Answer:

The value of x = -13

Step-by-step explanation:

Given the expression

$\frac{0.2x+1}{2}=-0.8$

Multiply both sides by 2

$\frac{2\left(0.2x+1\right)}{2}=2\left(-0.8\right)$

simplify

$0.2x+1=-1.6$

Subtract 1 from both sides

$0.2x+1-1=-1.6-1$

Simplify

$0.2x=-2.6$

Divide both sides by 0.2

$\frac{0.2x}{0.2}=\frac{-2.6}{0.2}$

Simplify

$x=-13$

Therefore, the value of x = -13

Answer:

$\frac{6}{20} \ mile\ per\ hour$

Step-by-step explanation:

Given:

For every 1/2 of an hour that the turtle is crawling, he can travel 3/20 of a mile

Question asked:

At what unit rate is the turtle crawling?

Solution:

As here time taken is given and the distance traveled is also given and hence we will apply speed and distance formula to find rate of crawling of turtle.

Time taken by turtle = $\frac{1}{2} \ hour$

Distance which can be traveled by turtle = $\frac{3}{20} \ miles$

$Speed =\frac{Distance}{Time}$

$=\frac{3}{20} \div\frac{1}{2} \\\\ =\frac{3}{20} \times\frac{2}{1} \\ \\ =\frac{6}{20}$

Therefore, the rate at which the turtle is crawling is $\frac{6}{20} \ mile\ per\ hour$
