:salam2: the equation is not well given because i don't have that key so don't worry,anyway here's the solution
x=-v7 or x=v7
v as square root
this equation shows 71.1% of water(sea) and 28.8 of land which explains the global warming,i guess.
:salam2:brother this's what i got as solution tell me if it's not correct insallah.X=5
how about X+3y=12...........equation 1
4X+6y=40...........equation 2
Solve the equations simultaneously and find the values of X and y
Sa'ad from Nigeria who is a Senior High School 3 student
how about this
0.2x+y=18 equation 1
x-1.2y=2.5 equation 2
Jack and Jill have two children. The probability that the first child is a girl, is 50%. The probability that the second child is a girl, is also 50%. Jack and Jill tell you that they have a daughter.
What is the probability that their other child is also a girl?
