Solve the following systems of equations without graphing 5x + 10y = 30 -5x +15y = 20

galben [10]

Answer:

(2, 2)

Step-by-step explanation:

In this case, elimination would be the most efficient means of solving.

Simply, add the two equations, and you will be left with only one variable to solve for. (In this case y) You are then able to take your solution and plug it into an equation and solve for x, therefore giving you their intercept.\

5x + 10y = 30

-5x + 15y = 20

(x's cancel) 25y = 50

25y = 50

y = 2

5x + 10(2) = 30

5x + 20 = 30

5x = 10

x = 2

The solution to this equation is (2, 2)

$75 before tax. Disc: 10% Tax: 7%, Tip: 20% what’s the total?

ololo11 [35]

Answer:

$102.75

Step-by-step explanation:

Given the following question:

We are given a cost of 75 dollars and are being asked to find the total cost after adding a tip, tax, and disc to the cost. To find this answer we will use the formula to calculate percentages making sure we use 75 as our base for each addition to our total cost.

Formula to calculate percentages:

$\frac{p\times n}{100}$

First the disc:

$\frac{10\times 75}{100}$
$10\times75=750$
$750\div100=7.5$
$=7.5$

Next the tax:

$\frac{7\times75}{100}$
$7\times75=525$
$525\div100=5.25$
$=5.25$

Last but not least the tip:

$\frac{20\times75}{100}$
$20\times75=1500$
$1500\div100=15$
$=15$

Finally add:

$75+7.50+5.25+15=102.75$
$=102.75$

The total cost after adding the disc, tax, and the tip will be "$102.75."

Hope this helps.

What is the area of this figure? 56? 90? 146? 216?

Taya2010 [7]

The area of the trapezoid is (1/2)(4+14)(10) = (5)(18) = 90.
The area of the triangle is (1/2)(14)(8) = 56.
Adding these, we get 56 + 90 = 146.
