Answer:
9 ≤ p
Step-by-step explanation:
-18 ≤ -3p
-18/-3 ≤ p
9 ≤ p
It’s in scientific, currently. So you want to put it back the way you’d write it normally. Move the decimal two places to the right (bc x 10^2) to get 338.55
2a + 3b = 6
5a + 2b = 4
We multiply the first equation by 5 and the second by 2 and and subtract the second from the first:
10a + 15b = 30
-10a -4b = -8
11b = 22
b = 2
2a + 3(2) = 6
2a = 0
a = 0
Checking,
5(0) + 2(2) = 4
4 = 4, true
Answer:
8:15 pm
Step-by-step explanation:
A concert starts by 7:00pm
They perform for 30 minutes
There is a 15 minutes break
The band performs for another 30 minutes
Hence the concert will end by 8:15 pm
After it is fully simplified, it will be 5x+1-3y
