Ineed the answer. can’t figure it out. tried to solve it for the past 2 hours, but ended up in a dead end.

13) D. 18

14A) 112¾ inches

14B) 5⁵/₉

Step-by-step explanation:

13. Find the greatest common factor.  First, write the prime factorization of each number.

18 = 2 × 3²

36 = 2² × 3²

54 = 2 × 3³

Use the smallest exponent of each factor to find the GCF.

GCF = 2 × 3²

GCF = 18

You can make up to 18 identical baskets.

14. The walkway is 9 bricks wide and 25 bricks long.

The width in inches is:

9 × 2¾

= 9 × 11/4

= 99/4

= 24¾

The length in inches is:

25 × 5½

= 25 × 11/2

= 275/2

= 137½

Part A. The difference is:

137½ − 24¾

= 275/2 − 99/4

= 550/4 − 99/4

= 451/4

= 112¾ inches

Part B. The ratio is:

137½ / 24¾

= (275/2) / (99/4)

= (275/2) × (4/99)

= 50/9

= 5⁵/₉

answer:   n ≤ -3 or n < -5

step-by-step explanation:

-5 + 2n ≥ -11

+5             +5

2n ≥ -6

2/2 ≤ -6/2

n ≤ -3

-6 - 10n > 44

+6           +6

-10n > 50

-10/-10 50/-10

n < -5

idk man good luck man
