Mathematics
1 answer:
kipiarov [429]3 years ago
8 0

Answer:

Step-by-step explanation:

George: x

Alex: x + 12

Carl: 3(x+12)

3x+36+x+x+12= 68

5x + 48 = 68

5x = 20

x = 4; George's age

4 + 12 =  16; Alex's age

3(4+12)= 3(16)= 48; Carl's age  

George to Alex: 4:16 = 1:4

Alex to Carl: 16:48= 1:3

George to Carl 4:48= 1:12

Carl to Alex: 48:16 = 3:1

What is the solution set of this inequality?
vitfil [10]

Answer:

C. I > 4 (or x > 4)

Step-by-step explanation:

first multiply 8 and (x - 5)

8(x– 5) – 3x > -20 -----> (8 * x) - (8 * 5) = 8x - 40 - 3x > -20

add like terms

8x - 40 - 3x > -20 -----> 8x + -3x = 5x - 40 > -20

combine -40 and - 20

5x - 40 > -20 ----> -20 + 40 = 5x > 20

Then finally divide

5x > 20 -----> (5x/5) > (20/5) = x > 4
