First convert all volumes to the same unit. After converting 750 ml to 0.75 liters, sum this with the 487 liters already added to get 487.75 liters. Subtract this from the total capacity of 1458 liters to get 970.25 liters, which is the additional volume needed to fill the hot tub.
To determine how much more water needs to be put into the hot tub, you need to subtract the volume of the water that has already been added from the hot tub's total capacity.
First, you need to convert all the volumes to the same unit. Since the total capacity of the hot tub is given in liters, it would be best to convert the 750 ml to liters. As 1 liter is equal to 1000 ml, 750ml is equal to 0.75 liters. So, the total volume of the water that has been added to the hot tub now is 487 liters + 0.75 liters, which equals 487.75 liters.
Subtract this volume from the total hot tub capacity: 1458 liters - 487.75 liters equals 970.25 liters. So, 970.25 liters more water needs to be added to the hot tub to fill it to its total capacity.

We want to graph the ordered pairs for the given line and domain.
The graph can be seen at the end of the answer.
Here we have the line:
y = 2*x + 4
And the domain x= {-2, 1, 2}
To get the ordered pairs, we just need to evaluate the line in the given values of x, we get:
for x = -2
y = 2*-2 + 4 = 0
The ordered pair is (-2, 0)
for x = 1
y = 2*1 + 4 = 6
The ordered pair is (1, 6)
for x = 2
y = 2*2 + 4 = 8
The ordered pair is (2, 8)
Now we just graph these points, as you can see below.

what is the mode?
The mode is the number that repeats itself the most in a sequence. In this case, the mode will be £140 since it repeats itslef the most (2 times).

Answer:
Simplifying
2n + 4 + 5n = -3n + 2
Reorder the terms:
4 + 2n + 5n = -3n + 2
Combine like terms: 2n + 5n = 7n
4 + 7n = -3n + 2
Reorder the terms:
4 + 7n = 2 + -3n
Solving
4 + 7n = 2 + -3n
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '3n' to each side of the equation.
4 + 7n + 3n = 2 + -3n + 3n
Combine like terms: 7n + 3n = 10n
4 + 10n = 2 + -3n + 3n
Combine like terms: -3n + 3n = 0
4 + 10n = 2 + 0
4 + 10n = 2
Add '-4' to each side of the equation.
4 + -4 + 10n = 2 + -4
Combine like terms: 4 + -4 = 0
0 + 10n = 2 + -4
10n = 2 + -4
Combine like terms: 2 + -4 = -2
10n = -2
Divide each side by '10'.
n = -0.2
Simplifying
n = -0.2
