Answer:
Y=42 and x=7
Step-by-step explanation:
Referring that both angles equal each other we will us an = in both equations
2y-27=y+15
Subtract y from both sides
y-27=15
Now add 27 to both sides
y=42
Now check the solution
2(42)-27=57
(42)+15=57
So it is true! y equals 42!
_____________________________________________
3x+4=5x-10
Subtract 3x from both sides
4=2x-10
Now add 10 to both sides
14=2x
Now divide both sides by 2
7=x
Now check the solution
3(7)+4=25
5(7)-10= 25
so it is true x=7!
- - 9+7=16
And you can do:
10+6=16 aswell. <span />
Answer: −50x−66
Step-by-step explanation:
4(10x+6)−10(9x+9)
Distribute:
=(4)(10x)+(4)(6)+(−10)(9x)+(−10)(9)
=40x+24+−90x+−90
Combine Like Terms:
=40x+24+−90x+−90
=(40x+−90x)+(24+−90)
=−50x+−66
If you get 4.4 interest in 1 year and 6 months is half of year, take half of 4.4 and multiply if by 550. Getting 1,210.
