Answer: a = 5

Step-by-step explanation:

      To solve, we will isolate the variable <em>a</em>.

Given:

2а + 20 = -3а - 5

Add 3a to both sides of the equation:

5а + 20 = - 5

Subtract 20 from both sides of the equation:

5а = 25

Divide both sides of the equation by 5:

a = 5

0.2y=0.5x+0.1 please solve with math thank you
Cerrena [4.2K]
<span>"Simplifying 0.2y = 0.5x + 0.1
 Reorder the terms: 0.2y = 0.1 + 0.5x Solving 0.2y = 0.1 + 0.5x Solving for variable 'y'.
 Move all terms containing y to the left, all other terms to the right.  
Divide each side by '0.2'. y = 0.5 + 2.5x Simplifying y = 0.5 + 2.5x"</span>

I have a 3 foot board that needs to be equally decided into 1/2 how many extra peices will I have
anygoal [31]

Answer:

No extra pieces.

Step-by-step explanation:

Given:

Total number of foot board = 3

Equally divided into =  1/2

Question asked:

How many extra pieces will I have = ?

Solution:

By dividing 3 by 1/2 we can find the extra pieces.

                                                                 = 3\div\frac{1}{2}

                                                                 = 3\times\frac{2}{1}

                                                                 = 6

Since, the remainder is zero, thus there is no any extra pieces I have.
