Answer:

y = -1, x = -2

Step-by-step explanation:

First, multiply the top equation by 2 to make 3x become 6x:

6x - 8y = -4

Second, multiply the bottom equation by 3 to make -2x become -6x:

9y - 6x = 3

Add the two equations together, and you get:

y = -1

Plug in y as -1 into the first or second equation:

3x - 4(-1) = -2

OR

3(-1) - 2x = 1

x = -2

Answer:

2. 3-(-2)-(+5)

⇒3-(-2)-(+5)= 3+2-(+5) = 5-(+5)  =  5-5  = <u>0</u>

3. -(-3-6)-(-4+8)

⇒ -(-9)-(-4+8) = 9-(-4+8)  =  9-4 =5

4. -8-(-3-2)

⇒ -8-5=-13

5. -(-(-5))+7

⇒ -5+7 = 2

6. -(-(-8)+3)

⇒ -(11) = -11

7. -(-6-(-3+1))

⇒6-(-3+1) = 8

8. 1-(14-(11-7))

⇒ 1-(14-4) = 1-10 = -9

A clerk is marking up merchandise 34%. The original price of an item is $455. What will be the retail price?
Galina-37 [17]
Take the orginal price and multiply it by 1.34.
455 * 1.34 = $609.70 in retail.

The longer way would be to take 34% of 455 and then add it to 455.

In Kite KLMN, find the measure of
Degger [83]

Answer:

M = K =

<h3>101°</h3>

Step-by-step explanation:

M = K, because it's a kite.

  • Kite has 2 angles on the left and right, each with the same size,
  • The kite also has different angles at the other angle points.

(Addition of kite angles result in 360°)

Therefore

360 = 63 + 95 + 2M

2M = 360-63-95

2M = 202

M = 202÷2

M = K = 101°

The size of each angle M and angle K = 101 degrees.
