Answer:
X=5.66 or 5.65685424949
Y=4
Step-by-step explanation:
Since this is a 45,45,90 triangle, the y is also 4.
Then the x is y^2+4^2.
That means that it is 16+16=32
Now you have to square 32 which gives you 5.66
Answer:
David made $18
Step-by-step explanation:
Leslie made $10. This means that you take 46-10=36
Chen-Chen made twice as much as David so 36/2=18 So Chen made $9.
David- 36-18= 18 So, David made 18 dollars.
From eq1 ,
2x = 13-3y
x = 6.5-1.5y (eq 3)
sub eq 3 into eq2,
4(6.5-1.5y)-y=-2
26-6y-y=-2
-6y-y=-2-26
-7y=-28
7y=28
y=4 ( eq 4 )
sub eq4 into eq3 ,
x=6.5-1.5(4)
x=6.5-6
x=0.5
