Answer:
54 teachers
Step-by-step explanation:
Step one:
given data
The ratio of teachers to students on a field trip to New York City is 2 to 9.
That is the ratio is 2:9
We are told that there are 243 students
Required
We want to find the number of teachers
Step two:
Applying the part to part method we have
let the number of teachers be x
2/9= x/243
cross multiply we have
9x= 243*2
9x= 486
divide both sides by 9
x= 54
Hence there are 54 teachers
Answer:
YES
Step-by-step explanation:
First, let's find the total number of seats int he airplane.
14 + 64 + 4 * 108 = 510
The airplane has a total or 510 seats.
Half of the number of seats is 510/2 = 255.
Now let's calculate the number of seats being used and compare with 255.
5/7 * 14 + 5/16 * 64 + 5/9 * 4 * 108 =
= 2 * 5 + 4 * 5 + 12 * 4 * 5
= 10 + 20 + 240
= 270
270 seats are being used.
270 is greater than 255, so more than half of the seats are being used.
Answer: YES
Hello!
You can solve this algebraically
7w < -42
Divide both sides by 7
w < -6
The answer is any number less than -6 or w < -6
Hope this helps!
