\\ \rm\Rrightarrow 5-3(2a+1)=-4+10

\\ \rm\Rrightarrow 5-6a-3=6

\\ \rm\Rrightarrow -6a+2=6

\\ \rm\Rrightarrow -6a=6-2

\\ \rm\Rrightarrow -6a=4

\\ \rm\Rrightarrow a=\dfrac{4}{-6}

\\ \rm\Rrightarrow a=\dfrac{2}{-3}

Now

\\ \rm\Rrightarrow a+2

\\ \rm\Rrightarrow \dfrac{2}{-3}+2

\\ \rm\Rrightarrow \dfrac{2-6}{-3}

\\ \rm\Rrightarrow \dfrac{-4}{-3}

\\ \rm\Rrightarrow \dfrac{4}{3}

Answer:

7/3

Step-by-step explanation:

5 - 3(2a+1) = -4 + 10

=> 5 - 6a + 3 = 6

=> 5 - 6 + 3 = 6a

=> 2 = 6a

=> 6a = 2

=> a = 2/6

=> a = 1/3

a + 2

1/3 + 2

=> 1/3 + 6/3

=> 7/3

Answer:

The answer is about 32,000.

Step-by-step explanation:

If you multiply 3.2 by 10, for 10 years, you get 32 percent. From there, if you multiply 25,000 by 0.32, you get 8000. If you add 25,000 to 8000, you get about 32,000.

291.87 irrational or rational
aliina [53]
291.87 is rational since the last (decimal) numbers aren't repeating.
If it was repeating (291.877777...) it would be irrational.
