If R is the midpoint of QS, RS=2X-4, ST=4X-1, and RT=8X-43, find QS

1 answer:

3 0

RT = RS + ST
8x - 43 = 2x - 4 + 4x - 1
8x - 43 = 6x - 5
8x - 6x = -5 + 43
2x = 38
x = 38/2
x = 19

QS = 2RS = 2(2x-4) = 2(2*19-4) = 2*34 = 68

If the foreign exchange rate between the japanese yen and the euro is 190:1, how many yen will equal 10 euros?

alexgriva [62]

Alright, lets get started.

The foreign exchange rate between the japanese yen and the euro is 190:1 given.

It means 1 euro = 190 yen

We are asked to find how many yen will be equal to 10 euros.

Means we need to multiply given euros with 190 because 1 euro = 190 yen

Hence 10 euros $= 190 * 10$ yen

10 euros = 1900 yen : Answer

Hope it will help :)

14 T 1,000 lb. + 2 T 1,000

Olegator [25]

The answer will be 17 tons.

Step-by-step explanation:

Since we have given that

14 T 1,000 lb. + 2 T 1,000 lb.

As we know that

$1\ ton=2000\ lbs\\\\14\ tons=2000\times 14\ lbs\\\\14\ tons=28000\ lbs$

So, 14 T 1,000 lb. is given by

$28000\ lbs+1000\ lbs\\\\=29000\ lbs$

Similarly,

$1\ ton=2000\ lbs\\\\2\Tons=2\times 2000\ lbs\\\\2\ tons=4000\ lbs$

so,

2T 1,000 lb. is given by

$4000+1000\\\\=5000\ lbs$

So, 14 T 1,000 lb. + 2 T 1,000 lbs is given by

$29000+5000\\\\=34000\ lbs\\\\=\frac{34000}{2000}\\\\=17\ tons$

Hence, the answer will be 17 tons.
