^2)
Answer:
4/5
Step-by-step explanation:
y is 5 times as big as x
When y is 4, divide it by 5 to find x
x = 4/5
Answer:
First equation is the right answer.
X÷3=0.6
1.8÷3=0.6
0.6=0.6
Hence proved
The answer would be:
3 + 3 + 3 + 3...
... If you mean what I'm thinking.
