1. mean number read by Ethan is (39+ 60 + 29 + 29 + 45) / 5 = 202/5 = 40.4
2. Mean number by Daniel = (34 + 29 + 54 + 43 + 24) = 184 / 5 = 36.8
Combine the like terms (3x plus 9x) = 12x
(11 plus -19) = -8.
12x -8
divide both sides by 12 and you will have your answer!
The approach is to first find the value of constant of proportionality 'k'.
As y varies directly with x²
So we have
y = k x².
Now when x = 6 , y = 72
Substituting the values we get
72 = k (6)²
72 = 36 k
Dividing by 36 on both sides
2 = k
So (1) becomes
y = 2 x²
Now we need to find y when x = 14
Substituting the values in (2) we get
y = 2 ×(14)²
y = 2 × 196
y = 392
Hence y = 392 when x = 14.
Answer:
the quotient is another word for division so the quotient in this equation is:
2x − 3 x ÷ 7 x2
Answer:
38 is the correct solution
