The scale factor is 5
-2*5 is=-10
6*5=30
0,-8 are the coordinates of the vertex.
Answer:
5) 1.5 : 7
Step-by-step explanation:
I think for 4) you need only one ratio, for example
The ratio of lemon to sugar is
1 : 1,5
This is the same lik 2:3, or any other you wrote. So it is enough to write just one ratio.
5) also one ratio is enough, becuse all other are the same.
The ratio of cups od sugar to cups of water is 1.5 : 7.
Answer:
x = 2.5
Step-by-step explanation:
In order to solve for x, we need to write an equation. This question gives us the angles of a triangle, so we can use this to write our equation. All angles of a triangle will always add to 180 degrees, therefore:
(12x+6) + 104 + 40 = 180
Now we can just take out the brackets, combine like terms and isolate and solve for x:
12x + 6 + 104 + 40 = 180
12x + 150 = 180
12x + 150 - 150 = 180 - 150
12x = 30
12x/12 = 30/12
x = 2.5
Hope this helped!
