Answer:
h=A*2b
Step-by-step explanation:
A=1/2bh
1/2bh=A
1/2bh÷1/2bh=A÷1/2bh (the 1/2b will cancel with the 1/2b on the left leaving h)
h=A*2b
Answer:
649 trains
Step-by-step explanation:
If there are 30 seats per carriage, and there is 18 carriages per train.
You multiple 30 and 18 to get how many seats there are in a train.
30*18 is 540 seats.
To figure out how many trains would be needed to seat 350,000 passenger, you have to divide 350,000 with 540 to get how many trains would be needed.
350,000/540 is 648.1
Since the answer is 648.1 and you can't chop a train into 10 pieces, you would need 649 trains to seat 350, 000 passengers.
Answer:I THINK 180
Step-by-step explanation: HOPE THIS HELPS
If you get an answer in the form of a=a, that means there are infinite solutions. So the answer would be infinite solutions.
Also, if it’s in the form of a=b (where a and b are not the same number), the answer is no solution or zero solutions.
The <span>sum of a number and 5, less than 10, is 3 can be expressed as:
x + 5 - 10 = 3
where x is unknown number.
x + 5 = 3 + 10
x + 5 = 13
x = 13 - 5
x = 8</span>
