Answer:you should multiply
Step-by-step explanation:
Because 3/4x12=9
Answer: y = 36x
Step-by-step explanation: Given that x and y vary directly then the equation relating the is
y = kx ← k is the constant of variation
To find k use the condition x = , y = 12, then
k = = = 12 × 3 = 36
y = 36x ← equation of variation
An expression with 18 and 20.
An expression does not have an equal sign.
18+20
Hope I helped.
Step-by-step explanation:
Mean= The data points that add up, or, the sum of all data points, divided by the number of data points, will give you the answer,
So
20+50+30+40+60+80 would be
100+40+60+80 which is
200.
Since there are 6 numbers in the problem, we do
200/6
which will give us
33.33 etc. (33.3333333333 on and on forever)
