One number is four more than a second number. two times the first number is 10 more than four times the second number

Write an equation for each statement:

:

"one number is four more than a second number."

x = y + 4

:

" two times the first number is four more than four times the second number"

2x = 4y + 4

;

From the 1st equation, substitute (y+4) for x in the above equation

2(y + 4) = 4y + 4

2y + 8 = 4y + 4

8 - 4 = 4y - 2y

4 = 2y

y = 4%2F2

y = 2, the second number

and

x = 2 + 4

x = 6, a number

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
