Answer:

A) 5 and B) 5

Step-by-step explanation:

A) 5x-12=13

+12 +12 (add 12 to the 13)

5x=25

(then divide 25 by 5 which is 5 so the answer is 5)

B) 8(x+3)=64 (first use distributive property)

8x+24=64

-24 -24 (then subtract 24 to 64 which is 40)

8x=40

(then divide 40 by 8 which is 5 so that is it!)

I believe this is correct, I hope this helps :D

Nonamiya [84]

Answer:

The probability is 6/13

Step-by-step explanation:

Number of zucchini seed packets = 24

Number of other seed packets = 28

Total number of packets = 24 + 28 = 52

Probability is given by

$P(E)=\frac{n(E)}{n(s)}\\\\n(E)=24,n(s)=52\\P(E)=\frac{24}{52}\\\\P(E)=\frac{6}{13}$
