If phone A, length is 5.4 in and it’s width is 2.6 in and phone B, length is 6.21 in. and the lengths and widths of the two cell phones are proportional what is the width of phone B

let the width be x

5.4/2.6 = 6.21/x

5.4x = 16.146

x = 16.146/5.4

x= 2.99 cm

Step-by-step explanation:

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
