It would cost $105 because if you do 13+13+13= 39
22+22+22= 66
66+39= 105.
Answer:
I think it's x=-12 for the buttom one
Step-by-step explanation:
I think when you get open equations like these you would asume 1 is there so rewrite it as 2x + 25 = 1
so take the 25 away from 1. to do that we need to do the opisite of +
2x + 25 = 1
1 - 25 = -24
rewrite
2x = -24
take the 2 away. oppisite of mulitplication is division. so divide 2 by -24
-24 divided by 2 = -12
Hope this helps! Please mark as brainliest! Thanks! If you need me to solve the top one too, I'll do it! Just comment bellow. :D
<span>volume = l x w x h</span>
<span> to increase volume by 3 you would have 3*l*w*h </span>
<span>so 3*l*w*h= l*2*w* x *h ( x is the scale factor)
</span><span> cancel out the l w and h on both sides
3 = 2x
Divide both sides by 2
x = 3/2 = 1.5
</span><span> the height should increase by a factor of 1.5</span>
214 grams......(t.i.d.) means 3 times per day.....214/3 = 71.33 per dose
71.33/34 = 2.09......so that is 2 tabs per does.......that would be 6 tabs per day....6 x 30 = 180.....180 tabs for a 30 day supply
