One month, Kcee worked 6 hours more than Alberto, and Atiana worked 4 times as many hours as Kcee. Together they worked 126 hour

alina1380 [7]

Answer:

no of hours worked by Kcee = 16 hours

no. of hours worked by Kcee = 22

no. of hours worked by Atiana = 88

Step-by-step explanation:

Let the no. of hours worked by Alberto be x

given that

Kcee worked 6 hours more than Alberto

no. of hours worked by Kcee = x + 6

Given

Atiana worked 4 times as many hours as Kcee

no. of hours worked by Atiana = 4*no. of hours worked by Kcee

no. of hours worked by Atiana = 4*(x + 6) = 4x + 24

Total hours worked by them together in terms of x = x + x + 6 + 4x + 24

Total hours worked by them together in terms of x = 6x + 30

As given Together they worked 126 hours

6x + 30 = 126 hours

6x = 126 - 30

6x = 96

x = 16

Thus, no of hours worked by Kcee = x = 16 hours

no. of hours worked by Kcee = x + 6 = 16 + 6 = 22

no. of hours worked by Atiana = 4x + 24 = 4*16 + 24 = 64 + 24 = 88

6(x + 3) - 2 < 8(x + 5)

stira [4]

The answer is $x>-12$

First you must use distributive property to simplify.

$6x+18-2$

Then, you must subtract 18 on both sides

$6x-2$

Next, add 2 on both sides

$6x$

Then, subtract 8x on both sides

$-2x$

Finally, Divide both sides by -2. Don't forget to switch the equality sign because the variable was changed to a positive using division.

$x>-12$
