What is the Value of x+y ? PLZ Help ASAP

Natalija [7]

ANSWER

$x + y = 60$

EXPLANATION

Method 1

Vertically opposite angles are equal, therefore

$3x + 55 = 85$

This implies that,

$3x = 85 - 55$

We simplify to get,

$3x = 30$

Dividing through by 3 gives,

$x = 10$

Also,

$2y - 5 = 95$

This implies that,

$2x = 95 + 5$

We simplify the right hand side to get,

$2x = 100$

We divide both sides both sides by 2 to get,

$x = 50$

$x + y = 50 + 10$

$x + y = 60$

Method 2

Angles on straight line sums to 180°.

$2y-5+85=180$

This implies that,

$2y+80=180$

$2y=180-80$

$2y=100$

$y=50$

Also,

$3x+55+95=180$

$3x+150=180$

$3x=180-150$

$3x=30$

$x=10$

$x+y=50+10$

$x+y=60$

(1,9) m=-3 in point slope form

Marysya12 [62]

Use the given slope and point and put it into the point-slope formula
y - y1 = m ( x - x1 )

1 is your x value (x1) and 9 is your y value (y1). M = -3

In point slope form, the answer is
y - 9 = -3 ( x - 1 )

You want to buy a jacket that is $75. Today it is marked down 33 one-third percent. The sales tax is 8%. How much will you pay?

lara [203]

Answer:

$54

Step-by-step explanation:

Price of jacket = $75

Markdown = 33.33...%

Sales tax = 8%

First we have to find the price of the jacket after the markdown.

75-33.33(75)

75-(25)

New price of jacket = $50

Now to calculate the price with sales tax.

50+0.08(50)

50+(4)
