Gnesinka [82]3 years ago
6 0

Answer:

645/100 = 129/20 or 6.45

645/50 = 129/10 or 12.9

48.6/30 = 1.62

48 divided by x = 48.6/x

Step-by-step explanation:

645/100

Factor the number:

= 5*129/100

Factor the number:

= 5*129/5*20

Cancel the common factor:

= 129/20

645/50

Factor the number:

5*129/50

Factor the number:

5*129 / 5*10

Cancel the common factor:

= 129/10

48.6/30

Write the problem in long division format

Multiply the quotient digit (1) by the divisor (30)

Subtract 30 from 48

Add a decimal and bring down the next number

Divide 186 by 30 to get 6

Continue...A few steps later...

Subtract 60 from 60

Solution is 1.62

48.6/x

Re-write division as a fraction:

48.6/x

14. What is the slope and y-intercept of the equation 5(y + 3) + 6(x - 3) - 2 = 0?
Alexxandr [17]

Step-by-step explanation:

5(y + 3) + 6(x - 3) - 2 = 0 \\  \\ 5y + 15 + 6x - 18 - 2 = 0 \\  \\ 5y + 6x + 15 - 20 = 0 \\  \\ 5y + 6x - 5 = 0 \\  \\ 5y =  - 6x + 5 \\  \\ y =  -  \frac{6}{5}  x+  \frac{5}{5}  \\  \\ y =  -  \frac{6}{5}  x+  1 \\ equating \: it \: with \\ y = mx + c \\ \\  slope \: (m) =   -  \frac{6}{5}  \\  \\ y - intercept \:( c )= 1
