The equation of the line is:
Step-by-step explanation:
The equation of a line has the following format:
In which m is the slope(suppose we have two points, the slope is the change in y divided by the change in x).
b is the y-intercept(the value of x when y = 0).
In this question:
When , so
Passes through the points (0,1) and (1,2). So the slope is
The equation of the line is:
Answer:
Step-by-step explanation:
no.of pens=10
cp of i pen=x cp of 5 pens =5x
profit.A=25% of c.p= 0.25*5x=1.25x
profit= sp -cp
or, 1.25x=sp-5x
sp=6.25x
2nd condition
loss . amount= 0.833x
loss=cp -sp
or,0.833x=5x-sp
sp=4.17x
sp1+sp2=625
or,6.25x+4.17x=625
x=59.98 or 60
cost price of i pen is Rs 60
Answer:
600
Step-by-step explanation:
Let's consider this question using algebra.
Imagine the number of bricks in the original pile is .
We are told that of the bricks are used for a project, meaning that has been used, leaving us with as our remainder.
Then, we are told that of the remainder are used to leave us with 50 bricks. This means that of the remainder is left, and this is equal to 50 bricks. This means that the remainder's original amount is equal to 150, because we are told that of the remainder is equal to 50.
So, we know that the remainder is 150, and we also know that the remainder is . Let's now use these to form an equation.
Because we know that a quarter of the original amount of bricks is equal to 150, we can multiply both sides of the equation by 4 to get the original amount of bricks in the pile.
So, there were 600 bricks in the original pile.
