Ivenika [448]

The value of the expression, 5x^2 - 4, when x = 2 is: 16.

<h3>What is the the Value of an Expression?</h3>

To find the value of an expression, plug in the given value of the variable and solve by simplifying.

Given the expression, 5x^2 - 4, when x = 2, we would have:

5(2)^2 - 4

5(4) - 4

20 - 4

= 16

Therefore, the value of the expression, 5x^2 - 4, when x = 2 is: 16.

Tony owns a car lot. He orders cars and motorcycles at a ratio 5:2. Find an equivalent ratio if Tony ordered 25 cars. Then find
Romashka-Z-Leto [24]

Answer:

10 motorcycles and 30 cars

Step-by-step explanation:

If there are 25 cars and a 5:2 ratio, then 25/5=5, and 5x2=10, then there will be 10 motorcycles.

                   5:2

   Divide by 5 | Multiply by 2

If there are 12 motorcycles, then 12/2=6 and 6x5=30. The ratio is reversed because the translation required is reversed.

                     2:5

   Divide by 2 | Multiply by 5
