Answer:
see explanation
Step-by-step explanation:
(a)
Given y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportion
To find k use the condition when x = 3, y = 18 , then
18 = 3k ( divide both sides by 3 )
6 = k
y = 6x ← equation of proportion
(b)
(i)
when x = 12 , then
y = 6 × 12 = 72
(ii)
when y = 42
42 = 6x ( divide both sides by 6 )
7 = x
If i am doing this correct.
pick to points and use the distance formula\
Y2 - Y1
divided by
X2 - X1
so i picked the points
-2, 12
0, 3
this would mean
12-3
0-(-2)
which would be
9
2
so 9/2 it isn't possible so it would stay as 9/2 which is your answer.. C
Hope this helps.!!!!
Let the third angle = x
It would be: 35 + 45 + x = 180
80 + x = 180
x = 180 - 80
x = 100
So, your final answer is 100
Hope this helps!
Hello there!
Explanation:

You had to used least common multiple of 6 and 3.
Prime factorization of 6: 1, 2, 3, 6
3*2=6
Prime factorization of 3: 1, 3
1*3=3
Then multiply by the number
3*2=6
You can also multiply by each numerator by the same amount needed to multiply its corresponding denominator to turn it into the least common multiple is 6.
Then you had to used 4/3 multiply by the denominator and numerator by 2.
Since the denominators are equal, it combine by the fractions.
Then you can subtract by the numbers.
You had to cancel by the common factor of 3.
Answer⇒⇒⇒⇒7/2
