7 0

Answer:

x>48/5 or x<-3/2

Step-by-step explanation:

Solve for x

a) 12x + 7 < -11

12x < -11-7

12x < -18

x < -18/12

⇒ Simplify: divide the numerator by 6

x < -3/2

b) 5x – 8 > 40

5x > 40+8

5x > 48

x > 48/5

Therefore, x>48/5 or x<-3/2.

Circle=27, triangle=18, and square=26

Start with the second question. If you divide 36 by 2, you get 18 which is the value for the triangle. Now since you know the value of the triange you subtract it from 45. (45-18=27) 27 is the value of the circle. Lastly, subtract 27 from 53 to get the value of the square (53-27=26). Hope this helps!
