Answer:
Step-by-step explanation:
Isolate x on one side of the equation.
First, do parenthesis.
4(2+3)
Add.
3+2=5
Multiply.
4*5=20
Rewrite the equation problem.
x+20<5x
Secondly, subtract 20 from both sides.
x+20-20<5x-20
Solve.
x<5x-20
Thirdly, subtract 5x from both sides.
x-5x<5x-20-5x
Solve.
5-1=4
-4x<-20
Then, multiply -1 from both sides.
(-4x)(-1)>(-20)(-1)
Solve.
(-4x)(-1)=4x
(-20)(-1)=20
4x>20
Divide by 4 from both sides.
4x/4>20/4
Solve.
20/4=5
x>5
The solutions is 5, therefore, the correct answer is x>5.

Step-by-step explanation:
sinP = = =
sinR = =
Because the angles are vertical angles, they are equal.
Set the equations equal to each other:
5x+100 = 3x+112
Subtract 100 from 112:
5x = 3x+12
Subtract 3x from 5x:
2x = 12
Divide 12 by 2:
x = 6
x is equal to 6
Answer:
Martin's graph shows a proportional relationship because Isabelle had to pay 3 extra dollars.
Step-by-step explanation:
Martin's equation y=5x
Isabelle's equation y=5x+3
I put a picture of the lines graphed on the graph.
I hope this helps and have a great day.
Im guessing those are those brackets?
