Given data;

No of blue marbles= 5,

No of red marbles=6

No of green marbles=2

Total no of ball  = 5+6+2

Total no of ball  = 13

What is the slope of the line represented by the equation y- 6 = 2(x+3)?
OLga [1]
*Remember that slope : is y=mx+b
And m is slope and b is the y-intercept -

In this equation y-6=2(x+3)
m is 2 because if u multiply 2 to (x+3) it will become 2x+6
since m is 2 and b is 6
The slope is 2
And the y-int. is 6

So the slope is 2.

I need to write a decimal where the value of a digit is 1/10 as much as a digit in another place
KengaRu [80]
1/10 is the same as saying 10 times less

Refer to the diagram below
The digit as the first decimal place is worth 1/10
The digit as the second decimal place is worth 1/100 which is 1/10 worth the digit as the first decimal place

Example of two decimal numbers:

2.56 and 2.68

The digit 6 in 2.56 is 6/100
The digit 6 in 2.68 is 6/10

The digit 6 in 2.56 is 1/10 as much as the digit 6 in 2.68
