Shalom guys!

Trying to conjugate verbs, and got several consecutive shva in the verbs. Could you tell me how to pronounce these forms?

חשב in זמן גתיד


היא תַחְשְבִי – ta.ch.sh.vi? ta.che.sh.vi? or ta.ch.she.vi?

אתם תַחְשְבוּ – tachshvu? tacheshvu? or tachshevu?

הם יַחְשְבוּ – yachshvu? yacheshvu? or yachshevu?



Would be very grateful if you explain the rule of pronunciation (if there any).

Toda raba!
