Answer: -5

Step-by-step explanation:

im going to assume tomorrow means Two more.....

$2+4x=-18$

brilliant.

lets do opposite calculations to both sides. what is the opposite of 2? negative 2. so lets subtract 2 from both sides.

we get

$4x=-20$

ok so now we have 4 times x. what is the opposite of this? 4 DIVIDED BY x.

ok now lets do the same to the other side. what is negative 20 divided by 4?

A man bought certain number of litches

Arlecino [84]

Answer: The loss is 4%

Step-by-step explanation:

Lets call litches that are 20 pcs per Rs 100 - litches A

that are 30 pcs per Rs 100- litches B

So a man can buy 2 pcs A per Rs 10

and 3 pcs B per Rs 10

6x pcs A per Rs 30x

and 6x pcs B per Rs 20x

Now he gonna sell the 12x litches for y Rs

Lets find y from the proportion

12x cost y

25 cost 100

y/12=100/25

y=48 Rs

So the man bought 6x A + 6x B for 20x+30x=50 Rs

And then he sold them for 48 Rs

Obviously the man gonna loose the money.

Lets find the losses in %

(50-48)/50*100=200/50=4%

The loss is 4%
