Translation:הילדה אוכלת לימון אחד ושתי עגבניות.
This is the answer to your question from another thread:
A connecting vav (meaning 'and') is pronounced as ve (rarely va, vi) in all cases, and u in the following two cases:
Before a shva consonant. While this is hard to explain at this point in the course, think of it as two consecutive consonants, for example: ugvarim (וגברים) 'and men', ushmone (ושמונה) 'and eight'. There are cases where a shva consonant is not followed by another consonant, but ignore those for now.
Before the letters ב, ו, מ, פ, for example: uferot (ופרות) 'and fruits', uMoshe (ומשה) 'and Moses'.
