Answer:
x=2.5 thas the answer
Step-by-step explanation:
The sum of two numbers is 48. If the second number is 6 less than the first, what
is the value of EACH of the numbers?
Answer:
let the first no. be x
then the second no. = x - 6
their sum is 48
therefore,
[tex] = > x + (x - 6) = 48 \\ = > 2x = 48 + 6 \\ = > 2x = 54 \\ = > x = \frac{54}{2} \\ = > x = 27[/tex]
The value of first no. = x = 27
The value of second no. = x - 6 = 27 - 6
= 21
1) The standard form of a linear equation is written as .
ax + by=c
a. Write the equation in slope-intercept form( y= mx + b)
b. Write the slope, y-intercept form of (a).
PLS HELP
Answer:
[tex]\displaystyle y=-\frac{a}{b}x+\frac{c}{b}[/tex]
Step-by-step explanation:
The equation of the line, expressed in slope-intercept form is:
[tex]y=mx+y_o[/tex]
Where m the slope and yo the y-intercept.
Since we are given the line in standard form:
ax+by=c
To find the slope-intercept form, we just solve it for y:
[tex]\boxed{\displaystyle y=-\frac{a}{b}x+\frac{c}{b}}[/tex]
Comparing the last equation with the slope-intercept form:
[tex]\displaystyle m=-\frac{a}{b}[/tex]
[tex]\displaystyle y_o=\frac{c}{b}[/tex]
Answer:
ax + by = c
-ax -ax
by=ax+c
then dived both sides by b to get y by itself
y= a/bx +c

The graph shows the relationship between time and the number of soda bottles a machine can make. Use the points (4,112) and (6,168) to find the number of soda bottles the machine can make each minute.
Using y to represent number of bottles filled in x minutes, y = 250x.
This is rather basic, and I urge you to think about it so that it's very clear to you, and you will be able to do similar problems on your own in the future.
The graph will be a straight line passing through the origin (0,0).

Step-by-step explanation:
Mr Ramos is going to build a square-shaped room onto his house. Mr. Ramos wants the room's length to be as close to 10 ft as possible. Which area should his room have to give him the side length closest to 10?
Answer:
100ft²
Step-by-step explanation:
The problem here is to find the area of the room that will give a length of 10ft.
Note;
The room is a square room.
Now let us solve this problem;
Area of a square is:
Area = L²
Where L is the length of the room;
So the area of the room is;
Area = 10² = 100ft²
The area of the room that will give a length of 10ft is 100ft²
2(9 + 4x) + 6(2 - x) = 7x. i need help asap pleasee
Step-by-step explanation:
18 + 8x + 12 - 6x = 7x
30 + 2x = 7x
30 = 7x - 2x
30 = 5x
Divide both sides by 5

move vertices A B and C to modify the original parallelogram. As you change the parallelogram, notice what happens to the diagonals. How does moving the vertices affect the relationship between the diagonals that you noted in question 2?
Moving the vertices does not affect the relationship between the diagonals. They bisect each other in all cases.
Answer:
Despite changing the vertices, the opposite sides and opposite interior angles of the parallelogram remain equal.

10. X = 2.75
11. X = 1.61
Hey there, I have the steps listed below but what is the problem asking, I cannot solve it unless it explains the problem. Thank you!
Step-by-step explanation:
10. 5x + 10 + 11x + 2 = 56
16x + 12 = 56
16/16x = 44/16
X = 2.75
11. -1 + 8x + 18x + 5 = 46
26x + 4 = 46
26/26x = 42/26
X = 1.61

