Aligning three minipages with equations side by side

I’m running into an issue when trying to position three equations side by side. I’m using the minipage function but the problem is that whatever width I pick one of the eqautions is always slighly shifted up or down.

begin{minipage}[t]{0.25textwidth}
begin{equation}
    beta^2=1-M^2
end{equation}
end{minipage}
begin{minipage}[t]{0.35textwidth}
begin{equation}
    eta=frac{C_{l_{alpha}}}{2pibeta}
end{equation}
end{minipage}
begin{minipage}[t]{0.4textwidth}
begin{equation}
    F=1.07left(1+frac{d}{b}right)^2
end{equation}
end{minipage}

That’s the code I’m using.

any ideas, please, I’m in quite a rush :(((
