ikadub [295]

C-b=6
solve for c
c=b+6
substitute b+6 for c
b+c=10
b+(b+6)=10
2b=4
b=2
substitute that in to find C
c-b=6
c-2=6
c=8
a+b+c=18
a+2+8=18
a+10=18
a=8

so a=8, b=2, c=8

Which is more, 3 yards or 107 inches? 3 yards 107 inches neither; they are equal Submit

MakcuM [25]

We know, 1 yard=3 feet.

1 feet =12 inches.

Therefore, 1 yard in inches is,

$\begin{gathered} 1\text{ yard=3 f}eet\times\frac{12\text{ inches}}{1\text{ feet}} \\ =36\text{ inches} \end{gathered}$

Hence, 3 yards in inches is.,

$\begin{gathered} 3\text{ yards=3}\times36\text{ inches} \\ =108\text{ inches} \end{gathered}$

Therefore, 3 yards is greater than 107 inches.
