1. 428 pages: <em>There are a total of 428 pages</em> that you can flip to.
2. 1/428: Page 45 is <em>only one page out of the total sample space</em>.
3. 1/2: Since the last page is 428, there is an even number of pages. That means that there are<em> 214 page numbers that are even</em>. <em>214/428 = 1/2</em>.
Answer:
y < 623.5
Step-by-step explanation:
Let the number be y
250yrs(1) - y < 3/5(1) + y
250 - y < 3/5 + y
combine the like terms
250 - 3/5 < y +y
250 - 3/5 < 2y
make 250 and 3/5 a single fraction first by finding the LCM of 5 and 1 which is 5. Multiply by their LCM.
(250/1)5 - (3/5)5
1250 - 3 < 2y
1247 < 2y
divide both sides by 2
y < 1247/2
y < 623.5
Answer:
-3, 4
Explanation:
x² + x - 12
<u>factorize</u>
x² + 4x -3x - 12
<u>take out common terms</u>
x(x + 4) -3(x + 4)
<u>collect into groups</u>
(x-3)(x+4)
p = -3, q = 4
Y would equal 0.375 but this decimal in fraction form would be 3/8
