Just distribute -5
30u+15x-20
Don’t forget to change negative signs to positive signs if their multiplied by negatives
Let b>a...
b=2(a+4)
b=2a+8 then we are told that:
b-a=11 using b found above in this equation gives you:
2a+8-a=11 combining like terms on left side
a+8=11 subtracting 8 from both sides
a=3
So the smaller number is 3.
...
since b=2a+8
b=14
check..
b=2(a+4)
14=2(3+4)
14=2(7)
14=14
and
b-a=11
14-3=11
11=11
The answer to your question is b
1 . 48 is the answer as the two bottom ones are equal 180-66-66=48
2. 117 degrees as the angle is the same as the other congruent angle shown in the diagram
This is the graph for the equation y=2x-4.
