Step-by-step explanation:
1. Let the number be a
2 + 3a = (-10)
3a = -10 - 2
3a = -12
a = -12/3 = -4.
2. Let the number be x
3x + 20 = 11
3a = 11 - 20
3a = -9
a = -9/3 = -3
3. Let the number be n
7x/10 = 5.6
x = 5.6 × 10/7
x = 56/7
x = 8

What is the inverse of the function f(x) = 2x – 10?
Answer:
The inverse f-1(x) = ( x + 10)/2.
Step-by-step explanation:
f(x) = 2x - 10
Find x in terms of f(x):
2x = f(x) + 10
x = (f(x) + 10))/ 2
Replace x by the inverse f-1(x) and f(x) by x:
f-1(x) = (x + 10)/2.

Which Statement is not true based on the figures below?
A statement that is not true based on the figures would be A; CD = JK
WE are given the figure of two similar pentagon figure that are;
ABCDE and JKLMN
Similar figure are zoomed in or zoomed-out (or just no zoom) version of each other. For two similar figures, the pair-by-pair similar angles of those two similar figures are called corresponding angles tthat are of same measurement.
Thus, we can see that the sides are similar to each other.
AB = JK
CB = LK
CD = LM
DE = MN
AE = JN
Since CD = JK is not valid
Therefore, we can conclude that the first statement is incorrect.
Hence, the answer is A.

Answer:
[tex] \frac{11}{7} [/tex]
Step-by-step explanation:
[tex]2 \frac{3}{4} \div 1\frac{4}{7} [/tex]
[tex] = 2 \frac{3}{4} \times \frac{4}{7} [/tex]
[tex] = \frac{11}{4} \times \frac{4}{7} [/tex]
[tex] = 11 \times \frac{1}{7} [/tex]
[tex] = \frac{11}{1} \times \frac{1}{7} [/tex]
[tex] = \frac{11 \times 7}{1 \times 7} [/tex]

Find the equivalent equation that results from adding 5 to both sides first and then multiplying
both sides by 2. Show each step. You do not have to solve the equation at the end.
Answer:
5d = 30
Step-by-step explanation:
1. first you need to add 5 to both sides
d-4+5 = 2+5
2. then you need to combine like terms
d+1 = 7
3. after that you have to multiply both sides by 5
5(d+1) = 7(5)
4. simplify
5d + 5 = 35
-5 -5
5d = 30

How is proportional reasoning used to interpret distances on maps?
Answer:
It shows how a dimension in a scale drawing is related to the actual object. A map is a scale drawing. The measurements on a map are in proportion to the actual distances. If 1 inch on a map equals an actual distance of 2 miles, the scale is 1 inch = 2 miles

Suppose the function E(c) represents the earnings of a volleyball team from selling c cupcakes. They are selling each cupcake for $2. They only bought enough supplies to make 100 cupcakes. Describe an appropriate domain and range of this function using interval notation.
Using domain and range concepts, it is found that:
An appropriate domain for the function is: [tex]c \in [0,100][/tex]An appropriate range for the function is [tex]E \in [0,200][/tex].------------------------------
The domain of a function are the values that the input can assume.The range of a function are the values that the output can assume.------------------------------
The function E(c) represents the earnings of selling c cupcakes.The input is the number of cupcakes sold c.The output is the earnings E.------------------------------
They have enough supplies to make 100 cupcakes, thus, at most 100 cupcakes can be sold, meaning that an appropriate domain for the function is: [tex]c \in [0,100][/tex]If no cupcakes are sold, the earnings will be of $0. If all 100 cupcakes are sold, the earnings will be of $200, as each is sold for $2, meaning that an appropriate range for the function is [tex]E \in [0,200][/tex].A similar problem is given at https://brainly.com/question/2145599

In 2015, the city of Miami had a population of 441,000 people and an area of 36 square miles. What was the population density of Miami, in people per square mile, in 2015? 10,750 12,250 14,250 16,750
Answer:
12,250
by dividing the 441000 by 36, I got the answer.
The population density of Miami, in people per square mile, in 2015 was 12,250
The given parameters are:
Population = 441,000 peopleArea = 36 square milesThe population density of a place is the ratio of the population to the unit square area.
So, we have:
[tex]Density=\frac{Population}{Area}[/tex]
Substitute known values
[tex]Density=\frac{441000}{36}[/tex]
[tex]Density=12250[/tex]
Hence, the population density of Miami, in people per square mile, in 2015 was 12,250
