85C - 170A = 306 ---------- (1)
255 + 85B = 714 ------------(2)
(1) + (2):
85C + 85A + 85B = 1020
Divide by 85 through:
A + B + C = 12
The total of A, B ad C is 12.

Find average :
-------------------------------------------------------------
The average of A, B and C is 12 ÷ 3 = 4
-------------------------------------------------------------
Answer: The average of A, B and C is 4.

Answer:
2x - y = 8
Step-by-step explanation:
2x - y = 8 does not belong with the other equations because C. the equation is in standard form
Answer:
48x + 216 square inches.
Step-by-step explanation:
Area is length X width.
Area is (4x + 18)(12).
in 4x + 18, 18 comes from adding the three 6 in.
We have no values for "x", so expand the equation and simplify.
(4x + 18)(12)
= 48x + 216
Answer:
Brad needs 37.68 ft of plastic edging to enclose the flower garden, in terms of "pi" it is 12π only.
Step-by-step explanation:
Given:
Diameter of the circular flower garden = 12 ft
We have to find the measure of the plastic edging Brad need to have.
So,
We have to find the length of the edge of the circular garden for circular object the measure of its length has a special name we call it circumference.
And it is very well known to us that:
For any circle the ratio of its circumference and its diameter is equivalent to pie (π) which is equal to 3.14
Then,
⇒
In the above question we have to find the measure of its circumference.
⇒
⇒
⇒ ft
⇒ Or
⇒
⇒ ft
Brad needs 37.68 ft of plastic edging to enclose the flower garden, in terms of "pi" it is 12π only.
