Step-by-step explanation:
x2^+8x=-20
9x^2=20
x^2=20-9
x^2=11
√x^2=√11
x=√11
You will need to subtract 3x from 5x, then since there is a minus sign in front of the 7 it will count as a -7, so u add 7 cross it out and then add 7 to the -4(which is also negative cause it has a minus sign in front) and then you have ur answer
5x-3x=2x
7+ -4= 3
Answer: 2x-3
X=total number of pages.
1)we calculate the total number of pages.
32% of x =80
(32/100)x=80
x=(80*100)/32
x=250.
2) we calculate the number of pages don´t read.
number of pages don´t read=250-80=170
Answer: 170 pages.
All you have to do is set the equation
We call Rick r and Jim j
r+j=49500
r= 3j-500 because rick is 500 when Jim is 3 times his amount.
So all you have to do left is solve it.
Subtitles
3j-500+j=49500
4j=50000
J= 12500 dollars
Subtitles
R= 3(12500)-500= 37000 dollars
In conclusion rick salary is 37000 and Jim is 12500
Hope this helps and if it does please give a brainliest answer :)
