a. 7/50
b. 7/15
c. 3/8
d. 12/50

Answer 2

you just have to plug in \[\color{red} {3/10~~~~~~for~~~~x}\]\[\color{red} {and~~~~~4/5~~~~~~for~~~~y}\]

Answer 3

Is it C. 3/8 because (3/10)/(4/5) = 0.375 and 0.375 as a fraction is 3/8 ?

Answer 4

\[\frac{3}{10} \div \frac{4}{5} ~~~->~~~~~\frac{3}{10} \times \frac{5}{4} \]CORRECT!

Answer 5

okay, what is the solution of 2x + 5 = y

I thought it would be (-2, 1), but my choices are;
a. (5, 20)
b. (6, 12)
c. (3, 11)
d. (4, 14)
