It means, "I have to eat." By the way, you can drop the Yo from your sentence because in Spanish, the yo is understood by the conjugation of the verb; there's only one person in the conjugation who is tengo. So you can get away with just saying, "Tengo que comer," and still be perfectly understood. You'll sound much more sophisticated.
Yo tengo que bañarme. It means, "I have to bathe (myself)."
It means, "I have to have..." It is possible to omit the "yo" (and not lose any of the meaning) because it is understood in the conjugated verb "tengo."
I, that I do have
"Yo tengo que estudiar" translates to "I have to study" in English.
i have to study now
"I have to draw in art class."
The syntax here is out of order. Realmente tengo que trabajar mañana. This means "Actually I have to work tomorrow". The "Yo" is not necessary with a conjugated verb.
the closest answer I can give you is 'I have', because I know that 'yo tengo' means i have
yo tengo a todos los que necesito
it means: actually, I have to work tomorrow.
I have sisters
I have of you.
I have it.
"I have flowers."
Yo tango = I dance the tango Yo tengo = I have
