Answer:
C. 16
Step-by-step explanation:
Brother - b years now.
Sister - s years now.
A brother is 12 years older than his sister.
b - s = 12
(b - 4) - brother 4 years ago.
Four years ago, the brother was 3 times as old as the sister is now.
b - 4 = 3s
b - s = 12 ----> s = b - 12
b - 4 = 3s
b - 4 = 3(b - 12)
b - 4 = 3b - 36
36 - 4 = 3b - b
32 = 2b
b = 16
Answer:
a. 2/5; reduction
Step-by-step explanation:
It appears that C is the center of dilation, so C' and C are coincident. The scale factor is ...
P'C'/PC = 4/10 = 2/5 . . . scale factor
The scale factor is less than 1, so the dilation is a <em>reduction</em> in size.
Answer
131ft^2
Step-by-step explanation:
I find area by basically taking the figure and making it into two figures and solving the area for the two then adding them up.
Where are the answer choices?
but the answer either way has to be:
v = d/t . v is velocity, d is for distance, and t is for time
Answer: look at the bottom
Step-by-step explanation:
Difference of two negative numbers may or may not be negative. It depends on the numbers taken as well as on the sequence in which they are taken. Then, a-b=b-a=0, (which is neither negative nor positive..!!!) So difference of two negative numbers may be positive, negative or even zero.
