The sum of two numbers is 5000. if 20% of one number is equal to 30% of other no. find the number

Alex Ar [27]

W +Y =5000

20/100 x W= 30/100 X Y

W/5=3Y/10

10W=15Y

W=15Y/10=3Y/2

3Y/2+Y=5000

3Y+2Y=10,000

5Y=10,000

Y=2000

AND HENCE W=3 x2000/2=3000

What is the slope of the line that passes through the points (-2, 7) and (2, -5) ?

masha68 [24]

Answer:

Step-by-step explanation:

Since the slope of a line is its gradient, we use the formula for finding gradient.

Gradient

$= \frac{change \: in \: y}{change \: in \: x } \\ \ = \frac{7 - - 5}{ - 2 - 2 } \\ = 12$

hope it helps.
