Answer:
Step-by-step explanation:
y ∞ x/m
y = kx/m
Where k is the constant of proportionality
A. k = ym/x
y=5 when x=7 and m=4
k = (5×4)/7
k = 20/7
y = 20x/7m
B)the value of when x=2and m=2
y = 20x/7m
y = (20×2)/(7×2)
y = 40/14
y = 20/7
y = 2 6/7
C. The value of m when y=2 and x=4
y = 20x/7m
7ym = 20x
m = 20x/7y
m = (20×4)/(7×2)
m = 80/14
m = 40/7
m = 5 5/7
Answer:
y= -5
Step-by-step explanation:
-3(4) +9y = 57
-12 + 9y = 57
-12 + 12 + 9y = 57 + 12
9y/9 = -45
y= -5
It’s -3 mate good luck on your test :)
X = dimes
6x = nickels
x + 6x = 91
7x = 91
x = 91/7 = 13
13 dimes and 78 nickels
