What is the solution for the equation? 3x + 15 -7x = 27
A. x = -3
B. x = 1.2
C. x = 3
D. x= -10.5
Answer:
A. x = -3
Step-by-step explanation:
add the "x"s together
-4x + 15 = 27
subtract 15 from both sides
-4x = 12
divide both sides by -4
x = -3
A. x = -3 is the answer :)

Select all the expressions that have a value of 40 when x = 10.8.
4,320 ÷ x
Answer: Option C.
Step-by-step explanation:
x = 10.8
A. = 4,320 ÷ x
= 4,320/10.8
= 400
Option A is incorrect.
B. = 288/x + 16
= 288/10.8 + 16
= 42.7
Option B is incorrect
C. = (x² ÷ 18) + 33.52
= (10.8² ÷ 18) + 33.52
= 40
Option C is correct
D. = (1,752 ÷ x) – 162/29
= (1,752 ÷ 10.8) – 162/29
= 156.6
Option D is incorrect
E. = x/12 + 36
= 10.8/12 + 36
= 36.9
Option E is incorrect
Answer:
x = 10.8
432 ÷ x = 40
(216 ÷ x) + 20 = 40
(108 ÷ x) + 30 = 40
(54 ÷ x) + 35 = 40

Write an expression for the length of the third side of an isocoles triangle
Answer:
[tex]y = 180 - 2x[/tex]
Step-by-step explanation:
Required
Triangle: Isosceles
Required
An expression for the third side
Let the equal sides be x and the third side be y
From triangle sum theorem, we have the following expression:
[tex]x + x + y = 180[/tex]
[tex]2x + y = 180[/tex]
Subtract 2x from both sides
[tex]-2x +2x + y = 180 - 2x[/tex]
[tex]y = 180 - 2x[/tex]
Hence, the third side of an isosceles triangle is: [tex]y = 180 - 2x[/tex]

-8x + 7y = -2 ( infinitely many solutions )
8x - 7y = 2
8x - 7y = 2
-8x + 7y = 2 ( zero solutions )
Answer:
Answer:
8x + 7y = 30 ( one solution)

Describe what a frequency table is what is used for
Answer:
A frequency table shows the distribution of observations based on the options in a variable. Frequency tables are helpful to understand which options occur more or less often in the dataset. This is helpful for getting a better understanding of each variable and deciding if variables need to be recoded or not.
Step-by-step explanation:
hope this helps! :)
The usage of frequency table is to create graphs such as histograms, bar charts, and pie charts to visualize the data.
We are given that;
The frequency table
Now,
A frequency table is a table that lists items and shows the number of times the items occur. It is a way of organizing data and summarizing how often each value or category appears in a dataset.
Frequency tables can be used for any type of variable, such as categorical, ordinal, or numerical.
Frequency tables can help us to understand the distribution of data, identify patterns, and compare different groups.
For example, suppose we have a dataset of 20 students' favorite colors. We can make a frequency table to show how many students prefer each color:
| Color | Frequency |
| ----- | --------- |
| Red | 5 |
| Blue | 7 |
| Green | 4 |
| Yellow| 2 |
| Pink | 2 |
Therefore, by the table answer will be to create graphs such as histograms, bar charts, and pie charts to visualize the data.

Which pair of rectangles are similar
Answer:
Its 2nd one
Step-by-step explanation:
189÷90=2.1
81÷90=0.9
1. Separate the number 58 into three parts so
that the second number is 2 less than the
first number which is one half the third
number.
Answer:
2nd number = 13
First number = 15
3rd number = 30
Step-by-step explanation:
Let
2nd number = 1/2x - 2
First number = 1/2x
3rd number = x
Total = 58
x + 1/2x + 1/2x - 2 = 58
x + x+x/2 = 58 + 2
x + 2/2x = 60
x + x = 60
2x = 60
x = 60/2
= 30
x = 30
2nd number = 1/2x - 2
= 1/2*30 - 2
= 15 - 2
= 13
First number = 1/2x
= 1/2*30
= 15
3rd number = x
= 30

A small town has two local high schools. High School A currently has 600 students
and is projected to grow by 65 students each year. High School B currently has 950
students and is projected to grow by 30 students each year. Let A represent the
number of students in High School A in t years, and let B represent the number of
students in High School B after t years. Write an equation for each situation, in terms
of t, and determine after how many years, t, the number of students in both high
schools would be the same.
Answer:
The senior class will have 100 members in the 13th year.
Step-by-step explanation:
Use the compound interest equation with a negative interest rate:
A = P(1 + r/n)^(n)(t)
Let n be 1 since we're looking for a specific year.
100 = 250(1 - 0.07)^t
100/250 = (0.93)^t
0.4 = (0.93)^t
t = 13 years
