Her check register will have a surplus of 64 dollars compared to her actual balance.
example
100 +32 = 132 (incorrect)
100 -32 = 68 (correct)
132 -68 = 64 surplus
In order to find the slope of a line, u must use the slope formula. Which is (y2-y1/x2-x1). For example if you had a set of coordinates that are (6,4) and (2,8) you would first sub the 8 from4 which gives you 4. The u do the same with 2 and 6 which gives u 4. After that you divide 4 by 4. and your answer is 1
Answer:
16% of 50 = 8
Step-by-step explanation:
50x0.16=8
We know 10 percent of 50 is 5, so 20 percent of 50 is 10.
8 comes between 5 and 10, so it’s reasonable.

Answer:
CD=14
DE=21
Step-by-step explanation:
ΔCDE is similar to ΔFNE (∠E≅∠E, ∠NFE≅∠DCE) by AA similarity
Using Thales' Intercept Theorem Corollary, you know that:
EN/ED=EF/EC=NF/CD=12/20
Let DN be 8x and NE be 12x
Let NF be 12y and CD be 20y
Then you have a system of equations:
20x+20y+20=55
8x=12y
By solving them, you get y=0.7 and x=1.05⇒
DE=21 and CD=14
