Answer:
11) x = 45
12) x = 30
Step-by-step explanation:
11)
3x + x = 180
4x = 180
x = 45
12)
4x = 5x - 30
4x - 5x = -30
-x = -30
x = 30
Set it up like a ratio: pipes on the top and minutes on the bottom. Therefore, your ratio would be 4/70 = 7/x. Cross-multiply to get 4x=490 and x = 122.5 minutes. Change that to hours if you'd like by dividing by 60!
Answer:
If we are talking about just 8p, this means there are 8 total p's.
Step-by-step explanation:
The reason for this is because we are multiplying 8 by p, which gives us a total of 8 p's and simplifies to 8p.

Hello,
In Q5. Being a straight line the angles are supplementary to each other.
And x = 70°
In Q6.
The angles sum up to 90° , so 25x + 30° = 90
25x = 60°
x= 60°/25 = 2.4°
Hope this helps.
