Answer:
X <= 4
Step-by-step explanation:
-3x - 24<= -36
Make -3x the subject, by carrying -24 to the other side
Note: Moving -24 to the other side changes to + 24
-3x <= -36 + 24
-3x <= - 12
Minus cancels minus
3x <= 12
Divide both sides by 3,to get the value of x
3x/3 <= 12/3
x <= 12/3
x <= 4
Therefore, x equals to 4
The actual distance would be 28mi
Answer:
x=13, A=169
P=4s, so you substitute P with 52 and you're left with 52=4a. You divide 4 to both sides of the equation and a(or x) equals 13.
A=s^2, so since your side(x) equals 13 you calculate 13^2 or 13×13, and A=169.
140>120
70% of 200>3/4*160
Answer:
120,960 ways
Step-by-step explanation:
Assuming that each piece is unique, then the order of each piece matters.
There are 9 pieces in total, there are 3 options for the first piece (3 piano pieces), and the remaining 8 pieces can be permuted. The number of possible arrangements is:
The program can be arranged in 120,960 ways.
