The value of x would be 5 for the model 2x+4.

Rearrange unknown terms to the left side of the equation,
= > 2x-3x = -1 - 4

Combine like terms= -x = -1-4

By calculating the sum or difference : -x = -5

Lets divide both sides of the equation by the resulting coefficient 5
So x = 5

A disc has a diameter of centimeters while a mini disc has a diameter of centimeters. Write the ratio of the mini disc diameter
Dafna1 [17]

Answer:

2 : 3

Step-by-step explanation:

A disc has a diameter of 21 cm while a mini disc has a diameter of 14cm. Write the ratio of the mini disc diameter to the disc diameter.

Answer: Let the diameter of the mini disc be d_1 while the diameter of the disc be d_2. To get the ratio of the mini disc diameter to the disc diameter, we just simply have to divide the diameter of the mini disc by the diameter of the disc and then represent the fraction in ratio form. The ratio of the disc diameters is given by:

Ratio of the mini disc diameter to the disc diameter = Diameter of mini disc / diameter of disc

Ratio of the mini disc diameter to the disc diameter = \frac{14}{21}=\frac{2}{3}

Ratio of the mini disc diameter to the disc diameter = 2 : 3
