Answer:
x = 7.416666667
Set everything equal to 180 (the total # of degrees in a triangle)
180 = 14x-13 + 4x+13 + 6x+2
Combine the variables
180 = 24x - 13 + 13 + 2
Do the math
180 = 24x +2
178 = 24x
x = 7.416666667
C. -7
Solve for n by simplifying both sides of the equation, then isolating the variable.
2 quarters, 3 dimes and 4 nickels
the thickness in scientific notation is:
4.3* 10⁻³ inches
<h3>
How to write the thickness in scientific notation?</h3>
Here we know that the thickness of a dollar bill is 0.0043 inches.
Now, scientific notation refers to the notation where we have a single digit at the left of the decimal point, and the order of the number is defined by a factor of a power of 10.
To write our number in scientific notation we need to count the number of zeros that we have before the first non-zero decimal, and we can see that it is equal to 3.
Then we can move all the digits 3 units to the left, and add a factor 10⁻³ to correct that, then we will get:
0.0043 = 4.3* 10⁻³
From this, we conclude that the thickness in scientific notation is:
4.3* 10⁻³ inches

The amount increased 4% from last year.
Step-by-step explanation:
Given,
Average cost last year = $625
Average cost this year = $650
