Answer:
X = 9.5 + m
Step-by-step explanation:
m = money spent
x = money you had at the beginning
x = 9.5 + m
Substitute m in for 3.4
X = 9.5 + 3.4
Solve for x
X = 12.9
You started with $12.90
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!