Problem 10
Answers:x = 11angle UTS = 65angle AUT = 123-----------------------
Explanation:
The remote interior angles UTS and TSU add to the exterior angle AUT. This is because of the remote interior angle theorem. The interior angles you add cannot be adjacent to the exterior angle.
(angle UTS) + (angle TSU) = angle AUT
(5x+10) + (58) = 11x+2
5x+10+58 = 11x+2
5x+68 = 11x+2
68-2 = 11x-5x
66 = 6x
6x = 66
x = 66/6
x = 11
Use this x value to find that...
angle UTS = 5x+10 = 5*11+10 = 65
angle AUT = 11x+2 = 11*11+2 = 123
==========================================
Problem 11
Answers:x = 4angle CDB = 31angle WBC = 77-----------------------
Explanation:
We'll use the same theorem as before
(angle BCD) + (angle CDB) = angle WBC
(46) + (-1+8x) = 18x+5
46-1+8x = 18x+5
8x+45 = 18x+5
45-5 = 18x-8
40 = 10x
10x = 40
x = 40/10
x = 4
angle CDB = -1+8x = -1+8*4 = 31
angle WBC = 18x+5 = 18*4+5 = 77
One gram of protein contains 4 calories. One gram of fat contains 9 calories. A snack has 80 calories from x grams of protein and y grams of fat. 80= 4x + 9y
If there are 6 grams of fat in the snack, how many grams of protein are there? Show your reasoning.
Answer:
6,5g of protein
Step-by-step explanation:
80=4x + 9y
y=6 ( "6 grams of fat")
so: 80=4x+9.6
80-54= 4x
26/4=x
x(protein)= 6,5
Answer:
6.5 grams
Step-by-step explanation:
To find the value of x that corresponds to the given value of y, put that y-value into the equation and solve for x.
80 = 4x +9·6
26 = 4x
26/4 = x = 6.5
There are 6.5 grams of protein in the snack.
Write each set in the indicated form. If you need to use "" to indicate a pattern, make sure to list at least four elements of the set. As you answer below, remember that the natural numbers are just the counting numbers. This means that is not a natural number, and negative numbers are not natural numbers either.
Complete question is;
Write each set in the indicated form.
If you need to use "..." to indicate a pattern, make sure to list at least four elements of the set.
As you answer below, remember that the natural numbers are just the counting numbers. This means that is not a natural number, and negative numbers are not natural numbers either.
(a) Roster form: {6,8,10,12,...}
Descriptive form:
(b) Descriptive form: The set of natural numbers greater than or equal to 3 and less than or equal to 6.
Roster form:
Answer:
A) Descriptive form: A set of even natural numbers that are greater than or equal to 6.
B) Roster form: {3, 4, 5, 6}
Step-by-step explanation:
A) We are given that the roster form is;
{6,8,10,12,...}
Now, the descriptive form is just a statement that describes the given roster form.
Now, we can see they are all even natural numbers and the least is 6 while after 12,we can see that the set continues.
Thus;
Descriptive form: A set of even natural numbers that are greater than or equal to 6.
B) We are given that the descriptive form is the set of natural numbers greater than or equal to 3 and less than or equal to 6.
This means the least number in the set is 3 while the highest number is 6.
Thus,the roster form is;
Roster form: {3, 4, 5, 6}

does the table below show a proportional relationship
Answer:yes
Step-by-step explanation:
During a musical an orchestra is playing. As the music plays, the volume changes in the beginning of the piece can be modeled by the equation s = 10│x - 4│+ 50 where s represents the sound level in decibels and x represents the number of measures of music played. Explain in words each step to find the following question:
At what number(s) measures played would the sound level be at 80 decibles?
( I need the answers, plus the steps please and thank youuu :)
Answer:
Kindly check explanation
Step-by-step explanation:
Given the model:
s = 10│x - 4│+ 50
s represents the sound level in decibels and x represents the number of measures of music played
To find x at s = 80
The equation becomes /
80 = 10│x - 4│+ 50
Subtract 50 from both sides of the equation
80 - 50 = 10 |x - 4| + 50 - 50
30 = 10 | x - 4 |
Divide both sides by 10
30/10 = 10|x - 4| / 10
3 = |x - 4|
|x - 4| is an absolute value expression
±3 = |x - 4|
x = 3 + 4 = 7
x = - 3 + 4 = 1
