Question

I need help on this question ASAP please?

Answer 1

Answer:

B.

Step-by-step explanation:

10c + 5 ≤ 45

10c ≤ 40

c ≤ 4

Since the inequality uses the less than or equal to sign, we use a shaded circle on the number line. Since c is less than or equal to 4, your answer will be B, since the line extends infinitely to the left of 4.

Hope this helps!

Answer 2

Answer:

B

Step-by-step explanation:

To get the answer, you need to simplify or re-write the equation given:

1. 10c + 5 ≤ 45 = 10 × c + 5 - (45) ≤ 0

Next, group the like terms together:

1. 10c - 40

Now, we can apply algebra to simplify the equation further:

1. (10c ÷ 10) ≤ (40 ÷ 10)
2. c ≤ 4

Now, look at your options. Only option B matches our equations. Therefore, B is the correct answer.
