1 pt; or 1 pint seems most reasonable here.
Hey. Good afternoon.
120$ --- 80%
x --- 100%
80x = 12000
x = 12000/80
x = 150$
Sorry my bad english, i'm Brazilian.
Answer:
(2a - 5) • (3a - 2)
step by step explanation:
Step-1 : Multiply the coefficient of the first term by the constant 6 • 10 = 60
Step-2 : Find two factors of 60 whose sum equals the coefficient of the middle term, which is -19 .
-60 + -1 = -61
-30 + -2 = -32
-20 + -3 = -23
-15 + -4 = -19 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -15 and -4
6a2 - 15a - 4a - 10
Step-4 : Add up the first 2 terms, pulling out like factors :
3a • (2a-5)
Add up the last 2 terms, pulling out common factors :
2 • (2a-5)
Step-5 : Add up the four terms of step 4 :
(3a-2) • (2a-5)
Which is the desired factorization
Final result :
(2a - 5) • (3a - 2)
The measure of each of the angles ∠P,∠Q,∠R, ∠S are 45°,72°,135° and 98° respectively.
<h3>What is quadrilateral ?</h3>
A quadrilateral is a polygon having four sides. The measure of the opposite angle of quadrilateral inside circle is 180°.
From the figure:
∠P=x+15
∠Q=3x-8
∠R=?
∠S=3x+8
∠Q+∠S=180
3x-8+3x+8=180
6x=180
x=30°
∠P+∠R=180°
x+15+∠R=180
30+15+∠R=180
∠R=180-45
∠R=135°
∠P=30+15=45
∠Q=3x-8=3(30)-8=72
=135
∠S=3x+8=3(30)+8=98
Hence,the measure of each of the angles ∠P,∠Q,∠R, ∠S are 45°
,72°,135° and 98°.

Let the number be X
20% of X = 9
20/100 * X =9
1/5 *X =9
X/5 =9
X = 9*5=45
the number is 45
