Create an equation from the word problem. 'of' indicates multiplication, 'decreased' indicates subtraction, 'increased' indicates addition. Let's use 'x' for the number.
Now solve for 'x'. Subtract 3/10x to both sides:
Add 13 to both sides:
Divide 4/10 to both sides or multiply by its reciprocal, 10/4:
I got three numbers ...
798, 1726, & 2654
Answer:
-6
Step-by-step explanation:
to find slope by counting you just count rise over run
to get from (1,-4) to (0,2) you must go up 6 and back 1
6/-1 (negative cause you went back)

The length of BC = 72
Solution:
Given ΔABC and ΔDEF are similar triangles.
ΔABC ΔDEF
AB = 54, BC = n, EF = 12, DE = 9
Similar triangle theorem:
If two triangles are similar then the corresponding sides are proportional to each other.
Substitute the given values, we get
Do cross multiplication.
Divide both sides of the equation by 9.
⇒ BC = 72
Option B is the correct answer.
The length of BC = 72.
