The local library has a children’s section with picture books and chapter books. The ratio is 2:3. If there are a total of 500 books in the children’s section, then how many chapter books are in the section?
Answer:
300, I think.
Answer:
there are 300 chapter books in the children's section
Step-by-step explanation:
the way you'd solve these kinds of problems is to turn it into an equation.
the ratio of 2:3 with a total of 500
becomes
2x + 3x = 500
2x + 3x = 500
combine like terms
5x = 500
divide both sides of the equation by 5
5x/5 = 500/5
x = 100
now, substitute x in the original equation.
2x + 3x = 500
200 + 300 = 500
There are 300 chapter books

Answer:
18=2x+7, The internship pays $5.50 an hour.
Step-by-step explanation:
The box on the far left is the amount the student is paid at their job, which is $18 an hour in this case. Solve 18-7 to get 11, then divide 11 by 2 to get the pay for the internship. To check your work, plug 5.50 into the equation.
18=2(5.50)+7
18=11+7
18=18
Answer:
The equation would be:
18 = 2x + 7
The internship pays $5.5 an hour
Step-by-step explanation:
18 - 7 = 2x
(Since we moved the 7 to the other side, in order to combine like terms)
11 = 2x
(Divide both sides by 2)
5.5 = x
(x = 5.5)
x would be the pay the internship pays an hour.

Answer:
7-9 you need to plug numbers into the formula y= mx+b where you plug the plots in M and B.
Step-by-step explanation:
I don't have a graph to plot 1-3 on but all you need to do is plot them and answer if they are parallel, perpendicular, or neither. (The property extends to other related geometric objects. A line is said to be perpendicular to another line if the two lines intersect at a right angle.) (In math, parallel means two lines that never intersect — think of an equal sign.) And if they don't fit either then its NEITHER

What distribution of clothing should Nancy have for German males and females? Should she produce more small or large sizes, or should she have an even distribution of all sizes?
Answer: I sacrificed my answer for yours here u go love
Step-by-step explanation:
Nancy should produce more large sizes of the male clothing for German men since the data is skewed left, meaning there are more data values that lie on the right side, representing taller males. For women, she can have a roughly even distribution of sizes since the data set is symmetric.
Nancy should produce more large sizes of the male clothing for German men and for women, she can have a roughly even distribution of sizes since the data set is symmetric.
What is skewness in histogram?Skewness is the tendency for the values to be more frequent around the high or low ends of the x-axis.Skewness is the measure of the asymmetry of a histogram (frequency distribution). A histogram with normal distribution is symmetrical.Given is to find what distribution of clothing should Nancy have for German males and females.
The shape of the data for German male adult heights is skewed left, but the shape of the data for female adult heights is close to symmetric. So, the distribution of the data is not the same. Each data set has the same minimum height of 145 centimeters. However, the maximum male adult height is 220 centimeters and the maximum female height is 185 centimeters. So, the range of values is not the same. The data for male adult heights has an outlier, but the data for female adult heights doesn't have any outliers.Nancy should produce more large sizes of the male clothing for German men since the data is skewed left, meaning there are more data values that lie on the right side, representing taller males. For women, she can have a roughly even distribution of sizes since the data set is symmetric.
Therefore, Nancy should produce more large sizes of the male clothing for German men and for women, she can have a roughly even distribution of sizes since the data set is symmetric.

D. 13x - 27/9
Answer:
The answer is B.
Step-by-step explanation:
The simplified expression is 7x - 27/9
What is expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division. For example, x + y is an expression, where x and y are terms having an addition operator in between. In math, there are two types of expressions, numerical expressions - that contain only numbers; and algebraic expressions- that contain both numbers and variables.
An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division. The terms involved in an expression in math are:
Constant: A constant is a fixed numerical value.Variable: A variable is a symbol that doesn't have a fixed value.Term: A term can be a single constant, a single variable, or a combination of a variable and a constant combined with multiplication or division.Coefficient: A coefficient is a number that is multiplied by a variable in an expression.Given:
5(2x - 3) - 3(x + 4) / 9
=10x-15-3x-12/9

Answer:
x² - 100
Step-by-step explanation:
Use the FOIL method. The FOIL method is the way in which you multiply the terms:
FOIL stands for First, Outside, Inside, Last. Multiply:
First:
x * x = x²
Outside:
x * 10 = 10x
Inside:
-10 * x = -10x
Last:
-10 * 10 = -100
Combine like terms:
x² + 10x - 10x - 100
x² + (10x - 10x) - 100
x² - 100
x² - 100 is your answer.

If the fraction for cranberry juice is 3/12, what would be the missing number in the ratio?
Answer:
3
Step-by-step explanation:
Drink mix ratio:
Lemonade : Orange : Cranberry
6 : 3 : C
Fraction of Cranberry juice = [tex]\frac{3}{12}[/tex]
Sum of the ratio = 6 + 3 + C = 9 + C
Fraction of Cranberry;
[tex]\frac{C}{9 + C}[/tex] = [tex]\frac{3}{12}[/tex]
3(9 + C) = 12C
27 + 3C = 12C
27 = 12C - 3C
