Last year , there were 30 male members and 20 female members in a Chess Club . This year , the number of male members is decreas
LekaFEV [45]

The r% of a quantity x is computed by dividing x in 100 parts, and considering r of such parts. So, the r% of the male is

30\times\cfrac{r}{100} = 0.3 r

and similarly, the r% of female is

20\times\cfrac{r}{100} = 0.2 r

The number of males decreased by this quantity, so now it is

30 - 0.3r

and the number of female increased by this quantity, so now it is

20+0.2r

we know that these two new counts are the same number, so we can build and solve the equality

30 - 0.3r = 20+0.2r

Subtract 20 and add 0.3r from both sides:

10 = 0.5r

Divide both sides by 0.5 to solve for r:

r = 20

Let's check the answer

The 20% of 30 is 30 \times \frac{20}{100} = 6, while the 20% of 20 is 4. So, we are stating that 30-6 = 20+4 which is true because both expressions evaluate to 24.

Solve the equation<br> 0.2(d-6)=0.3d+5-3+0.1d for d
WINSTONCH [101]

Answer:

d= -16

Step-by-step explanation:

To answer this question you'll have to first simplify the equation to

0.2d+-1.2=0.3d+5-3+0.1d

then combining like terms you get

0.2d-1.2=(0.3d+0.1d)+(5+-3)

0.2d-1.2=0.4d+2

then subtract 0.4d from both sides leaving you with

-0.2d-1.2=2

then add 1.2 to both sides

-0.2d=3.2

after you divide both sides by -0.2

leaving you with the answer

D= -16
