Answer:

Ted is correct. Maggie made mistakes while trying to isolate x for both equations.

Step-by-step explanation:

For 3x-2=0, in order to move -2 to the left side, Maggie had to add 2 on both sides because -2+2=0. The same problem is seen for x+5=0. Maggie had to subtract 5 on both sides because +5-5=0

Plug in 10 for p and solve for h:

-10+60=h+10000

*Simplify the left side of the equation by adding the terms*

50=h+10000

*Subtract 10000 from both sides*

-9950=h

Hope this helps!!

A furniture store pays a wholesale price for a mattress. Then, the store marks up the retail price to 150% of the whole price. L

Answer:

The retail price of the mattress before discount is $2400.

Step-by-step explanation:

Given:

A furniture store pays a wholesale price for a mattress. Then, the store marks up the retail price to 150% of the whole price.

Later, they put the mattress on sale For 50% off though.

The customer just left the match is on sale and paid $1200.

Now, to get the retail price of the mattress before the discount.

Let the retail price of mattress before discount be $x.$

And the discount = 50%.

Price customer paid after discount = $1200.

Thus, according to question:

$x-50\%\ of\ x=1200.$

$x-\frac{50}{100} \times x=1200.$

$x-\frac{50x}{100}=1200.$

$x-\frac{x}{2}=1200.$

$\frac{2x-x}{2}=1200.$

$\frac{x}{2}=1200.$

Multiplying both sides by 2 we get:

$x=2400.$

Therefore, the retail price of the mattress before discount is $2400.

If ABCD (shown below) is a parallelogram, what is the measure of angle ABC?

yarga [219]

Answer:

Step-by-step explanation:

From the property of parallelogram the opposite angels are equal so < DAB = < DCB so < DAB will become 16x.

9x + 5 + 16x(<DAB) = 180 ....... because it is straight line.

25x + 5 = 180

25x = 180 - 5

25x = 175

$\frac{25x}{25} = \frac{175}{25}$

x = 7

now let's substitute in the angle < DCB( 16x):-16 × 7= 112
To get < ABC lets use the property of parallelogram which says tha adjacent angles are supplementary. which means <ABC + <DCB = 180

<ABC + 112 = 180

< ABC = 180 - 112

< ABC = 68
