Answer:
3r − 9 = –6r
-9 = -6r-3r (you change the signs when bringing +3r to the other side)
-9 = -9r
r = -9/-9
r = 1
Answer:
B) 180 ft. squared
Step-by-step explanation:
Multiply all sides of the figure by 3 because of the scale factor
6 times 12 = 72 (for the rectangular part)
6 times 6/2 = 18 (for the triangular part)
We know that the base and height of the triangle are congruent because of the tic marks
18 + 72 = 90
Multiply by 2 since that is only half of the side of the house
90 times 2 = 180

A fraction that means the same as 2/3 is 4/6.
To find this, you can simply multiple both the numerator and denominator (top and bottom) by any number as long as it's the same number for both top and bottom.
In this case, we used 2 as the number, and multipled it to the top and bottom of 2/3, to get 4/6.
I hope this helps!
