Answer:
Let x = the 2nd number
Let x + 8 = the first number
Let 4x = the third number
x + x + 8 + 4x = 122
6x + 8 = 122
6x = 114
x = 19
x + 8 = 19 + 8 = 27
4x = 4(19) = 76
Step-by-step explanation:
The sum of three numbers is 122 . The first number is 8 more than the second. The third number is 4 times the second
Answer:
27.5 (is greater than) -2.5
>
Step-by-step explanation:
Distribute 5/3 to 6x and 9, (5/3•6x)+(5/3•9)=10x+15.
Set 10x+15 equal to 2x-5
10x+15=2x-5
(get rid of the smaller slope)
-2x -2x
8x+15=-5
+15 +15
8x=10
(divide by 8 to get the value of x)
8x divided by 8=x
10 divided by 8=1.25
x=1.25
Plug the known value of x back into the equations.
10(1.25)+15=27.5
2(1.25)-5=-2.5
27.5 (less than or equal to) -2.5 is incorrect. It would be
27.5 (is greater than) -2.5
