Answer:
2x + 4y = $50
x = $5, and y = $10
Step-by-step explanation:
let the price of student's ticket be represented by $x, and that of adult by $y. So that:
2x + 4y = $50 ................ 1
But, given that adult tickets are $5 more that student tickets.
i.e y = x + $5 ................. 2
Substitute equation 2 into 1, to have;
2x + 4(x + $5) = $50
2x + 4x + $20 = $50
6x = $30
x = $5
From equation 2,
y = 5 + 5
= $10
Therefore, the price of student tickets is $5 and adult tickets is $10.
well since the formula is pi times radius squared that means it's 4 pi times 4 pi since the radius is squared so it's 16 pi
We know that the variation is proportianal, that is we can relate the quantities as:
where y is the mass of the body and x is the mass of water. From the values given we have that:
hence the constant of proportionality is 3/2. Now, if the mass of the water is 75, then the mass of the body is:
Therefore, the mass of the body is 112.5 kilograms
Answer:
it will take 20 hours for 18 bakers to complete the same order
Step-by-step explanation:
15 bakers take 24 hours
18 bakers take x hours
15 * 24 = 360 "baking hours"
18 * x = 18x " baking hours"
360 baking hours = 18x baking hours
360 = 18x
18 18
20 = x
x = 20 hours
