Answer:
D
Step-by-step explanation:
6 x 1/3 = 2
1/3 x (12-3) = 2 x 9
2 x 9 = 18
A = 2 (12/3) = 2 x 4 = 8
B = 2 x 15 = 30
C = 2 x 36 = 72
D = 2 x 9 = 18
33-7n is the required expression.
Have a nice day!!
Answer: x = 11
Step-by-step explanation:
You didn't state what you needed for these problems so I'm going to assume you need to solve for X.
1st Equation:
3x - y = 23 --> y = 3x - 23
2nd Equation:
2x + 3y = 8 --> (3y = 8 - 2x)/3 = y = 8/3 - 2x/3
Set Equations = to Each other
3x - 23 = 8/3 - 2x/3 --> 3x - 2x/3 = 8/3 + 23
9x/3 - 2x/3 = 8/3 + 69/3 --> 7x/3 =77/3
7x/3 X 3/7 = 77/3 X 3/7
x = 11
If you need to solve for y as well plug the x value back into the original equation and solve.
Hello!
We can write this as a proportion below.
As you can see, 4 is eight times 0.5. Therefore, we can multiply eighteen by eight to get our answer.
18(8)=144
Just to check, we can cross multiply and divide.
72/0.5=144
Therefore, our answer is
144 feet.
I hope this helps!
