Determine the value for AB
grin007 [14]

Answer:

x = 2

AB = 14

Step-by-step explanation:

2x(10) = 8(x+3)

20x = 8x + 24

subtract 8x from both sides

12x = 24

x = 2

Check:

4(10) = 8(5)

40 = 40

Correct

2x = 2 x 2 = 4

4 + 10 = 14

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!

Rom4ik [11]

Answer:

$1155

Step-by-step explanation:

Richard earns $10.50 per hour and he worked for 275 hours.

First find out the total amount he earns.

Total = 275 hours x $10.50 = $2887.50

40% of the earnings go to saving.

Now we find out how much is 40% of the earnings.

Saving = 40% of $2887.50 = 0.4 x 2887.5 = $1155
