Answer:

Alyssa work at job A 9\ hours

Step-by-step explanation:

Let

x------> the number  of hours at work A

y------> the number  of hours at work B

we know that

x+y=24

y=24-x -----> equation A

6x+8.5y=181.5 -----> equation B

substitute equation A in equation B

6x+8.5(24-x)=181.5

6x+204-8.5x=181.5

8.5x-6x=204-181.5

2.5x=22.5

x=22.5/2.5

x=9\ hours

Anthony's weight is nine pounds more than twice his brothers weight. Anthony's weighs 59 pounds. how much does his brother weigh
ahrayia [7]
A = Anthony's weight
B = Anthony's brother's weight

  A = 2B + 9   Plug in Anthony's weight
59 = 2B + 9   Subtract 9 from both sides
50 = 2B   DIvide both sides by B
25 = B   Switch the sides to make it easier to read
  B = 25

Anthony's brother weighs 25 pounds.

Answer:

e = -1/2

Step-by-step explanation:

4/3 = -6e - 5/3

transfer -6e to the right

4/3 = -5/3 -6e

Find the LCM of 3,3and 1

and their LCM is 3. So, divide all through by 3

3(4/3) = 3(-5/3) - 6e × 3

4 = -5 -18e

combine

4 + 5 = -18e

9 = -18e

divide by -18

9/ -18 = -18e/ -18

-1/2 = e

e = -1/2
