Answer:Simplifying

a = 1 + 0.3333333333b + 1.666666667c

Step-by-step explanation:

Simplifying

3a + -1b + -5c = 3

Solving

3a + -1b + -5c = 3

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add 'b' to each side of the equation.

3a + -1b + b + -5c = 3 + b

Combine like terms: -1b + b = 0

3a + 0 + -5c = 3 + b

3a + -5c = 3 + b

Add '5c' to each side of the equation.

3a + -5c + 5c = 3 + b + 5c

Combine like terms: -5c + 5c = 0

3a + 0 = 3 + b + 5c

3a = 3 + b + 5c

Divide each side by '3'.

a = 1 + 0.3333333333b + 1.666666667c

Simplifying

a = 1 + 0.3333333333b + 1.666666667c

What is another way to write the expression t. (14--5) ?

melomori [17]

Answer: Second option.

Step-by-step explanation:

It is important to remember the Distributive Property in order to solve this exercise.

The Distributive property states that:

$a(b+c)=ab+ac\\\\\\a(b-c)=ab-ac$

In this case you have the following expression provided in the exercise:

$t(14-5)$

Then, in order to write this expression in another way, you can apply the Distributive property. Multiply each number inside the parentheses by "t".

Applying this procedure, you get:

$t(14-5)=(t14)-(t5)$

Notice that this expression matches with the one shown in the the second option.
