Two stores sell the same refrigerator for the same original price. Store A advertises that the refrigerator is on sale for 15% o

ff the original price. Store B advertises that it is reducing the refrigerator’s price by $150. When Stephanie compares the sale prices of the refrigerator in both stores, she concludes that the sale prices are equal.
Let p represent the refrigerator’s original price.

Which equation models this situation?

The answer is <span>0.85p = p – 150</span>

since the refrigerator is 15% off

it is selling at 100%-15% = 85% of the original value

85% = 0.85

 so 0.85Pis one price

other store is selling at p-150

 so 0.85p = p-150

Find the area of the figure.
shutvik [7]

Answer:

The height is 57.5

Step-by-step explanation:

To find the height, you would use the equation h= 2 a/a+b

So you would insert the numbers and turn the equation into 2(6555/ 123+105)

Then you would solve.

After solving, you will find that H= 57.5

Hope this helped! If it helped please give brainliest!

What is the value of c in this linear system? <br> A) 1<br> B) -3<br> C) -1<br> D) 2
Alika [10]

9514 1404 393

Answer:

   B)  -3

Step-by-step explanation:

There are methods for finding only c. Cramer's rule is one of them. It involves finding two determinants and taking their ratio. Here, we choose a more <em>ad hoc</em> approach. It appears that the value of b can be found by combining the last two equations.

  (1/2)(2a +4b -2c) -(a -3b -c) = (1/2)(12) -(-4)

  5b = 10

  b = 2

Now, we can substitute this value into the first two equations. This gives ...

  5a +c = -8

  a - c = 2

Subtracting 5 times the second from the first gives ...

  (5a +c) -5(a -c) = (-8) -5(2)

  6c = -18 . . . . simplify

  c = -3 . . . . . . divide by 6

The value of c is -3.

What is the solution of the system? Use elimination. 7x + 5y = 19 −7x − 2y = −16
netineya [11]

Make the coefficient of y the same in both equations:

To do this, multiply equation one by 2, and equation two by 5 (this will make the coefficient 10 in both).

14x + 10y = 38
-35x - 10y = -80


Eliminate the y variable by adding the equations from each other

   (14x + 10y = 38)
+ (-35x - 10y = -80)
=  -21x +  0y  = -42

We now have -21x = -42. The y variable has been eliminated.


Solve for x

-21x = -42

Divide both sides by -21 to get x on its own.

x = 2


Substitute x into the equation to find y.

7*2+5y=19

14+5y=19

Subtract 14 from both sides.

5y=19-14

5y=5

Divide by 5 on both sides to get y on its own.

y=5/5

y=1


The answer is (2,1)

Answer:

<FSM=92

Step-by-step explanation:

5x+32=7x+8 (vertically opposite angles are equal)

  • 7x-5x=32-8
  • 2x=24
  • x=24/2
  • x=12

so <FSM =7x+8=7×12+8=92
