Consider the equation 1/3x−2=x+2. Write a system of linear equations using each side of the equation. Then solve the original eq

kiruha [24]

System:

$y = \frac{1}{3}x - 2$
$y = x+2$

Solution: (-6,-4) for the graphed system( the point of intersection)
Note: when substituting -6 in for x in the original equation we see that it satisfies the equation. So -6 is the solution of the original equation.

Three small squares are drawn inside a larger square as shown. What is the length of the line marked with a question mark?

german

Answer:

19

Step-by-step explanation:

let the smallest square be A, medium square is B and the largest is C ;

as the length side of the main square is 28, we can find that,

A= 28-22 = 6

C= 28-15 = 13

So to find B,

A+B+C = 28

B = 28-A-C

B = 28-6-13 = 9

So the line with questioned mark is,

28-9 = 19
