Answer:

Given :

A man buys a few number of books at RS 72 each and a few number of pens at RS 25 each .

To Find :

If he buys 11 articles and pays RS 510 altogether,find the number of each article bought by him .

Solution:

Total no. of article = 11

Let x be the no. of books bought for RS 72 each

So, No. of pens bought for RS 25 each = 11-x

Cost of x books = 72x

Cost (11-x) pens = 25(11-x)

He buys 11 articles and pays RS 510 altogether

So,72x+25(11-x)=510

72x+275-25x=510

47x=510-275

x=5

So,No. of pens bought for RS 25 each = 11-x=11-5=6

Hence 6 pens and 5 books were bought by him.

Step-by-step explanation:

Write the slope-intercept form of the equation of the line through the given point with the given
gizmo_the_mogwai [7]

Step-by-step explanation:

18. y-(-2) = -6(x-2)

y+2 = -6x+12

y = -6x+12-2

y = -6x+10

19. y-(-4) = -½(x-4)

y+4 = -½x+2

y = -½x+2-4

y = -½x-2

1 - 3x = 3x + 1 solve for x
lakkis [162]

Answer: x = 0

Step-by-step explanation:

1 - 3x = 3x + 1

then add 3x on both sides

1 = 6x + 1

then subtract 1 on both sides

0 = 6x

then divide by 6 on both sides

0 = x

so x = 0

IGIVEEEEEEEEEEEEEEEEE BRAINLILSTTT
Temka [501]

Answer:

first box (x): 10

second box (y): 12

Step-by-step explanation:

HIJ is a translation of HIJ

translation just means you move the whole thing without any rotations dialations ect just moving it

from the blue shape it is asking what do you have to do to the x and y to get to the purple shape

you have to go +_x and take away _y

when you add a digit to x it moves to the right

when you add a digit to y it goes one up

because the HIJ are equaly spaced it dosnt matter which one we choose cause it will have the same answer

im going to use J

on the blue J you can see the x value is -8

the purple J's value is 5

to get from -5 to 5 you add 10

-5+5=0

0+5=5

5+5=10

therefore the first box (x) is 10

same thing for the y value im going to use J again

blue y value of J is 7

purple y value of J is -5

their distance is 12

7-7=0

0-5=-5

7+5=12

second box (y) is 12

i hope this helps
