15 because I do it like 12+3 because the 3 is negative
Since each side is r times the side of ABC, then 30*r+40*r+60*r is the perimeter, which equals 130r (by separating it into r*(30+40+60) using the distributive property)

Answer:
y = -⅓x + 3
Step-by-step explanation:
To find the equation of the graph in the form of y = mx + b (slope-intercept form), we have to find the slope (m) and the y-intercept (b) of the graph:
Slope (m) = change in y/change in x
Slope (m) using the two points on the line, (0, 3) and (3, 2):
m = (2 - 3)/(3 - 0) = -1/3
m = -⅓
y-intercept (b) = 3 (the y-axis is intercepted at this point)
✔️To write the equation, substitute m = -⅓ and b = 3 into y = mx + b:
Thus,
y = -⅓x + 3
Answer:
Bags of chocolates pieces = 10 bags
Bags of peanut butter pieces = 15 bags
Step-by-step explanation:
The ratio of chocolate pieces to peanut butter pieces
($4.23-$ 3.79) : ($ 4.89 - $4.23)
= $0.44 : $0.66
= 2 : 3
Therefore; the fraction of chocolate pieces bag = 2/5
Thus; Number of bags of chocolate pieces = 2./5 × 25
= 10 bags
Fraction of peanut pieces bags = 3/5
Therefore; Number of bags of peanut butter pieces = 3/5 × 25
= 15 bags
