3/10 due to there being 10 marbles (for white) for blue 7/10
Answer:
No
Step-by-step explanation:
1.2/3 =0.4
4/5 can be written as 0.8
So, 1.8/0.8 = 2.25.
However, 1.8/4/5 is the same as:
1.8/1 ÷ 4/5
Keep Change Flip
1.8/1 x 5/4 = 9/4
(1.8 x 5=9 & 1 x4 =4)
9/4 =2.25
Answer:
The first one is missing (d - 9) so it would be 5(d -9) or when you factor it out 5d - 45
In the second one (d + 7) is missing so it will be 8d(d + 7) so if you factor that out you will receive 8d^2 + 56
Step-by-step explanation:
3d^2 + 18d -21 =(3d -3)( d + 7)
3d^2 -30d +27 =(3d -3)(d - 9)
