Answer:
5x+3
Step-by-step explanation:
Rewrite the expression to 20x^2-3x-9/4x-3
Factor 20x^2+12x-15x-9/4x-3
Factor 4x*5x+3-3(5x+3)/4x-3
Factor (5x+3)*(4x-3)/4x-3
Solution then becomes 5x+3 as stated above

What is the measure of angle Y?
Answer:
Y=70
Step-by-step explanation:
For starters, all the interior angles inside a pentagon add up to 540. This number can be found for any polygon with the forumla (n-2)180. N stands for the number of sides and then you plug it into the equation. For instance, if we wanted to find it for a triangle, we would see that the triangle has three sides and plug it into the formula. (3-2)180 which equals 180. For the ptenagon we take the fact that it has five sides and add it into the equation. (5-2)180 which equals 540. So now that we know all the interior angles are supposed to add up to 540, we can find the value of Y. So let's start by finding what amount we already have.
T=110
A=150
D=120
O=90 (this is beacuse of the right angle square placed which equals 90 degrees)
All those angles add to 470 degrees. So to find the last angle, you would subtract our total of 470 from our interior angle total of 540.
540-470=70
Y=70.

A bag has 2 blue, 3 red, and 5 yellow tiles. Find the probability of picking a blue tile.
Given:
A bag has 2 blue, 3 red, and 5 yellow tiles.
To find:
The probability of picking a blue tile.
Solution:
We have,
Number of blue tiles = 2
Number of red tiles = 3
Number of yellow tiles = 5
Total number of tiles = [tex]2+3+5[/tex]
= [tex]10[/tex]
Now, the probability of picking a blue tile is
[tex]P(\text{Blue})=\dfrac{\text{Number of blue tiles}}{\text{Total number of tiles}}[/tex]
[tex]P(\text{Blue})=\dfrac{2}{10}[/tex]
[tex]P(\text{Blue})=0.2[/tex]
Therefore, the probability of picking a blue tile is 0.2.

Step-by-step explanation:
15 less than 2 times a number is the same as 7 more than half of the number. what is the number?
Answer:
x = 14 and 2/3
Step-by-step explanation:
Make an equation where x is the number.
2x - 15 = 7 + 1/2x
Then, solve the equation.
multiply both sides by 2 to get rid of the fraction
4x - 30 = 14 + x
subtract x from both sides
3x - 30 = 14
add 30 to both sides
3x = 44
divide both sides by 3
x = 14 and 2/3

Three of the angles of a
quadrilateral measure 36', 72, and
144. Which one of the following could
be the measure of the fourth angle
of the quadrilateral?
Answer:
Angles of a quadrilateral add up to 360
so x+36+72+144=360
x+252=360
x=360-252
x=108

6 laps = 5 minutes
18 laps = _ minutes
6*3= 18
5*3=15
Answer:
15 min
Step-by-step explanation:
6 laps in 5 minutes
if your trying to find how many min it takes for laps you can do
6 + 6 + 6 = 18 or 6*3 = 18
add a 5 for every 6 you see
so 5 + 5 + 5 = 15 or 5*3= 15
it takes your friend 15 min to complete 18 laps
Hope this Helps!!!
