the combined score for yakubu in geography, economics and science is 194. he scored twice as many marks in economics as in geogr
SVETLANKA909090 [29]

The scores of geography, economics and science are 38, 76, 80 respectively.

Let Yakubu scored x marks in geography.

Given that the score of him in economics is twice of the score of him in geography.

So, his score in economics = 2x

Again it is given that, the score in science is 4 more than the score in economics.

So the score in science = 2x+4

According to question the combined total score is 194. So the suitable equation is,

x+2x+2x+4 = 194

Solving the equation we get,

5x+4 = 194

5x = 194-4

5x = 190

x = 190/5

x = 38

So the score in geography = 38

the score in economics = 2x = 2*38 = 76

the score in science = 2x+4 = 2*38+4 = 76+4 = 80

Hence the scores of geography, economics and science are 38, 76, 80 respectively.

The​ U.S.-based motorcycle manufacturer says that it expects to build 139,000 motorcycles this​ year, up from 122,000 last year.
NemiM [27]

Solution:

we are given that

The​ U.S.-based motorcycle manufacturer says that it expects to build 139,000 motorcycles this​ year, up from 122,000 last year.

It mean the increased production is 139,000-122,000=17000

The percentage change in production can be found using the formula as below

Percenatge  \ increase=\frac{change}{Initial}*100\\&#10;\\&#10;\text{Substitute the values we get}\\&#10;\\&#10;Percenatge  \ increase=\frac{17000}{122,000}*100\\&#10;\\&#10;\&#10;Percenatge  \ increase=13.93\\

Hence the percentage increase is 13.93.
