Answer:
after 2 hours, they will have the same fee.
they will have been payed 11$
Step-by-step explanation:
if you say h = hours of tutoring,
Rakim charges 7 + 2h
Joan charges 3 + 4h
since you want them to be the same, you can write the following equation:
7 + 2h = 3 + 4h
<em>subtract 2h from each side</em>
7 = 3 + 2h
<em>subtract 3 from each side</em>
4 = 2h
divide both sides by 2.
h = 2
after 2 hours, they will have the same fee.
they will have been payed 11$
"they will have been payed" ah yes the grammar.

Answer:
777592000
Step-by-step explanation:
6 times 10 = 60 to the power of 5 = 60x60x60x60x60 = 777600000
