John’s father is 5 times older than John and John is twice as old as his sister Alice. In two years time, the sum of their ages

oksano4ka [1.4K]

Answer:

8 years

Step-by-step explanation:

Let age of father be f

age of John be j

age of Alice be a

John's father is 5 times as old as John. We can write:

f = 5j

John is twice as old as Alice. We can write:

j = 2a

a = j/2

SUM OF ALL OF THEIR AGES (after 2 years) will be 58. We can write:

f+2 + j+2 + a+2 = 58

This becomes:

f + j + a + 6 = 58

f + j + a = 52

Now, we replace third equation with the first two (in bold) and get:

$f + j + a = 52\\5j + j + \frac{1}{2}j=52\\6.5j=52\\j=8$

So John is 8 years old

I’m so bad at this ughhhhhhhhhhhhhhhhhhh

Alexus [3.1K]

Answer:

a)6

b)v^2-u^2/2a

Step-by-step explanation:

a)Given that,

u=12

a= -6

s=9

We know that,

v^2=u^2+2as

or, v^2=(12)^2+2×(-6)×9

or,v^2=144-108

or,v^2=36

or, v=√36

∴v=6

(Ans)

b)If ,v^2=u^2+2as

then, u^2+2as=v^2

or,2as=v^2-u^2

or, s=v^2-u^2/2a

∴s=v^2-u^2/2a

Hope ya find it helpful.. Thanks a lot...

The CP of 25 articles is equal to the SP of 30 articles . Find the profit and loss percentage .

Studentka2010 [4]

Answer:

Loss = 16.67%

Step-by-step explanation:

Assume cost price(CP) of 1 article = x

Therefore cost price of 25 articles = 25x

Given cost price of 25 article = selling price of 30 articles

Clearly, it is a loss.

Selling price(SP) of 30 articles = 25x

$So , \ selling \ price\ of\ one\ article = \frac{25x}{30}\\\\Therefore , Loss \% = \frac{CP - SP}{CP} \times 100\\$

$=\frac{x - \frac{25x}{30}}{x } \times 100\\\\=\frac{30x - 25x }{30x }\times 100\\\\=\frac{5}{30} \times 100\\\\=16.67 \%$
