Hello there! the answer would be x = 3/4.

You are given the two equations: 4x - 2y = 8 and y = 1/2x + 2. You are asked to solve via substitution. To do this, substitute the value of y in the second given equation into the first given equation, and solve using PEMDAS.

4x - 2(1/2x + 2) = 8 - Start by distributing 2 into (1/2x + 2).

4x - 1x + 4 = 8 - Combine like terms.

3x + 4 = 8 - Subtract 4 from both sides.

3x = 4 - divide both sides by 3.

x = 3/4. This is your final answer.

I hope this was helpful, have a great day! :)

Lady bird [3.3K]

Answer:

He should sell each pen of Rs.0.8625 so as to make a gain of 15%

Step-by-step explanation:

Cost price of 100 pens = Rs.75

Cost price of 1 pen= $\frac{75}{100}$ = 0.75

Gain%= 15%

Gain= $15%$ $X 0.75$ $= 0.1125$

SP = CP+Gain = 0.75+0.1125=0.8625

When calculating probability you need to remember that probability is:
something that you are observing divided by total number of participants.
The number you get is relative value(has value between 0 and 1) and if you want to get it in percentage (more clearly) just multiply it with 100.

In this case we are observing blood type B persons. Number of them is 165.
Total number of persons is 1500. Therefore our calculation looks like this:

165/1500 = 0.11 or the probability is 0.11*100=11%
