Sally gave her brother $3.95 in quarters and dimes. if the number of quarters is 6 more than the number of dimes, how many quarters did sally give her brother? sally gave her brother quarters. nextreset

13 quarters.

Step-by-step explanation:

Let d represent number of dimes and q represent number of quarters.

We have been given that the number of quarters is 6 more than the number of dimes. We can represent this information in an equation as:

We know that value of one dime is $0.10, so value of d dimes would be .

We know that value of one quarter is $0.25, so value of q quarters would be .

We have been given that Sally gave her brother $3.95 in quarters and dimes. We can represent this information in an equation as:

Now, we have a system of linear equation and we will solve our system by substitution method.

From equation (1), we will get:

Upon substituting this value in equation (2), we will get:

Therefore, Sally gave her brother 13 quarters.

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
