Answer:
y = 14.5
Step-by-step explanation:
given that y varies directly as x
mathematically,
y ∝ x
y = kx .............................................. where k is the constant of proportionality.
k = y /x
given that
y = 79
x = 49
k = 79/49
k = 1.61
to find y when x = 9
from
y = kx
y = 1.61 × 9
y = 14.5
therefore the value of y when x = 9 in ths variation is evaluated to be equals to 14.5
6x + (-9) or 6x - 9
Try looking at the terms for the same things. Such as the variable like X and the negatives add together and make a negative

Answer:
80
Step-by-step explanation:
because you have to do (11+11)+(9+9)+(10+10) and you would get 22,18,20 and add all together and get 80 because you have to do 22+18=40 then add the remaining 20 and you would get 80
