The answer is the first one
Answer:
x=8
Step-by-step explanation:
normally it would be 2x-1=x+9 so now we have to combine the x into one fraction which will be 2x-1=+9 now for my way i will be taking the -1 to the other side and when that happens its going to become positive so now the answer will be 2x=+10 ok so now we have to have the x's to the same side so i have to drag the fraction to the other side and making it positive which will conclude into 1.25x=10 and now 10 divided by 1.25 is 8 so the answer is x=8 (sorry for the ok nows) hope this helped
Step-by-step explanation:
C. The system of equations is unsolvabl
For sake of convenience, reverse the series, then it would be:
21,19,17.....7
a=21, d = -2,
s(4) = 4/2 (21+15)
s(4)=2(36)
s(4) = 72
3. A=bh/2
2A=bh
h=2A/b.
8. Dy-Cx=E
Dy=E+Cx
y=(E+Cx)/D
