Kamilah’s weight has tripled since her first birthday. If w represents the amount Kamilah weighed on her first birthday, write a

S_A_V [24]

Answer:

3*w

Step-by-step explanation:

Kamilah now weighs the triple of what she weighed on her first birthday. That means we need to multiply the first weight by 3. As the first weight is w, she now weighs 3*w.

Another possible expression is to sum 3 times w, that is w + w + w (it's equal to 3*w).

Can someone pls help me / alguien me puede ayudar

Answer:

The simplified expression is:

$\frac{2}{5}y+\frac{1}{5}x-0.2y-6+\left(-2\right)=0.2y+0.2x-8$

Step-by-step explanation:

Given the expression

$\frac{2}{5}y+\frac{1}{5}x-0.2y-6+\left(-2\right)$

$\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a$

$=\frac{2}{5}y+\frac{1}{5}x-0.2y-6-2$

$\mathrm{Group\:like\:terms}$

$=\frac{2}{5}y-0.2y+\frac{1}{5}x-6-2$

Add similar elements

$=0.2y+\frac{1}{5}x-6-2$

$=0.2y+\frac{x}{5}-6-2$

$=0.2y+\frac{x}{5}-8$

$=0.2y+0.2x-8$

Thus, the simplified expression is:

$\frac{2}{5}y+\frac{1}{5}x-0.2y-6+\left(-2\right)=0.2y+0.2x-8$
