PLEASE HELP! MUCH APPRECIATED. MATH IS SO HARD :(
yulyashka [42]

Answer:

see below

Step-by-step explanation:

x+ 7.05 = 45.3

Subtract 7.05 from each side

x+ 7.05-7.05 = 45.3-7.05

x =38.25

Let x be the number

x+3.5 = -4.3

Subtract 3.5 from each side

x+3.5 - 3.5 = -4.3-3.5

x = -7.8

x is the cost of the drawing tablet

x+ 3.95 = 6.94  correct

The second equation add the total cost plus the cost of the drawing tablet  and sets it equal to the cost of the pencils.  This is not correct

6.94+x = 3.95   incorrect

If the typical balance on Lucy's credit card is $650 and the interest rate (APR) on her credit card is 18%, how much in interest
Mariana [72]

$9.75

<h3>Further explanation   </h3>

Given:  

  • The typical balance on Lucy's credit card is $650.
  • The interest rate (APR) on her credit card is 18%.

Question:  

How much in interest would you expect Lucy to be charged in a typical month?

The Process:  

This problem includes the type of determining simple interest.

\boxed{ \ I = P \times r \times t \ }  

where,

  • I = simple interest
  • P = principal (initial amount)  
  • r = annual interest rate
  • t = time (in years)

This time we will find out how much in interest we would expect to be charged in a typical month.

The data is as follows:

  • P = 650
  • r = 18% or \frac{18}{100} or 0.18  
  • t = \frac{1}{12} year  (one month)

Let us calculate how much in interest we would expect to be charged in a typical month.

\boxed{ \ = 650 \times \frac{18}{100} \times \frac{1}{12} \ }  

\boxed{ \ = 65 \times \frac{3}{10} \times \frac{1}{2} \ }  

\boxed{ \ = \frac{195}{10} \times \frac{1}{2} \ }  

\boxed{ \ = \frac{97.5}{10} \ }  

\boxed{ \ = \frac{975}{100} \ }  

Thus the amount of interest we would expect Lucy to be charged in a typical month is $ 9.75.

Notes  

We must be able to distinguish between simple and compound interest. Please learn about this in the link attached below.

What is the length of a segment in the complex plane with endpoints at 4 + 2i and 7 – 2i?
patriot [66]

The change in x, as we move from left to right, is 7-4, or +3.

The corresponding change in y is -2i-2i = -4i.

Use the Pythagorean Theorem to find the length of this line segment:


d = distance from 4+2i to 7-2i= sqrt( [3]^2 + sqrt( [-4]^2 ) = sqrt(9+16) = 25 (ans.)
