Solve the equation for a

Simplify the equation:

(a + -5) + a = 19

Reorder the terms:

(-5 + a) + a = 19

Remove the parenthesis around (-5 + a) :

-5 + a + a = 19

Combine like terms:

a + a = 2a

-5 + 2a = 19

Final equation:

-5 + 2a = 19

To solve for variable A:

You have to move all terms containing A to the left, all the other terms to the right.

Add '5' to each side of the equation.

-5 + 5 + 2a = 19 + 5

Combine like terms again:

-5 + 5 = 0

0 + 2a = 19 + 5

2a = 19 + 5

Combine like terms:

19 + 5 = 24

2a = 24

Finally divide each side by '2':

a = 12

Simplify:

a = 12

Answer: A=12

Salsk061 [2.6K]

Answer:

Each marker will be exactly <u>103</u> miles apart.

Step-by-step explanation:

It is given that Ian wants to run 412 miles and has set up 3 markers the same distance apart.

Between the start and end of run, the 3 separate markers will divide the 412-mile distance into 4 equal segments.

So each segment = 412/4 = 103 miles

Each marker will be exactly <u>103</u> miles apart.

Garne Problem med
Citrus2011 [14]

Total distance the rover need to travel ​is D = 1miles .

<u>Step-by-step explanation:</u>

We have , Garne Problem med   . A rover needs to travel mile to reach its destination  traveled mile. a rover needs to travel 5/8 mile to reach its destination it has already travel 3/8 miles . We need to find that  how much farther does the rover need to travel ​ , Let's do it step by step:

First , rover has already traveled 3/8 miles , Let total distance to be traveled by rover is D :

⇒ D = \frac{3}{8} + d , where d is distance left to cover .

Now, rover need to travel 5/8 miles more to reach destination :

⇒ D = \frac{3}{8} + d , where d is distance left to cover  , So d = \frac{5}{8}

⇒ D = \frac{3}{8} + d

⇒ D = \frac{3}{8} + \frac{5}{8}

⇒ D = \frac{3+5}{8}

⇒ D = \frac{8}{8}

⇒ D = 1miles

∴ Total distance the rover need to travel ​is D = 1miles .

notka56 [123]

Answer:

80%; 30%

Step-by-step explanation:

There is 5 blue marbles, 2 black marbles, and 3 red marbles. In other words, there is a total of 10 marbles.

There are only 2 black marbles and 8 marbles that are not black. Therefore, the probability of <em>not</em> drawing a black marble is 8/10 or 4/5 or 80%.

There are only 3 red marbles out of the 10 total marbles. Therefore, the probability of drawing a red marble is 3/10 or 30%.
