Hello! the answer is c
First of all let's eliminate the answers that do not make sense. For A. numbers are NOT irrational because they are a fraction. Numbers are also not irrational because they are a repeating number. C and D are both correct as fractions and terminating decimals are both rational numbers.
By using a certain formula you can convert repeating decimals to a fraction. But most people know that .3333333 is 1/3. This gives us 11 1/3 as our answer. So what does it match? It is not a terminating decimal. It repeats but can be written as a fraction. Therefore our answer is C) Rational, because it is a fraction.
I hope this helps!
E. t - 2t - 3t =32, t=8
A. 2x + 5 (x-1)= 9, X= 2 it's ok because
B. p - 3(p-5)= 10, p= 2.5 it's ok as well because
C. 4 y +3 y=28, y=4 also it's ok because
E. t - 2t - 3t =32, t=8 it's not ok because
a (-) is missing!
4 [ 2(6ft × 1.5ft) ÷ 2 ] + ( 3ft × 3ft )
= 4 [ 2(9) ÷ 2 ] + ( 3ft × 3ft )
= 4 [ 18 ÷ 2 ] + ( 3ft × 3ft )
= 4 ( 9 ) + ( 9 )
= 36 + 9
