6. B- how Beth will skate safely
7. B- skip
Hope this helps! :)
The correct answer is B. Mama's plant
a=-.25+6.7t, s=.75+4.5t when Amir catches up a=s so:
-.25+6.7t=.75+4.5t (add .25 to both sides)
6.7t=1+4.5t (subtract 4.5t from both sides)
2.2t=1 (divide both sides by 2.2)
t=10/22 hr
t≈0.45 hr (to nearest hundredth)
the answer is 0.45
The first option Change all about to interested in, would be correct.
Hope this helped:)
