Turn .055 into fraction
Slav-nsk [51]
Write 0.055 as
0.055
1

Multiply both the numerator and denominator by 10 for each digit after the decimal point.

0.055
1

The factors of 55 are: 1 5 11 55
The factors of 1000 are: 1 2 4 5 8 10 20 25 40 50 100 125 200 250 500 1000
The Greatest Common Factor (GCF) for both 55 and 1000 is: 5
Now to reduce the fraction we divide both the numerator and denominator by the GCF value.

=
0.055 x 1000
1 x 1000
=
55
1000


In order to reduce the fraction find the Greatest Common Factor (GCF) for 55 and 1000. Keep in mind a factor is just a number that divides into another number without any remainder.

Answer ( 55/1000
= 11/200)

Please help. I’ll mark you as brainliest if correct!
yKpoI14uk [10]

Answer:

When x = -1/4 and when x = -15/4

Step-by-step explanation:

The x intercept will be when f(x)=0, so

0 = 4|x+2| -7

7 = 4|x+2|

|x+2|=7/4 here you have to cases

case 1

x+2=7/4

x=7/4-2

x=-1/4 = -0.25

case 2

x+2 = -7/4

x = -2-7/4

x = -15/4 = -3.75
