Answer:
x = 2
Explanation:
[tex]\frac{3x-1}{5} =\frac{x+1}{3}[/tex]
First, make sure they both have common denominators ( 15 )
5 × 3 = 15 and 3 × 5 = 15
Whatever you do to the denominator you have to apply to the numerator. So, multiply the numerator and denominator of the first fraction by 3.
[tex]\frac{3*(3x-1)}{3*5}[/tex] = [tex]\frac{3(3x-1)}{15}[/tex]
Next, multiply the numerator and denominator of the second fraction by 5.
[tex]\frac{5*(x+1)}{5*3}[/tex] = [tex]\frac{5(x+1)}{15}[/tex]
Now we have: [tex]\frac{3(3x-1)}{15} =\frac{5(x+1)}{15}[/tex]
Use distributive property on the numerators of both fractions.
[tex]\frac{9x-3}{15} =\frac{5x+5}{15}[/tex]
Since the denominators are equal we can ignore them for now and find x.
9x - 3 = 5x + 5
We need to move like terms to different sides to isolate x. First, we can subtract 5x from both sides.
9x - 5x - 3 = 5x - 5x +5
4x - 3 = 5
Then, we can add 3 to both sides to cancel out the -3.
4x - 3 + 3 = 5 + 3
4x = 8
Finally, to find x we divide both sides by 4.
4x ÷ 4 = 8 ÷ 4
x = 2

Sherry thinks 7, 7 and 12 are side lengths of a right triangle. Do you agree or disagree? Justify your reasoning. PLEASE NOW!!!! PLEASE!!!!!!
Answers
Answer:
disagree
Step-by-step explanation:
If the triangle is right, then the square of the longest side must equal the sum of the squares on the other 2 sides.
longest side = 12 ⇒ 12² = 144
7² + 7² = 49 + 49 = 98
Since 144 ≠ 98 then triangle is not right
The population of a city is growing at an uninhibited rate of 1.6% per year. The city's initial population was 125,000. How long will it take the population of that city to reach 175,000? Round to the nearest tenth.
a. 56.5 years
b. 21.0 years
c. 9.1 years
d. 37.8 years
Answers
Answer:
B
Step-by-step explanation:
First we find how much of 125000 is increasing. Once we do that, it is basically a slope intercept equation.
We know that 1.6 percent of 125000 is 2000.
We know have y=2000x+125000
There are two ways to solve this, either plug in the given values of a, b, c, and d into the equation and see if it equal 175000, or we we set the equation equal to 175000
If we do the second easiet option, we have
2000x+125000=175000 Use inverse operations
2000x=50000
x=25, or roughly option b.
If we plug in b, we get y=2000(21)+125000 or 167000
21.0 years will it take the population of that city to reach 175,000.
What is population growth rate?Population growth rate is the change in the number of individuals over a specific period of time. Population growth rate can be interpreted over any time period.
Given
Population of a city is growing at an uninhibited rate of 1.6% per year.
The city's initial population was 125,000.
Based on the given conditions
[tex]125000.(1+0.016)^{x} =175000[/tex]
⇒ [tex]125000.(1.016)^{x} =175000[/tex]
⇒ [tex](1.016)^{x} =\frac{175000}{125000}[/tex]
⇒ [tex](1.016)^{x} =\frac{7}{5}[/tex]
⇒ [tex]x=log_{1.016} \frac{7}{5}[/tex]
⇒ [tex]x=log_{\frac{127}{125} } \frac{7}{5}[/tex]
⇒ x = 21.0
21.0 years will it take the population of that city to reach 175,000.

Name a possible value for n that is a solution to 15 < n, but not a solution to n < 25.
PLEASE EXPLAIN WHY ITS THAT ANSWER
Answers
Answer:
26
Step-by-step explanation:
The number has to be greater than 15 but not less than 25 so any number that is at least 25 works.
Answer:
It would just be at least 26. Because, it's saying that n has to be greater than 15 and greater than 25. so, that the n < 25 is wrong. So i would put 26 because 15 < (is less than) 26, and 26 <(less than) 25 is wrong which is required to be an answer. So you could do 26 through infinity.
