Ashley draws a square that has a diagonal of
15 centimeters. what is the length of one side of the square? round your answer to the nearest tenth.

The length of one side of the square is approx 10.6 cm.

Step-by-step explanation:

Ashley draws a square that has a diagonal of  15 centimeters.

As it is a square, it will have 4 sides equal.

Now when a diagonal is drawn using 2 sides of the square, then it will form a right triangle with 2 sides as (suppose x) and hypotenuse as 15.

Solving this question using Pythagoras formula we get:

=>

=>

x = 10.60

Hence, the length of one side of the square is approx 10.6 cm.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
