Please help! Which is the solution set of the following inequality?
Ira Lisetskai [31]

Answer:

x<3

Step-by-step explanation:

3x - 4 < 17 - 4x

So, the -4 shall cross to the other side and replace the -4x which will now take the place of where the -4 used to be and the signs of both digits will change to a positive (+)

Remember the inequality sign (<) shall not change

so now the equation shall appear like this;

3x + 4x < 17 + 4

add both sides and it will appear like this;

7x < 21

simplify both sides by 7 and you'll get

x < 3

What percent is of 30 is 40
Hoochie [10]

Answer:  

30/x=100/40

(30/x)*x=(100/40)*x       - you multiply both sides of the equation by x

30=2.5*x       - you divide both sides of the equation by (2.5) to get x

30/2.5=x  

12=x  

x=12

now we have:  

40% of 30=12
