Formula for volume = length x height x breadth
7a) 13.5 x 3.5 x 11.5 = 543.375
7b) 24 x 10 x 30.5 = 7320
the abswer of this question is c
In order to make b the subject of this equation, we must isolate it on the left side. We can do this by following these steps:
![P = 2a+b](https://tex.z-dn.net/?f=P%20%3D%202a%2Bb)
Subtract b from both sides
![P - b = 2a+b-b](https://tex.z-dn.net/?f=P%20-%20b%20%3D%202a%2Bb-b)
![P-b=2a](https://tex.z-dn.net/?f=P-b%3D2a)
Subtract P from both sides
![P-b-P=2a-P](https://tex.z-dn.net/?f=P-b-P%3D2a-P)
![-b=2a-P](https://tex.z-dn.net/?f=-b%3D2a-P)
Now, we have isolated b, but it is negative. We can fix this by multiplying both sides of the equation by -1.
![-(-b)=-(2a-P)](https://tex.z-dn.net/?f=-%28-b%29%3D-%282a-P%29)
![b=-2a+P](https://tex.z-dn.net/?f=b%3D-2a%2BP)
Which is your final answer.
![b = -2a+P](https://tex.z-dn.net/?f=b%20%3D%20-2a%2BP)

Hope that helped! =)
Answer is d = 50.
Step by step. These are vertical angles so the (d + 70) will equal the opposite angle of 120.
Equation is d + 70 = 120.
Solve for d. Subtract 70 from both sides of the equal sign to solve for d.
d + 70 - 70 = 120 - 70
d = 50
