Answer:
The ratio of red to blue would be 60: 6 which can be simplified to 10:1.
Answer:
18
Step-by-step explanation:
When dilating a segment by a scale factor, we multiply the original length by the scale factor to find the length.
2*9 = 18
The rule of scientifinc notation is that we can use number between 0 and 10, so here we can use 2.8. Lets do this
280 000 000 = 2.8 * 100 * 1 000 000
Now we can just multiply 2.8 by 10 to the power of number of 0 reapeted
So

- its the result
Answer:
33+87+x=180
x=69
x+y=180
by linear pair
69-180
=111
y =111

Answer:

Step-by-step explanation:
-3(x-4)=2x+4x+5
distribute -3 into (x-4)
-3x+12=2x+4x+5
combine like terms
-3x+12=6x+5
subtract 6x on both sides
-3x-6x+12=5
combine like terms again
-9x+12=5
subtract 12 on both sides
-9x=-7
divide both sides with -9

x=
