Answer:
x=5.333
y=3
Step-by-step explanation:
given, y=5-2............(1)
1-3x+y=-12...............(2)
y=5-2=3
put y=3 in equ (2)
1-3x+3=-12
1+3+12=3x
3x=16
x=
x=5.333
hence, x=5.333
y=3 answer
Hey there!
Let's say that Julia has 50 CDs. We would plug this into c in the expression we've been given to find the number of CDs that Ahmed has.
c = 50
1/2c + 5
1/2(50) + 5
25 + 5
30
So, if Julia has 50 CDs, Ahmed has 30. We used the expression to figure that out and, therefore, that's why it was created.
Your answer will be the number of CDs that Ahmed has.
Hope this helped you out! :-)
The first option is correct. For the following question, the simplified expression for the volume is 8x3 + 14x2 + 3x.
Answer:
A
Step-by-step explanation:
5 and 7 are both common factors of 35 and 40
Looking at the options you can eliminate C and D right away because 7 times 8 = 56 and not 40 like the problem is asking.
This leaves A and B. Looking at the equation the difference between the two are the + and -
Using the original equation (35x-40) as reference we see that it subtracts the two variables. Therefore leaving A as the answer
