Answer:
35ab = 48
Step-by-step explanation:
given
5a = 6 ( divide both sides by 5 )
a = [tex]\frac{6}{5}[/tex]
and
7b = 8 ( divide both sides by 7 )
b = [tex]\frac{8}{7}[/tex]
substitute these values for a and b into the expression and simplify
35ab
= 35 × [tex]\frac{6}{5}[/tex] × [tex]\frac{8}{7}[/tex] ( divide 35 and 5 by 5 )
= 7 × 6 × [tex]\frac{8}{7}[/tex]
= 42 × [tex]\frac{8}{7}[/tex] ( divide 42 and 7 by 7 )
= 6 × 8
= 48
