K = 4

12k + 30 - 3k = 66

9k + 30 = 66

9k = 36

k = 4

convert the mixed numbers to improper fractions. this will get you one step closer to finding the unit rate
Kaylis [27]
It means for example instead of writing 2 2/5 You would write 12/5
You can find out an improper fraction by simply multiplying the denominator by the front number and adding the answer to you numerator
So, 2x5= 10. 10+2= 12. So 12/5

Vedmedyk [2.9K]

The temperature decreases by about 1.7° for each 1-degree increase north in latitude.

Given

Latitude and longitude describe locations on the Earth with respect to the equator and prime meridian.

The table shows the latitude and daily high temperatures on the first day of spring for different locations with the same longitude.

The first row is labeled latitude (degrees North) with entries 42, 45, 39, 35, 32, 41, 40, 33, 30.

The second row is labeled high temperature (degrees Fahrenheit) with entries 53, 51, 67, 63, 70, 58, 61, 67, 72.

<h3>What is the slope of the line?</h3>

The slope of a line in the two-dimensional Cartesian coordinate plane is usually represented by the letter m, and it is sometimes called the rate of change between two points.

  • Latitude and longitude are a system of lines used to describe the location of any place on Earth.

  • Lines of latitude run in an east-west direction across Earth.

  • Lines of longitude run in a north-south direction.

  • Although these are only imaginary lines, they appear on maps and globes as if they actually existed.

Hence, the temperature decreases by about 1.7° for each 1-degree increase north in latitude.

salantis [7]
5n-4 = 6 gives the equation for 5 times #Nathan rode less 4 miles which solves to n = 2
Nathan rode 2 miles. (5*2)-4 = 6   10-4=6 so 2 miles is right

Does anyone know how to solve this?
masya89 [10]

Answer:

b = -125/9

Step-by-step explanation:

1 + log5 ( -9b) = 4

Subtract 1 from each side

1 -1+ log5 ( -9b) = 4-1

log5 ( -9b) = 3

Raise each side to the base 5

5^  log5 ( -9b) = 5^3

This will cancel the log5

-9b = 125

Divide each side by 9

-9b/-9 = 125/-9

b = -125/9

Suppose you invest $500 in a savings account that pays 3.5% annual interest. When will the account contain at least $650?
Anvisha [2.4K]
Start with 650-500, then multiply by .035. So the entire equation would be 650-500= 150x.035= 5.25
