Answer:
x(1+.05)
or 1.05x
Step-by-step explanation:
Answer:
50+0.4*50
Step-by-step explanation:
Because it has 140% of the RDA and the RDA is 50, that means it has 50 and 40% or 0.4 of 50. So the answer is 70 mg.
Answer:
I guess! Sorry, which answer are you talking about?
Step-by-step explanation:
Answer:
2 sqrt(3) = x
Step-by-step explanation:
We know that
sin theta = opp side / hypotenuse
sin 60 = x /4
Multiply each side by 4
4 sin 60 = x
We know
sin 60 = sqrt(3) /2
4 * sqrt(3) /2 = x
2 sqrt(3) = x
Y=2x
so what you do is sub 2x for y in the top equation
x^2+(2x)^2=5
x^2+4x^2=5
5x^2=5
divide both sides by 5
x^2=1
sqrt both sides
x=1 or -1
sub back
y=2x
y=2(-1)
y=-2
y=2(1)
y=2
the solutions are (1,2) and (-1,-2)
