$\dfrac{2}{5}(x-4)=2x\ \ \ \ |multiply\ both\ sides\ by\ 5\\\\2(x-4)=10x\ \ \ \ |use\ distributive\ property:a(b-c)=ab-ac\\\\2x-8=10x\ \ \ |add\ 8\ to\ both\ sides\\\\2x=10x+8\ \ \ \ |subtract\ 10x\ from\ both\ sides\\\\-8x=8\ \ \ \ |divide\ both\ sides\ by\ (-8)\\\\\boxed{x=-1}$

Adam is in mexico where the temperature is given degrees celsius . To convert to fahrenheit you multiply the celsius temperature

Anestetic [448]

Answer:

When temperature is 30 in degrees Celsius then temperature in degree Fahrenheit is 86.

Step-by-step explanation:

Let C denotes the temperature in degree Celsius and F denotes the temperature in degree Fahrenheit.

According to the given question,

To convert to Fahrenheit we multiply the Celsius temperature by 9/5 and add 32.

Mathematically it can be written as,

$F=C\times\frac{9}{5}+32$

For example , let us take the temperature in mexico to be 30 degrees Celsius to convert the temperature to Fahrenheit we can use this equation as ,

$F=C\times\frac{9}{5}+32$

Put C = 30, we get

$\Rightarrow F=30\times\frac{9}{5}+32$

$\Rightarrow F=6 \times 9+32$

$\Rightarrow F=54+32$

$\Rightarrow F=86$

Thus, when temperature is 30 in degrees Celsius then temperature in degree Fahrenheit is 86.
