Answer:
Step-by-step explanation:
x + 25 + 4x + 10 = 180
5x + 35 = 180
5x = 145
x = 29
<1 = 29 + 25 = 54
<2= 4(29) + 10 = 116 + 10 = 126
Answer:
x (constant) = 20 ((month)) y (variable) = 5 ((gig of data))
Step-by-step explanation:
20x+5y=55 (7 gigs)
For a direct variation, f(x) = kx. Therefore, for f(x) = 30x, constant of variation (k) = 30.
Brother's weight * 5/8 = 110
Brother's weight * 5/8÷5/8 = 110÷ 5/8
Brother's weight = 176
