Answer:
(3/5)x+1/4=(3/4)x-2/5
<=> (3/5)x - (3/4)x= -2/5 - 1/4
<=> x(12/20 - 15/20) = -13/20
<=> x(-3/20) = -13/20
<=> x = 13/3

Answer:
<h3>
second term minus first term </h3>
Step-by-step explanation:
Difference is a result of subtracting (not dividing!)
To calculate difference between two terms we have to subtract the previous from the next:
![d=a_2-a_1=a_3-a_2=a_4-a_3=...=a_n-a_{n-1}](https://tex.z-dn.net/?f=d%3Da_2-a_1%3Da_3-a_2%3Da_4-a_3%3D...%3Da_n-a_%7Bn-1%7D)
Answer:
Answer: y=3/2x+1
To find a line that is perpendicular, invert the slope and multiply by -1
so the original slope is -2/3,
invert it to get -3/2 then multiply by -1 to get 3/2
Put the given point (-2,-2) and the new slope into point intercept form: y+2=3/2(x+2)
Rewrite in standard form to get y=3/2x+1
Answer:
"490 grams" would be the correct solution.
Step-by-step explanation:
The given values are:
Half time,
T = 35 days
Total time,
t = 105 days
As we know,
⇒ ![A=A_o(\frac{1}{2} )^{\frac{t}{T} }](https://tex.z-dn.net/?f=A%3DA_o%28%5Cfrac%7B1%7D%7B2%7D%20%29%5E%7B%5Cfrac%7Bt%7D%7BT%7D%20%7D)
On substituting the values, we get
⇒ ![=3920\times (\frac{1}{2})^{\frac{105}{35} }](https://tex.z-dn.net/?f=%3D3920%5Ctimes%20%28%5Cfrac%7B1%7D%7B2%7D%29%5E%7B%5Cfrac%7B105%7D%7B35%7D%20%7D)
⇒ ![=3920\times (0.5)^3](https://tex.z-dn.net/?f=%3D3920%5Ctimes%20%280.5%29%5E3)
⇒ ![=3920\times 0.125](https://tex.z-dn.net/?f=%3D3920%5Ctimes%200.125)
⇒ ![=490 \ grams](https://tex.z-dn.net/?f=%3D490%20%5C%20grams)
