The sum of 10 times a number in 15 is added to 11 times the same number

Now, let x equal the number:

10 times the number is 10x.

Sum of 10 times the number and 15, means sum of 10 times the number plus 15, which is 10x + 15.

Eleven times the same number, means 11 times x, which is 11x.

Sum of 10 times a number and fifteen is added to eleven times the same number is therefore: 10x + 15 + 11x = 21x + 15

Step-by-step explanation:

the answer is 24

step-by-step explanation:

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
