Answer:
<h2>

</h2>
Step-by-step explanation:
To find y when x=4, we must first find the relationship between them
The statement
y varies directly with x is written as
<h3>

</h3>
where k is the constant of proportionality
From the question
when y = 1/5
x = 3
Substitute the values into the above formula and solve
That's
<h3>

</h3>
So the formula for the variation is
<h3>

</h3>
From the question
when x = 4
<h3>

</h3>

Triangle ABC is an equilateral triangle. it is equiangular. Therefore, the value of x is 60 degrees.
<h3>What is an equilateral triangle?</h3>
An equilateral triangle is a triangle that has all it sides and angles equal to each other.
An equilateral triangle is equiangular.
Therefore, the angles of an equilateral triangles are equal to 60 degree each.
Recall the sum of an angle of a triangle is 180 degrees.
Therefore, the value of angle x is 60 degrees.

4a-[7-2(a+6)+5a]
4a-[7-2a-12+5a] :you distribute the 2 to the a and the 6
4a-[-5+3a] :you combine like terms(the 7&(-12) and the 2a&5a
4a+5-3a :you distribute the (-) to make +5 and -3a
