Answer:the total amount of water used by the two households on that Saturday is 360 gallons
Step-by-step explanation:
Let x represent the total amount of water used by the two households on that Saturday. On that Saturday, the ratio of the amount of water used by household A to the amount of water use by household B was 13 : 5. The total ratio is 13 + 5 = 18
The amount of water used by household A would be
13/18 × total amount of water.
The amount of water used by household B would be
5/18 × total amount of water.
Since household A used 260 gallons of water for that day, it means that
13/18 × x = 260
13x = 260×18 = 4680
x = 4680/13 = 360

The improper fraction of is ⇒ 10/3.
The given mixed fraction is
We know that
Every fraction is made up of two parts: the numerator and the denominator. Proper fractions and improper fractions are the two primary forms of fractions in mathematics depending on the numerator and denominator values.
An improper fraction is a type of fraction where the numerator is greater than or equal to the denominator
In order to convert it improper fraction proceed as follow
= (3x3 + 1)/3
= (9+1)/3
= 10/3
Thus improper fraction is 10/3

Answer:
the completed factor is (2x + 2)(x + 3).
Step-by-step explanation:
To complete the given factor, we need to find two binomials that multiply together to give us the expression 2x^2 + 8x + 6.
First, let's look at the coefficient of x^2, which is 2. The only way to factor 2x^2 is as 2x * x.
Next, let's look at the constant term, which is 6. We need to find two numbers that multiply to give us 6 and also add up to the coefficient of x, which is 8. The numbers that satisfy this condition are 2 and 3.
Therefore, the factors of 2x^2 + 8x + 6 are:
(2x + 2)(x + 3)
You can verify this by multiplying the two binomials together using the distributive property.
So, the completed factor is (2x + 2)(x + 3).
15 is 2 1/2 of a number 6.
We need to find that 15 is 2 1/2 of what number.
In math, 'of' is also considered one of the arithmeticoperations which means multiplication within the brackets.
Let the unknown number be y.
Now, 2 1/2 of y=15
⇒5/2 ×y=15
⇒y=6
Therefore, 15 is 2 1/2 of 6.

▪ Answer:
n = 6
▪ Step-by-step explanation:
n × 2 1/2 = 15
n × 5/2 = 15
n × 5 = 30
n = 30 ÷ 5
n = 6
The average rate of change will be negative 7 / 3.
Let the thing that is changing be y and the thing with which the rate is being compared is x, then we have the average rate of change of y as x changes as:
Average rate = (y₂ - y₁) / (x₂ - x₁)
The exponential function is given below.
f(x) = (0.5)ˣ - 6
Then the average rate of change will be
Average rate = [f(0) - f(-3)] / [0 - (-3)]
Average rate = [(0.5⁰ - 6) - (0.5⁻³ - 6)] / 3
Average rate = [1 - 6 - 8 + 6] / 3
Average rate = - 7 / 3
