The value of the x will be 25. The force involved vertically to the surface of an object per unit area is pressure.
<h3>What is pressure?</h3>
The force applied perpendicular to the surface of an item per unit area across which that force is spread is known as pressure.
The given data in the problem is;
The base of the block of metal is a rectangle of 20 cm by x cm.
The block exerts a force of 1500 newtons on the ground. The pressure on the ground is 3 newtons/cm²
The area of the rectangle;
A = L × B
A=20 × x
Hence the value of the x will be 25.

Answer:i think its 21
Step-by-step explanation:
22.5 x 21=472.5 then u have to add 27.5 so 472.5 + 27.5=500
Step-by-step explanation:
Answer:
Number of advance tickets sold = 30
Number of same-day tickets sold = 20
Step-by-step explanation:
Let,
x be the number of advance tickets sold
y be the number of same-day tickets sold
According to given statement;
x + y = 50 Eqn 1
25x + 20y = 1150 Eqn 2
Multiplying Eqn 1 by 25
25(x+y=50)
25x + 25y = 1250 Eqn 3
Subtracting Eqn 2 from Eqn 3
(25x+25y)-(25x+20y) = 1250 - 1150
25x + 25y - 25x - 20y = 100
5y = 100
Dividing both sides by 5
Putting y = 20 in Eqn 1
x + 20 = 50
x = 50 - 20
x = 30
Hence,
Number of advance tickets sold = 30
Number of same-day tickets sold = 20
When a number is raised to a negative exponent, change the exponent to a positive number and put the number and exponent under 1:
3^-2 = 1/3^2 = 1/9
Answer: 1/9
