Answer:
1.84
Step-by-step explanation:
So first we can do 5/7 which equals 0.714286
add 2 to that and get: 2.714286
So 5 / 2.714286 = 1.8421
Answer:
2 to the 3rd power,
2*2*2
4 to the 3rd power,
4*4*4
Step-by-step explanation:
The "3rd power" means how many times the number given to it would be multiplied. Aka, 2 to the 4th power would mean 2 times 2 times 2 times 2, (2 four times).
Answer:

Step-by-step explanation:
subtract 1 from both sides
-6x<-17-1
simplify
-6x<-18
divide by 6 on both sides
x>3
20,000,000+400,000+80,000+4000+100+60+3
Answer:
9 hr * 60 min/hr = 540 min. 540 min * 60 sec/min = 32,400 sec. Use the method described by panic mode: round the number down until there is only one non-zero digit left. Here, 32,400 rounds down to 30,000. Now count the number of zeroes; the result is the order of magnitude: 4. (You see this in scientific notation also: 30,000 = 3 × 10^4.)
