11. Solve the equation.
–3 + x = 11 (1 point)
–8
–14
8
14
To solve the equation –3 + x = 11, we need to isolate the variable x on one side of the equation.
Adding 3 to both sides, we get:
–3 + x + 3 = 11 + 3
Simplifying:
x = 14
Therefore, the solution is x = 14. Answer: (d) 14.
13. Solve the equation.
b over negative four = –2 (1 point)
8
–8
one half
–negative one half
To solve the equation b/(-4) = -2, we need to isolate the variable b on one side of the equation.
Multiplying both sides by (-4), we get:
b = (-4)*(-2)
Simplifying:
b = 8
Therefore, the solution is b = 8. Answer: (a) 8.
15. Jim owns a small business. There was a loss of $26 on Thursday and a loss of $11 on Friday. On Saturday there was a loss of $9, and on Sunday there was a profit of $13. Find the total profit or loss for the 4 days. (1 point)
$33 loss
$59 profit
$19 loss
$26 profit
To find the total profit or loss over the four days, we need to add up all of the gains and losses.
Starting with the losses:
Loss on Thursday = -$26
Loss on Friday = -$11
Loss on Saturday = -$9
Total loss = -$26 + (-$11) + (-$9) = -$46
Now, adding the profit on Sunday to get the overall profit or loss:
Total profit/loss = -$46 + $13 = -$33
Therefore, the total profit or loss over the four days was a loss of $33. Answer: (a) $33 loss.
