2j+6a = 24

5j+3a =21

multiply the 2nd equation by -2

-10j -6a = -42

add the 1st and the modified 2nd together

2j+6a = 24

-10j -6a = -42

---------------------

-8j = -18

divide by -8

j = 2.25

substitute into

2j+6a = 24

2(2.25) +6a =24

4.50 +6a =24

subtract 4.5 from each side

6a = 19.50

divide by 6

a = 3.25

Answer:

jelly beans are 2.25 per pound

almonds are 3.25 per pound

Trish is going to camp for 50 days on 15 July 2022. Calculate the date when he will return from camp

Free_Kalibri [48]

Answer:

Trish is going to return from camp September 3rd, 2022.

Step-by-step explanation:

Okay! note: (There are 31 days in july)

July 15th+10 days=July 25th

July 25+6=July 31st

July 31st+1 day= August 1st

(17 days done so far)

August 1st+30 days=August 31st

(47 days done)

August 31st+1 day=September 1st

September 1st+2 days= September 3rd

I got the answer by breaking up the 50 days into smaller parts and adding them. Make sure you know how many days are in the months so you don't get too confused.
