(2x-3)(x+5)=0 is the factored form
x=3/2, x=-5
So r=1.5 and s=-5
r-s=1.5-(-5)
r-s=6.5
Answer:
63 weeks
Step-by-step explanation:
252 - 3x = 378 - 5x
+ 5x +5x
Add 5x to both sides
252 + 2x = 378
-252 - 252
Subtract 252 from both sides
2x = 126
Divide 2 from both sides
x = 63
Check you work by plugging 63 where the x is
252 - 3(63)
252 - 189 = 63
378 - 5(63)
378- 315 = 63
Answer:
1500066.66
Step-by-step explanation:
Given: 
Now, simplifying it.
Using PEDMAS in solving the expression
First opening the parenthesis
= 
Next dividing the number
as per law of indices, 
= 
= 
= 
Next multiplying the number as per PEDMAS
as per law of indices, 
= 
= 
= 
Next dividing the number as per PEDMAS
= 
Next multiplying the number as per PEDMAS
= 
Now adding the number
= 1500066.66
<span>a/b = 3/5 ----- a = (3b)/5
a + b = 136 --- (3b)/5 + b = 136
3b + 5b = 680
8b = 680
b = 85
a = (3b)/5 = (3 * 85)/5 = 51
a = 85 and b = 51</span>
