The 2 equations are
18.20x+19.50y=230.10
and
x+y=12
where x is the months of original cost and y is months for new cost. Since you know that you paid for one year (12 months) you can make the second equation. Then you want to substitute the first equations x by making the second equation
x=(12-y)
18.20(12-y)+19.50y=230.10
218.40-18.20y+19.50y=230.10
1.30y=11.70
y=9
so that means you had the original rate for 3 months and the new one for 9 months

A Woman Leaves Home And Walks 3 Mi. West, And Then 2 Mi. South. What Is The Magnitude Of Her Displacement, and what direction mu
mojhsa [17]

Answer: 4 Mi Northeast

Step-by-step explanation:

  • west points left on a compass, and x points left on a graph so the value becomes x ⇒ ( 3x )
  • south points down on a compass, and y points down on a graph so the value becomes y ⇒ ( 2y )

Equation: V=3x +2 y

Solving Steps:

1. take the sum of the square of each vector component

3^2 + 2^2 = 9 + 4 = 13

2. take the square root of the result from from the last step

\sqrt{13}=3.60555127546

3. round to nearest whole number as told in your question

60555127546 ⇒ 4

4. find direction to go with number

- opposite of west is east

- opposite of south is north

direction is northeast

========================

ans = 4 Mi Northeast

Which of the following equations represents a line parallel to 4x - y = -5?
pickupchik [31]
Correct answers are A, C and D.

Parallel lines have equal slopes.

4x - y = -5 ⇒ y = 4x + 5 ⇒ m = 4
8x - 2y = -10 ⇒ 4x - y = -5 ⇒ m = 4
4x + y = -2 ⇒ y = -4x - 2 ⇒ m = -4
4x - y = 2 ⇒ y = 4x - 2 ⇒ m = 4
2x - \frac{1}{2}y = -\frac{5}{2}\Rightarrow4x-y=-5 \Rightarrow y=4x+5 \Rightarrow m=4

An online retailer collects 7% sales tax. If the sub total of the purchase is $76.00, then how much is collected for sales tax?​
jok3333 [9.3K]

The collected tax on purchase of $76.00 is $5.32

Further explanation:

The sales tax is calculated on the total sales by the formula

Tax = total * \frac{7}{100}

Given

Total purchase = $76.00

Percentage of tax = 7%

So,

Putting the values in the formula

Tax\ amount = 76.00 * \frac{7}{100}\\= 5.32

So, the collected tax on purchase of $76.00 is $5.32
