So whatever happened does not matter, They are only asking the volume of liquid left in A at the end. Therefore :
Calculation :
B + 120 = 4A
B = 4A - 120 ---------- 1
A - 120 = B ------------ 2
Subtract 2 from 1
B - B = 4A - 120 - A - 120
0 = 3A - 240
240 = 3A
240 ÷ 3 = A
8 = A
Answer :
A = 8
Answer:
no real solution
Step-by-step explanation:
Answer:
(C)51.4 degrees
Step-by-step explanation:
The sum of the exterior angle of a polygon is 360 degrees. (one complete revolution).
Given a regular polygon, the sum of each exterior angle is calculated using the formula:
where n is the number of sides.
The regular polygon shown made by the ant has 7 sides.
Therefore:
Each exterior angle 
Therefore:
The value of A correct to 1 decimal place is 51.4 degrees.
The correct option is C.
Answer:
x = 0
Explanation:
Equation: −(5x−8)=3(x−2)+14
Step 1: Simplify both sides of the equation.
−(5x − 8) = 3(x−2) + 14
−5x + 8 = (3)(x) + (3)(−2) + 14 (Distribute)
−5x + 8 = 3x + −6 + 14
−5x+8=(3x)+(−6+14)(Combine Like Terms)
−5x + 8 = 3x + 8
−5x + 8 = 3x + 8
Step 2: Subtract 3x from both sides.
−5x + 8 − 3x = 3x + 8 − 3x
−8x + 8 = 8
Step 3: Subtract 8 from both sides.
−8x + 8 − 8 = 8 − 8
−8x = 0
Step 4: Divide both sides by -8.
-8x / -8 = 0 / -8
x = 0
A) P = -3, G = 3, -G = -3, P = -G.
