Step-by-step explanation:
Distribute into 5x² into (3x +2).
The simplified expression is <em>15x³ + 10x²</em>
1.50x.20=.30
It's 30 cents

Answer:
0
Step-by-step explanation:
Given

Determine its new position
Because the ring was initially below the surface of the pool;
Its initial position is
Taking it to the surface of the pool;
It means, the ring travels a distance of:
It's final position is the summation of its initial position and distance travelled;
<em>Hence, 0 represents its new position with respect to the surface of the water</em>
So here you're using system of equations. You can solve systems by graphing, elimination, or substitution. Ill use substitution. First lets solve for x. take the second equation and add y to both sides to get x by itself:
x - y = 75
x = y + 75 now plug y+75 in for x in the first equation
x + y = 743
(y +75) +y = 743 solve for y
2y +75 = 743 subtract 75
2y = 668 divide both sides by 2
y = 334
now plug this into any of the 2 equations to solve for x i chose the second one
x - y = 75
x - 334 = 75 add 334 to both sides
x = 409
This means x, sold before the tournament is 409 and y, sold at the door is 334. That means the assistant is wrong and accidentally flipped the two answers
