Answer:
y= -3
Step-by-step explanation:
<u>Multiply all terms by the same value to eliminate fraction denominators:</u>
2/y +3 = 3/3y + 9
(3y+9) (y+3) (2/y+3) = (3y +9) (3/3y+9)
<u>Simplify:</u>
6
+
1
8
=
3
+
9
<u>Subtract 18 from both sides of the equation:</u>
6y +18 =3y +9
6y+18 -18 =3y +9 -18
<u>Simplify Again: </u>
6y +3y-9
<u>Subtract 3y from both sides of the equation:</u>
6y =3y -9
6y-3y = 3y -9 -3y
<u>Answer:</u>
y= -3
The numbers are 6 and 2. To figure this out, just find all the number that add up to 8, and see which set are 4 numbers apart.
Answer:
70 m^2
Step-by-step explanation:
The key shows that each square side on the grid measures 2 m. The base of the triangle measures 7 grid square sides, so it measures 14 m. The height of the triangle measures 5 grid square sides, so it measures 10 m.
area of triangle = bh/2
area = (14 m)(10 m)/2
area = 140 m^2/2
area = 70 m^2
