30x+ 600 ≥ 1,500

Answers

Answer:

x ≥ 30

Step-by-step explanation:

30*30 = 900 and when we add 600 to that, we get 1,500 which is the lowest possible number for the left side of the equation to equal. If x equals anything above 30, then it will automatically equal a number greater than 1,500 when added to 600.

(sorry this is confusing, I'm not very good at explaining things. I hope it helped anyway)

Answer:

x > 30

Step-by-step explanation:

replace > with=

30x +600=1500

take 600 to the other side

30x=1500-600

30x=900

x=30

therefore x > 30

James used substitution to solve this system of equations. Which could be the result of his first step
2x+3y=12
y=x+1.5
A..y=2x+3y+1.5
B.2x+3(x+1.5)=12
C.2x+3x+1.5=12
D.y=2x+3y

Answers

the answer would be B. :)
B, it's B because the system gives you what Y equals and so you need to substitute (x+1.5) for the y in your equation. From there solve to get- 2x+3x+4.5=12. From here you will want to add like terms, 2x+3x= 5x. Your new equation should look like this- 5x+4.5=12. From here solve for x.
