kogti [31]

Answer:

67.5

Step-by-step explanation:

I've learned this multiple ways but in my opinion this is the easiest. Just times everything together so, 40 x 2.5 x 1.2 which equals 135 and then divide 135 by 2 which equals your answer of 67.5 which is rounded to the nearestt tenth already.

-1/4d-2/5d=39 Solve for d Please explain I don’t understand

Papessa [141]

Given:

The equation is

$-\dfrac{1}{4}d-\dfrac{2}{5}d=39$

To find:

The value of d.

Solution:

We have,

$-\dfrac{1}{4}d-\dfrac{2}{5}d=39$

Taking LCM, we get

$\dfrac{-5d-8d}{20}=39$

$\dfrac{-13d}{20}=39$

Multiply both sides by 20.

$-13d=39\times 20$

Divide both sides by -13.

$d=\dfrac{39\times 20}{-13}$

$d=-3\times 20$

$d=-60$

Therefore, the value of d is -60.
