y= 1/3x-10
if x= 12
Y=1/3(12)-10
Y= 12/3 -10
divide 12/3 by 3
12/3 = 4
Y= 4-10
Y= -6
I hope that's help and please if you have questions just let me know !
Fraction of students left-handed:
There are more right-handed students
Step-by-step explanation:
To solve the problem, we call:
the fraction of students in the class that are left-handed
the fraction of students in the class that are right-handed
We know that:
is the fraction of students which are left-handed
we can convert this value into fractional form dividing by 100:
Simplifying by 4,
We also know that
, because the fraction of students that are either left or right-handed must be 100%
Therefore, the fraction of students that are right-handed is
Therefore, there are more right-handed than left-handed students.

Answer:
The recipe calls for 4/3 cups of oatmeal and 9/2 cups of flour.
If we convert them to a common denominator, we have 8/6 cups of oatmeal and 27/6 cups of flour, so, the ratio is 8:27.
If you use 6 cups of oatmeal and 9 cups of flour, the ratio will become 2:3 and will no longer be proportional
Let the first term, common difference and number of terms of an AP are a, d and n respectively.
Given that, 9th term of an AP, T9 = 0 [∵ nth term of an AP, Tn = a + (n-1)d]
⇒ a + (9-1)d = 0
⇒ a + 8d = 0 ⇒ a = -8d ...(i)
Now, its 19th term , T19 = a + (19-1)d
= - 8d + 18d [from Eq.(i)]
= 10d ...(ii)
and its 29th term, T29 = a+(29-1)d
= -8d + 28d [from Eq.(i)]
= 20d = 2 × T19
Hence, its 29th term is twice its 19th term
Answer:
Proved below.
Step-by-step explanation:
a9 = a1 + 8d = 0 where a1 = first term and d = common difference.
we need to prove that
a1 + 28d = 2(a1 + 18d
simplifying:-
a1 + 36d - 28d = 0
a1 + 8d = 0 which is what we are given.
Therefore the proposition is true.
Answer:
The novel has 180 pages.
Step-by-step explanation:
108 pages is 60% of the novel.
108 / 3 = 36.
20% of the novel is 36 pages.
36 * 5 = 180 pages
