<h3>
What are decimal numbers?</h3>
- The decimal numeral system is the most widely used system for representing both integer and non-integer numbers.
- It is the Hindu-Arabic numeral system's extension to non-integer numbers.
- Decimal notation is the method of representing numbers in the decimal system.
- Decimal refers to the base-10 number system, which is probably the most widely used number system.
- There are ten single-digit numbers in the decimal number system: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.
- The number following 9 is 10.
- The number following 19 is 20, and so on.
Decimal numbers:
- Three hundred eight thousandths ⇒ 308/1000 ⇒ 0.308
- Sixty thousandths ⇒ 60/1000 ⇒ 0.060
Therefore, given numbers in the decimal numbers form are:

It will increase by 5/9 of a degree.
If you convert the given equation into slope intercept form, you will have:
c = (5/9)f + 160/9
In this form, it is easier to see the slope. The line would be increase by a rate of 5/9.
Answer:
They should add gallons of the store-bought lemonade.
Step-by-step explanation:
Given that,
Two friends make 2 gallons of lemonade containing 30% lemon juice.
The amount of lemon juice in 2 gallons of lemonade is
= 30% of 2 gallons
gallons
Let they added x gallons of store-bought lemonade that contains 20% lemon juice.
The amount of lemon juice in x gallons of lemonade is
= 20% of x gallons
gallons
Now the total amount of lemon juice in the mixture is
gallons
gallons
Total amount of lemonade is = (2+x) gallons.
The percentage of lemon juice in the lemonade is
According to the problem,
⇒ 60+20x= 23(2+x)
⇒60+20x= 46+23x
⇒23x-20x= 60-46
⇒3x=14
gallon
They should add gallons of the store-bought lemonade.

To round, look to the right of the number rounding up, if number is higher than 5, round up if its lower than 4, the number will remain the same.
The number of miles she drove the van for is 250 miles
<h3>Solving linear equations </h3>
From the question, we are to determine the number of miles Shelly drove the van
The given equation which shows the relationship between the number of days she rented the van, d, and the number of miles she drove the van, m is
20d + 0.7m = 235
Now, if she rented the van for 3 days, that is, d = 3
Putting the value of d = 3 into the equation to determine the value of m
We get
20(3) + 0.7m = 235
60 + 0.7m = 235
0.7m = 235 - 60
0.7m = 175
m = 175 / 0.7
m = 250
Hence, the number of miles she drove the van for is 250 miles
