Answer:
5(5x+2) (x-1)
Step-by-step explanation:
25x^2 -15x -10
factor out a 5
5(5x^2 -3x-2)
5(5x+2) (x-1)
1.65 + 0.85x= $20
0.85x=$18.35
x=21 10/17
first you write the equation
then you have to subtract 1.65 from the equation but you also have to subtract it from 20
then you divide 0.85 from 0.85x and from the 18.35 left over from subtracting 1.65 from 20
then you should get x=21 10/17 (simplified) but the decimal form is a ongoing fraction so you can just round it up to the nearest hundredth

Answer:
P(rolling a multiple of 3)= 1/3
Step-by-step explanation:
Multiples of 3 in between 1-6 ( there are six numbers on a dice, from one to six) include 3 and 6. These give you two out of six outcomes with multiples of 3. Probability of an outcome is calculated by
(number of favorable outcomes/all possible outcomes)
There are only two favorable outcomes in this event, 3 and 6.
And there are 6 outcomes due to there being 6 sides on a dice.
Substitute the numbers in to get (2 favorable/6 possible) >> (2/6)
then simplify by dividing top and bottom number by two to get (1/3)
If you are rolling it one time, then there is no need to do additional work.
What sup hows it going there
