Hi, I would be glad to help you here. 

<span>7x − 2 < 3 + 2x 

Move terms 

7x - 2x - 2 < 3 

Collect the like terms

(7x - 2x) = 5x (<3 + 2 stays the same) 

Calculate 

5x (<3 + 2 = 5) 

5x <5 

Divide both sides of the inequality by (5) giving you, 

x < 1 

So, finally in a total the correct answer here is (x < 1)

MATH HELP ME ASAP!!!!
ziro4ka [17]

Answer:

You get 12$ per B and 15$ per A.  Thus, the answer is A) $282

Step-by-step explanation:

4A+4B=108

Divide by 4

A+B=27

Subtract B

A = 27 - B

3A+5B=105

Substitution

3(27-B)+5B = 105

Distribute

81-3B+5B=105

Combine like terms

81+2B=105

Subtract 81

2B=24

Divide by 2

B = 12

A = 15

14(15)+6(12)=x

210+72=x

282=x
