JulsSmile [24]

Answer:

24 days

Step-by-step explanation:

120 students =30 days

120+30 =150 students

MORE/LESS METHOD

120 students (a) : 30 days(y)

150 students (b) : x

Find the value of x using the formula: a/b × y

If you think the value of x will be more than y then the bigger number will be the numerator. If u think x will be less, then the smaller number will be in the numerator.

I predict that x will be less than y

THEREFORE... 120/150 ×30

= 24 days

Ellen works as a teller at a bank downtown. On Monday morning, Ellen left her house at 6:41 A.M. It took Ellen 10 minutes to wal
faltersainse [42]

The time that Ellen arrived at the bank was <u>7:02 A.M</u>.

<h3>What is the time?</h3>

Ordinarily, time is an ongoing and continuous sequence of events that occur in succession, from past through present, and to the future.

For our purpose, we can explain that time is a measure of years, months, weeks, days, hours, minutes, and seconds during which events occur.

Time is also a measure of the distance covered against the speed.

<h3>Data and Calculations:</h3>

The time Ellen left her house was 6:41 A.M.

The time Ellen took to walk to the subway = 10 minutes

Ellen reached the subway station at 6:51 A.M. (41 + 10)

The time that the subway ride took to reach the bank = 11 minutes

Therefore, Ellen arrived at the bank at 7:02 A.M. (51 + 11).

Thus, the time that Ellen arrived at the bank, where she works as a teller, was <u>7:02 A.M</u>.

Help needed ! 13 - 2(2x + 1) = 1 ?
kirill115 [55]

Answer:

x = ¹⁰⁄₄,⁵⁄₂, or 2.5

Step-by-step explanation:

Given: 13 - 2(2x + 1) = 1

1. Distribute -2 through the parentheses:

⇒ 13 - 2(2x + 1) = 1

⇒ 13 + (-2)(2x) + (-2)(1) = 1

13 - 4x - 2 = 1

2. Combine like terms:

⇒ 13 - 4x - 2 = 1

⟹ 11 - 4x = 1

3. Subtract 11 from both sides:

⇒ 11 - 11 - 4x = 1 - 11

⟹ -4x = -10

4. Divide both sides by -4:

⇒ -4x ÷ -4 = -10 ÷ -4

⟹ x = ¹⁰⁄₄,⁵⁄₂, or 2.5

5. Check your work:

⇒ 13 - 2(2x + 1) = 1

⇒ 13 - 2(2(2.5) + 1) = 1

⇒ 13 - 2(5 + 1) = 1

⇒ 13 - 2(6) = 1

⇒ 13 - 12 = 1

⟹ 1 = 1 ✔
