Elan Coil [88]3 years ago
4 0

Answer:

  • Jenny 1.75 miles, Keith 4.75 miles, Jonna 9.5 miles

Step-by-step explanation:

<u>Distance per person:</u>

  • Jenny - x, Keith - y, Joanna - z

<u>Equation as per given:</u>

  • y = x + 3
  • z = 2y = 2(x + 3)
  • x + y + z = 16

<u>Substitute and solve for x:</u>

  • x + (x + 3) + 2(x + 3) = 16
  • 2x + 3 + 2x + 6 = 16
  • 4x = 7
  • x = 7/4 = 1.75

Then

  • y = 1.75 + 3 = 4.75
  • z = 4.75*2 = 9.5

HELP ME ASAP I HAVE SO MANY QUESTIONS THAT WILL SAY THIS BUT HELP MEEE!!!(timed!!)
tester [92]

Answer:

1. $8.30

Step-by-step explanation:

so 3 hats were purchased and each cost 15.50 so

15.50*3=46.50

and the rest of the 96.30 is 6 keychains so

96.30-46.50=49.80

and there is 6 keychains

49.80/6=8.30

Each key chain was $8.30

Claire's answer is unreasonable because when we got the price of the keychains all together in Claire's mind the total for the keychains would be $4.98, which we clearly got the total for the keychains at $49.80.
