Write an algebraic expression with two terms to represent the total of balloons sold my all 3. in terms C last year three 6th grade students alia crystal and shamika were selling balloons at the school winter dance to collect 360$ for a class trip to a zoo

30/c

Step-by-step explanation:

Evaluate 7a+b/b+c, if a=2, b=6, and c=4.Find the solution of 3(y+7)is less than or equal to 39 if the replacement set is {2,4,6,8,10.12}. The equation 4+9=4+9 is an example of which property of equality?

answer is:

1.75 pounds

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
