Answer:
10
Step-by-step explanation:
Your scale factor is 3/2, because when you compare AC and DF, the ration is 18/12, or 3/2. We can set up a proportion:
3/2=15/x
We cross multiplu
3x=30
x=10
So, the length of DE is 10 units.
Hope this helps!
Answer:
y = 3
Step-by-step explanation:
The equation of a horizontal line parallel to the x- axis is
y = c
where c is the value of the y- coordinates the line passes through.
here the line passes through (0, 3) with y- coordinate 3
y = 3 ← is the equation of the horizontal line
A decimal in the wrong place can change the value of a number completely for example
0.5 can be converted to 50 cents or 1/2 but if you change the decimal 0.05 converts to 5% or 1/20.
