Multiple Choice
Solve.
2.7 ≤ b + 5
(1 point)
b ≥ 7.7
b ≥ –2.3
b ≤ 2.3
b ≤ –7.7
The correct answer is: b ≥ –2.3
To solve the inequality 2.7 ≤ b + 5, you can follow these steps:
1. Subtract 5 from both sides of the inequality:
2.7 - 5 ≤ b + 5 - 5
-2.3 ≤ b
Therefore, the correct solution is b ≥ -2.3.
To solve the inequality 2.7 ≤ b + 5, we need to isolate the variable "b" on one side of the inequality symbol.
First, subtract 5 from both sides of the inequality:
2.7 - 5 ≤ b + 5 - 5
Simplifying the equation:
-2.3 ≤ b
Therefore, the correct answer is:
b ≥ -2.3
A)
You have a gift card for your favorite clothing store for the amount of $60. You have found a shirt you want to buy that costs $15. If you don't
want to spend more than the amount of the gift card, which of the following inequalities could be used to determine the amount you have left to
spend?
(1 point)
x + 15 ≥ 60
x – 15 ≥ 60
x – 15 ≤ 60
x + 15 ≤ 60
To determine the amount you have left to spend, you need to subtract the cost of the shirt, $15, from the total amount of the gift card, $60.
Let x represent the amount you have left to spend.
Therefore, the correct inequality to represent this situation is:
x ≤ 60 - 15
Simplifying the equation:
x ≤ 45
So, the correct answer is x ≤ 45.
