Answer:
x>9
Step-by-step explanation:
Tamika already has $55, which will stay the same independent of how much time passes. Since she deposits $5 per week, we can assign weeks a variable x. The amount of money in her account after x weeks is equal to 55+5x. If she must save over $100, we can create an inequality to solve for how many weeks must pass: 55+5x>100.
The question also asks to solve the inequality:
- 55+5x>100
- 5x>100-55 (Subtract 55 from each side)
- 5x>45
- x>9 (Divide each side by 5)
This solution tells us that Tamika must save for more than nine weeks to have more than $100 in her account.
lmk if i made an error, hope this helps!!

Good luck on everything
1995. 164 million
2001. 169 million
t = 2001 - 1995 = 6
169 =
![p^{6} = \frac{169}{164}= 1.0304878 \\ p = \sqrt[6]{1.0304878}](https://tex.z-dn.net/?f=%20p%5E%7B6%7D%20%3D%20%5Cfrac%7B169%7D%7B164%7D%3D%201.0304878%20%5C%5C%20%20p%20%3D%20%20%5Csqrt%5B6%5D%7B1.0304878%7D%20%20)
p = 1.00502
t 1 = 2015 - 2001 = 14
f ( t1 ) =
f (t1) = 169 * 1.0762 = 181.27
Answer: a country´s population in 2015 will be
181 million.
Answer:
17 k + -25
Step-by-step explanation:
Simplify the following:
-5 (1 - 5 k) - 4 (2 k + 5)
-5 (1 - 5 k) = 25 k - 5:
25 k - 5 - 4 (2 k + 5)
-4 (2 k + 5) = -8 k - 20:
25 k + -8 k - 20 - 5
Grouping like terms, 25 k - 8 k - 20 - 5 = (25 k - 8 k) + (-5 - 20):
(25 k - 8 k) + (-5 - 20)
25 k - 8 k = 17 k:
17 k + (-5 - 20)
-5 - 20 = -25:
Answer: 17 k + -25
