Hello :
<span>a line that is parallel to the line represented by the function below? y=2/5x+9
has same slope : 2/5
an equation is: y =( 2/5)x+b</span>
Answer:
d = or d = 5.1
Step-by-step explanation:
The entire thing or just a specific part such as the letter?
K so you have to set 2 equations like this
x meaning the amount of adults
and y meaning the amount of kids
x+y=11
13.5x+8.25y=111.75
Then use substitution method and you get
x=11-y from the first equation
plug that in to the second and you get
13.5(11-y)+8.25y=111.75
Solve for y in that equation by distributing and then combining like terms
148.5 - 13.5y + 8.25y = 111.75
148.5 - 5.25y = 111.75
Then, you need to subtract 148.5 from each side and cancel the negatives
5.25y=36.75
solve for y and you get
36.75/5.25 = 7
y=7
