Xelga [282]3 years ago
8 0

Answer:

Step-by-step explanation:

Start by removing the brackets.

Left Brackets

30(1/2 x - 2)

30*1/2 x - 30*2

15x - 60

Right Bracket

40(3/4 y - 4)

40*3/4 y - 4*40

10*3 y - 160

30y - 160

Now put these 2 results together.

15x - 60 + 30y - 160     Combine the like terms.

15x + 30y - 220            That's one answer Others are possible.

Which object has the same y-intercept as a function y=2/3x-3?
Licemer1 [7]

The 4th option.

The values with no x or y attached are the y intercept

6x - 7y = 21

Subtract 6x from both sides

6x - 7y - 6x = 21 - 6x

-7y = 21 - 6x

Divide both sides by - 7

-7y/-7 = 21/-7 - 6x/-7

Y = -3 +6x/7


The why intercept, -3 is the same as the one in the question

How to convert 3.248 repeating decimal with 48 repeating into a simplified fraction
Sonja [21]

Answer:

x=\frac{536}{165}

Step-by-step explanation:

Let X be the value of 3.2484848.... infinite times

Multiply by 100

x=3.24848....\\100x = 324.8484.....

Subtract to get

100x-x = 324.8484...-3.248484....\\99x = 321.60\\x=\frac{321.6}{99} \\x=\frac{1072}{330} \\x=\frac{536}{165}

Thus the number 3.248 repeating decimal with 48 repeating in fraction form is

\frac{536}{165}
