200 reduced by 2 times my age equals 16

Mathematics
1 answer:
Komok [63]3 years ago
8 0
Ok, so since it doesn't give a value for "my age", we'll call it x.  So the sentence translates into an equation...

200 reduced means... 200 -
by 2 times my age means... 2x
equals 16 means... = 16

200 - 2x = 16

Now let's solve for x to find "my age"

First subtract 200 from each side to begin to isolate x

-2x = -184

Divide each side by -2 to isolate x

x = -184/-2
x = 92

I'm 92 years old!

8. A furniture shop sells sofas for $880. If the shop wanted to offer the lower price of $640, what rate of markdown would it ha
geniusboy [140]

Answer:

The rate of markdown it would have to offer is 27.3%.

Step-by-step explanation:

The original price of sofa was, OP = $880.

The new price of sofa is, NP = $640

The change in price is:

Change=OP-NP\\=880-640\\=240

The rate of markdown offered by the shopkeeper is:

Rate\ of\ markdown=\frac{Change\ in\ Price}{Orignal\ Price}\times100 \\=\frac{240}{880}\times100\\ =0.27273\times100\\\approx27.3\%

Thus, the rate of markdown offered by the shopkeeper is 27.3%.

URGENT!!!!<br> The sum of two numbers is 44 and the difference is 4 . What are the numbers?
gladu [14]

Answer:

The 2 numbers are 24 and 20

Step-by-step explanation:

x+y = 44

x-y =4

Use elimination to solve this system

x+y = 44

x-y =4

-------------

2x = 48

Divide by 2

2x/2 = 48/2

x = 24

Now we need to find y

x+y =44

24+y =44

Subtract 24 from each side

24-24+y = 44-24

y =20
