Answer:
See below
Step-by-step explanation:
25¹¹ - 5¹⁹
Convert to base 5 = (5²)¹¹ - 5¹⁹
= 5²² - 5¹⁹
Factor out the GCF = 5¹⁹(5³ - 1)
= 5¹⁹(125 - 1)
= 5¹⁹ × 124
= 5¹⁹ × 4 × 31
31 is a factor of 25¹¹ - 5¹⁹, so the expression is divisible by 31.
Answer:
$199.31
Step-by-step explanation:
To find the answer, you have to do 190 x 4.9%, which is $9.31. You can also do 190 x 4 9/10, which you need to make the 4 9/10 an improper fraction, which is 49/10. 190 x 49/10 is 9.31. 190 + 9.31 is the answer ($199.31)
Answer:
1000 : 199 : 271
Step-by-step explanation:
A rations a form of comparison between different variables or quantities.
We want to compare how much water, sucrose and saline solution are used to make the medicine.
The amount of water used is 1 L = 1000 mL
The amount of sucrose used is 199 mL
The amount of saline solution used is 271 mL
Therefore, the ratio of water to sucrose to saline solution is:
1000 : 199 : 271
This is the simplest form because 1000, 199 and 271 do not have any common factors.
first you convert to slope intercept form
3x+y = 5 is the same as y = -3x+5
x - 4y = 32 is the same as y = 4x-8
then you graph
(starting with the y-intercepts as your first points)
the point where the two lines intercept is your solution.
I would go with D. 2x^2+3/2x-5
