24w+6c=$23.40
5w+2c=$6.60
So you have to find c (chips) first. You have to make the number of chips in both equations cancel each other.
-3(5w+2c)=-3($6.60)
-15w-6c=$-19.80
Then subtract to get one formula
24w + 6c = $23.40
-15w - 6c = $-19.80
9w = $3.60
w=$.40
To check your answer, find how much one bag of chips costs:
5($.40) + 2c = $6.60
$2.00 + 2c = $6.60
2c = $4.60
c=$2.30
Plug your value for one water and one bag of chips into the formula:
5($.40) + 2($2.30)
$2.00 + $4.60
=$6.60
Then plug your values into the original problem:
24($.40) + 6($2.30)
$9.60 + $13.80
=$23.40

Answer: 45 degrees I think.
Step-by-step explanation: Based off of looks alone, one could conclude that 3x is approximately 0.5 degrees larger than 2x, 2x is approximately 90 degrees, and that x is approximately half of 2x. so based purely off of observation, it appears that x is approximately 45 degrees. you can multiply x by the number by in it in each instance.
x=45, 2x=90, and 3x=135
