start by doing some factoring
<span><span><span>(x+5)(x−1)</span><span>(x−1)(5x−3)</span></span>×<span><span>4(5x−3)</span><span>(x−11)(x+5)</span></span></span>
cancel common factors and then see whats left...
So you cancel (x+5) and 4(5x-3)?
We already know that 22 = 1, but we need to find how many pages she'd read if it were 114.5 hours: 114.5 x 22 = 2519.
Hope this helps,

ANSWER: 1.562
move the decimal point of 0.0034 to the right to make it a whole number which is 34. Then multiply 34 times 430 which is 15,620.
move the decimal point (which is at the end) 4 times to the left
the answer will be 1.562
Slope intercept form: y=mx+b
12x+3y=-18 subtract 12x on both side
3y=-12x-18 divide both sides by 3
y=-4x-6 is the answer
Answer:
(4, - 6 )
Step-by-step explanation:
7x - y = 34 ( multiply through by - 1 )
- 7x + y = - 34 ( add 7x to both sides )
y = 7x - 34 → (1)
2x + 3y = - 10 → (2)
substitute y = 7x - 34 into (2)
2x + 3(7x - 34) = - 10
2x + 21x - 102 = - 10
23x - 102 = - 10 ( add 102 to both sides )
23x = 62 ( divide both sides by 23 )
x = 4
substitute x = 4 into (1)
y = 7(4) - 34 = 28 - 34 = - 6
solution is (4, - 6 )
