The answer is: If x is the number of gallons that the tank holds, do you agree that 28 * x is the number of miles the car could travel on a full tank of gas?
Answer:
the answer is ÷
Step-by-step explanation:
Answer:
A) $15t - $700 ≥ $1000
B) At least 114 tickets
C) As the attached graph
Step-by-step explanation:
The 7th grade class is putting on a variety show to raise money.
It cost $700 to rent the banquet hall that they are going to use.
If they charge $15 for each ticket,
We are to find how many tickets they need to sell in order to raise at least $1000.
Let the number of tickets they need to sell be t.
The inequality that represents this situation is;
$15t - $700 ≥ $1000
The least number of tickets they can sell is;
$15t ≥ $1000 + $700
$15t ≥ $1700
t ≥ 113.3333 (rounded to four decimal values)
But since we can have 0.3 tickets the class will have to sell at least 114 tickets
The graphed situation is as attached. We need the shaded region.
Answer:
Jan bought 4 steaks and 6 watermelons.
Step-by-step explanation:
let the number of steaks sold be x
let the number of watermelons sold be y
the following information were given:
x + y = 10 - - - - (1) ( bought a total of 10 steaks and watermelons.)
5(x) + 4.5(y) = 47 - - - - - (2) (Jan spent $47)
let us solve for x and y as follows:
x + y = 10 - - - - (1)
x = 10 - y - - - - (3)
putting the value of x in equation (3) to replace x in equation (2)
5(x) + 4.5(y) = 47 - - - - - (2)
5(10 - y) + 4.5(y) = 47
50 - 5y + 4.5y = 47
50 - 0.5y = 47
50 - 47 = 0.5y
3 = 0.5y
∴ y = 3 ÷ 0.5 = 6
since we know the value of y, the value of x is solved using equation 3 as follows:
x = 10 - y - - - - - (3)
x = 10 - 6 = 4
Therefore, Jan bought 4 steaks and 6 watermelons.
This is a problem for 2 equations and 2 unknown.
so let x be the number of adults in the breakfast
y be the number of children present in the breakfast
so the total people attended is 500, in equation form
x + y = 500
and the total sales made by disney is $ 7355, in equation
17.95x + 12.95y = 7355
so we can solve the equation simultaneously so solve for the values of x and y
so the number of adults at the breakfast x = 176 adults and y = 324 children
