Here, we are trying to solve for a:

\dfrac{a}{5} + 8 \leq 13


By using reverse operations on the left side of the problem, we can solve for a:

\dfrac{a}{5} + 8 \leq 13

\dfrac{a}{5} \leq 5

a \leq 25


Our answer is \boxed{a \leq 25}.

kow [346]

Answer:

10.5 miles.

Step-by-step explanation:

If she walks 7/10 of a mile each morning, and 1, 4/10 of a mile each day, Belle walks a total of 2 1/10 of a mile each day (2.1) miles each day)

We can just multiply the amount of miles per day by 5, (2.1 x 5) and we get 10.5 miles total.

Help, i know the answer but i don’t know how to do the work
Diano4ka-milaya [45]

Answer:

C

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

Simplifying each radical before combining them.

\sqrt{45t}

= \sqrt{9(5t)}

= \sqrt{9} × \sqrt{5t} = 3\sqrt{5t}

-----------------------------------------------------------------------------

\sqrt{125t}

= \sqrt{25(5t)}

= \sqrt{25} × \sqrt{5t} = 5\sqrt{5t}

---------------------------------------------------------------------------

Hence

2(3\sqrt{5t}) - 3(5\sqrt{5t}

= 6\sqrt{5t} - 15\sqrt{5t}

= - 9\sqrt{5t} → C

What is the value of x?
nexus9112 [7]

Answer:

x = 54

Step-by-step explanation:

The two angles are across a vertex and are therefore equal. Set the two angles equal and solve for x:

2x+2 = 3x - 52

     2 = x - 52

    54 = x
