So, you need to do the same operation to each side.
Start out by subtracting 3 from each side
1/4 (20x+8) = -3
Then, multiply both sides by 4
40x+8 = -12
Then, subtract 8 from each side
40x = -20
divide both sides by 40 and you get
x=-1/2
Hope this helped!
Answer:
The percent of pages Jace read at school is
× 100 = 15%
The percent of pages Jace need to read at home is 100% - 15% = 85%
Step-by-step explanation:
Scale 1: One division represents 100% ÷ 20 divisions = 5%
Scale 2: One division represents 20 pages ÷ 20 divisions = 1 page
The proportion that can be used to determine the percentage of pages Jace read at school is 3 out 20 pages = ![\frac{3}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B20%7D)
Jace need to read 20 -
=
pages at home.
That is
× 100 = 85%
Answer:
13791
Step-by-step explanation:
Take 96,537 and divide by 7
125 bc 15/5 is 3 so 375/3 equals 125
Answer:
![$ \frac{7 +4a}{-6 + 12a} $](https://tex.z-dn.net/?f=%24%20%5Cfrac%7B7%20%2B4a%7D%7B-6%20%2B%2012a%7D%20%24)
Step-by-step explanation:
Given: f(x) = ![$ \frac{7 + x}{-6 + 3x} $](https://tex.z-dn.net/?f=%24%20%5Cfrac%7B7%20%2B%20x%7D%7B-6%20%2B%203x%7D%20%24)
Now to determine f(4a) substitute 4a in the place of x.
⇒ f(4a) = ![$ \frac{7 + 4a}{-6 + 3(4a)}](https://tex.z-dn.net/?f=%24%20%5Cfrac%7B7%20%2B%204a%7D%7B-6%20%2B%203%284a%29%7D)
⇒ f(4a) = ![$ \frac{7 + 4a}{-6 + 12a} $](https://tex.z-dn.net/?f=%24%20%5Cfrac%7B7%20%2B%204a%7D%7B-6%20%2B%2012a%7D%20%24)
