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.
the system has not solution
Explanation
given
Step 1
a) mutiply equation (2) by 8 to Make the x coefficients of one variable opposites.
b) now, add the result to equation(1)
when we get a indetermination it means the system has not solution , so the answer is
the system has not solution
I hope this helps you

Distribution of 500 visitors =100% attendees.
We remove a zero to find 1/10th. By converting 500 } 50/10 = 10 x 50
Step-by-step explanation:
when you add up; 40/10 + 25/10 = 4.0 + 2.5
and show 7.5 is the same as a + b + 1 x 100
and above 7.5 = 175/100 = 1 .75
Or use the counter x = multiply by 50
40/10 + 25/10 = 6.5
6.5-10 = 3.5
x =3.5 x 50
For this last one we can pose new question where 300 visitors was the original total then create new data for new question.
where x = multiply by 30 and create all to tenths etc.
We subtract the shown tenths only to find the total
Then same will apply above with new data.
