7r=-7/2
divide both sides by 7 to get r by itself
(7r)/(7) = (-7/2)/(7)
if you don't quite see it, think of multiplying both sides by 1/7 instead (its the same thing as dividing by 7)
(7r)*(1/7)=(-7/2)*(1/7)
r=-1/2
Answer:
The answer is 5
Step-by-step explanation:
4 times 2=8 then 8 minus 3 = 5
Therefore 5
12 = 4*3 = 2*2*3
8 = 4*2 =2*2*2
greatest common factor = 2*2 =4
they can have 4 teams: consisting of 3 boys and 2 girls
2xy + 5x -12y -30
x(2y + 5) - 6( 2y + 5)
(2y+5) (x-6)
C. base = 48ft, height = 50ft
The reason this is the answer is because in order to create a similar figure, the dimensions must be similar. 24 x 2 = 48 and 25 x 2 = 50.
Hope this helps!
