The selected answer is correct
Answer:
16 units
Step-by-step explanation:
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:
y=19.2. because x=8 when x multiply by 1.6, so y should multiply by 1.6 to get 19.2
Step-by-step explanation:
D
A nonproportional relationship is a linear line that doesn’t go through the origin.
y=3x+0 does go through the origin because the y-intercept (the b) is 0
Y=x/4 also has a y-intercept of 0
Y=7x also has a y-intercept of 0.
y=2/5x+7 does not go through the origin because the line passes the y-axis at (0,7) which is the y-intercept.
