We are given that 14 inch represent 38 foot.
To know the model length that represents 1 foot, all we have to do is cross multiplication as follows:
14 inch ..............> 38 foot
?? inch .............> 1 foot
length on model = (1*14) / 38
length on model = 7/19 inch = 0.36842 inch
Answer:
(-3, -2)
Step-by-step explanation:
Look at the second equation, we can easily rearrange it to make x the subject.
x - 4y = 5
x = 4y + 5
Now lets put that into the second equation
2x - 2y = -2
2(4y + 5) - 2y = -2
6y + 10 = -2
6y = -12
y = -2
Now lets find x!
x = 4y + 5
x = 4(-2) + 5
x = -3
Now lets format the answer like the question says (ordered pair)
(-3, -2)
Recap: We used substitution and made an equation to work out one of the variables first, then found the second variable using the first.
Answer:
A minimum of 16 rows are needed
Step-by-step explanation:
Here, we want to calculate the number of rows minimum that could seat 382 people in rows of 24 seats.
Mathematically, what we need to do here is to make a division.
We shall divide the number of people by the number of seats in a row so that we can get the number of rows needed.
Mathematically, that would be; 382/24 = 15 22/24
We are looking at a minimum number.
So we can see that 15 rows will be filled, with an extra 22 seats in the next row leaving only 2 seats in the next row unoccupied.
So we can see that the minimum number of rows required is 16 rows
