Answer:
y=105
Step-by-step explanation:
82+75+x=180
157+x=180
x=23
82+23=y
105=y
3x-2=3
3x=3+2
3x=5
x=5/3
Answer : According to the information provided in the question, the value of 'x' is 5/3
Answer:

Step-by-step explanation:
so you want to start by using y=mx+b
step one: find the slope (remember m is the slope in this)
m= 
m= 
m= 
m= - 
step two: insert the value we found for m into the equation and take one of the given points and insert the x and y into the equation (im using (0,5)) and solve for b.
y=mx+b
5= -4/3(0)+b
5=b
step three: rewrite y=mx+b with the values we found for m and for b

Answer:
1.)
y = 2x + 5 for x = 1
y = 2(1) + 5
y = 2 + 5
y = 7
2.) The function rule that relates the total cost of the party to the number of children n.
TCP = $60 + $4(n)
No, Perry is not using the correct ratio, because 15:17 is not equivalent to 5:7
15 divided by 3 is indeed 5 but divided 17 by 3 does not give you 7, nor a whole number.
I hope this helps.
