1 answer:
Answer:
C
Step-by-step explanation:
If a line is parallel to a side of a triangle and it intersects the other 2 sides then it divides those sides proportionally.
BE is such a line , then
=
( substitute values )
=
( cross- multiply )
9 BC = 46 ( divide both sides by 9 )
BC ≈ 5.1 ( to the nearest tenth )
Then
AC = AB + BC = 9.2 + 5.1 = 14.3

A quotient is the result of a division.
Let the unknown number be x.
We translate the problem into an equation, piece by piece.
<span>"quotient of a number and seven" ----> x/7
</span>
<span>"12 less than the quotient of a number and seven" ----> x/7 - 12
The word "is" means "="
x/7 - 12 =
All the above is -2, so it equals -2.
x/7 - 12 = -2
First, add 12 to both sides and simplify.
