The answer is 6. Plug in 3 for every x there is in the equation.
Changing percent to fraction is an easy thing.
Here is how:
1. Simply put the given number over 100. (Let us have 2%). Drop the percent sign.
2% becomes <u> 2 </u>
100
2. Reduce the fraction into its lowest term.
In reducing its lowest term, we should find their GCF first as their divisor.
2 = 1, 2
100 = 1, 2, 4, 5, 10, 20, 25, 50, 100
Their Greatest Common Factor (GCF) is 2.
3. Divide evenly.<u>
2 </u>÷ <u> 2 </u> = <u> 1 </u>
100 2 50
So, 2% is 1/50 when changed into fraction.
Answer:
2/9
Step-by-step explanation:
5 dimes and 5 pennies = 10 coins
P( dime) = number of dimes / total
=5/10 = 1/2
keep the dime
4 dimes and 5 pennies = 9 coins
P( penny) = number of penny / total
=4/9
P( dime, keep, penny) = 1/2 * 4/9 = 2/9
Answer:
y = -4x + 11
Step-by-step explanation:
Equation of a line is
y - y_1 = m ( x - x _1)
We are provided
Slope = m = -4
Points = (x _1 , y_1) = (2, 3)
Insert the values
y - y_1 = m( x - x_1)
y - 3 = -4(x - 2)
Open the bracket with -4
y - 3 = -4x + 8
y - 3 -8 = -4x
y - 11 = -4x
Following this equation of a line
y = mx + C
y - intercept point y
m - slope
x - intercept point x
C - intercept of the line
y - 11 = -4x
y = -4x + 11
Therefore, the equation of the line is
y = -4x + 11
