What is the solution to the equation 4(2-x)=5x-17
Answer:
x = 25/9 or 2.777777778
Step-by-step explanation:
4(2-x) = 5x - 17
8 - 4x = 5x - 17
+4x +4x
8 = 9x - 17
+17 +17
25 = 9x
25/9 = x
x = 2.777777778 or 25/9

What is a system of linear equations?A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.
It is given that in a coordinate grid with 2 lines. The first line labelled f(x) passes through (-3, 3), (0,2), and (3, 1). The second line labelled g(x) passes through the points at (-3, 0) and (0, 2).
Plotting the two lines by using the points on the graph. After plotting the points there will be two lines that will intersect at the point ( 0, 2 ). Then the solution of the equation is ( 0,2).
Therefore, the solution to the system of linear equations is (0,2). The correct option is C.

Step-by-step explanation:
Answer:
x+4
Step-by-step explanation:
This is because the multiplicative inverse of 5 is the reciprocal, or 1/5. This is then multiplied (distribution) to (5x+20), simplifying to x+4.
Given f(x) = 5(x + 1) + 16 , what is the value of x when f(x) = 1 ?
Answer:
x = -4
Step-by-step explanation:
1=5(x+1)+16
1=(5)(x)+(5)(1)+16 (Distribute)
1=5x+5+16
1=(5x)+(5+16)(Combine Like Terms)
1=5x+21
5x+21=1
5x+21−21=1−21
5x=−20
5x/5=−20/5
x=−4
Answer:
value of x is -4
Step-by-step explanation:
All you need to do is replace f(x) for 1.
1 = 5(x+1) + 16
backwards solve;
1 = 5x+5 +16
1=5x+21
1-21=5x
-20=5x
x=-4
That's all.
If it asks you if x=1, then just plug in 1 where ever x is. f(x) is symbolic of y.

You have $90 and your brother has $120. You are saving $18 per week
and your brother is saving $15 per week. How many weeks will it take for
you and your brother to have the same amount of money saved? *
10 weeks
1 week
5 weeks
12 weeks
Answer:
10 weeks
Step-by-step explanation:
Let's set an equation for you and your brother.
You have $90 plus $18 for every week you save (x).
90+18x
And your brother has $120 plus $15 dollars per week that he saves (x)
120+15x
You want to have the sum of the money equal so combine the two concluded statements
90+18x=120+15x
Arrange them so that you have like terms on each side
90+18x-15x=12+15x-15x
90+3x=120
90-90+3x=120-90
3x=30
x=10
"x" is our number of weeks you and your brother save so the answer is 10 weeks
Just to be sure you can use our equation and plug 10 for every time you see x to make sure our answer is right.
Find m∠MON
I have a hard time with theses
Answer:
m∠MON = 15°
Step-by-step explanation:
The given parameters are;
m∠LON = 77°
m∠LOM = 9·x + 44°
m∠MON = 6·x + 3°
By angle addition postulate, we have;
m∠LON = m∠LOM + m∠MON
Therefore, by substituting the known values, we have;
∴ 77° = 9·x + 44° + 6·x + 3°
77° = 9·x + 44° + 6·x + 3° = 15·x + 47°
77° = 15·x + 47°
77° - 47° = 15·x
15·x = 77° - 47° = 30°
15·x = 30°
x = 30°/15 = 2°
x = 2°
Given that m∠MON = 6·x + 3° and x = 2°, we have;
m∠MON = 6 × 2° + 3° = 12° + 3° = 15°
m∠MON = 15°.

Bob’s soup uses 18 drops of chili oil for every 4 cups of chicken broth. Yvonne wants her soup to have a weaker chili flavor than Bob’s soup. Which mixture should Yvonne use? A 18 drops of chili oil for every 2 cups of chicken broth
B 18 drops of chili oil for every 5 cups of chicken broth
C 20 drops of chili oil for every 4 cups of chicken broth
D 22 drops of chili oil for every 4 cups of chicken broth
Answer:
Yvonne should pick mixture B which has a lesser concentration of chili oil.
Step-by-step explanation:
Bob's soup concentration = 18 drops / 4 cups = 9 drops / 2 cups = 4.5 drops/cup
A. 18 / 2 = 9 drops/cup which is a greater concentration
B. 18 / 5 = 3.6 drops/cup which is a lesser concentration
C. 20/ 4 = 5 drops/cup which is a greater concentration
D. 22/ 4 = 5.5 drops/cup which is a greater concentration
What is the equation of the line that passes through the point (4,−2) and has a slope of -2
Answer:
y = -2x + 6

Point slope form is y - y1 = m(x-x1)
y - (-2) = -2(x-4)
y + 2 = -2x + 8
y = -2x + 6

Shannon is making identical balloon arrangements for a party. She has 32 maroon balloons, 24 white balloons, and 16 orange balloons. She wants each arrangement to have the same number of each color. What is the greatest number of arrangements that she can make if every balloon is used?
Answer:
8
Step-by-step explanation:
Given that:
Number of white balloon = 24
Number of maroon Ballon = 32
Number of orange Ballon = 16
To obtain the greatest number of arrangements ;
Find the greatest common factor of 24, 16 and 32
Factors of ;
24 = 1, 2, 4, 6, 8, 12, 24
16 = 1, 2, 4, 8, 16
32 = 1, 2, 4, 8, 16, 32
Hence, the greatest factor common to all three is : 8
Hence greatest number of arrangement that can be achieved is 8

Step-by-step explanation:
Use a^2 - b^2 = ( a - b) (a + b)
a = x
b =
[tex]b = \sqrt{3} [/tex]
Help solve equations by completing the square
[tex]x^2+10x+22=13\\x^2+10x+22-13=0\\x^2+10x+9=0\\[/tex]
Now completing the square.
[tex](x^2+10x)+9=0\\(x^2+10x+25)+9-25=0\\(x+5)^2-16=0\\(x+5)^2=16[/tex]
(x+5)² = 16 is the rewritten equation... For first question btw.
For the solutions to the equation -
[tex]x+5=\sqrt{16},-\sqrt{16} \\x+5=4,-4\\x=4-5,-4-5\\x=-1,-9[/tex]
x = -1,-9 is the solution, for the second question.
Peter scored a total 44 points on 9 math quizzes. What score does Peter need on his tenth and final quiz in order to have a final quiz average of 5 ?
Answer:
Number of points need = 6 points
Step-by-step explanation:
Given:
New average = 5
Points peter has = 44
Total quiz play = 9
Find:
Points required for average of 5
Computation:
Total number of match = 9 + 1
Total number of match = 10
Average points = 5
Assume;
Number of points need = x
So,
Average points = [Total points] / Total number of match
5 = [44+x] / 10
50 = 44 + x
x = 6
Number of points need = 6 points
The score does Peter needs on his tenth and final quiz in order to have a final quiz average of 5 is 6 and this can be determined by using the formula of average.
Given :
Peter scored a total of 44 points on 9 math quizzes.
The following steps can be used in order to determine the score of the tenth quiz:
Step 1 - The formula of average can be used in order to determine the score of the tenth quiz.
Step 2 - According to the given data, Peter scored a total of 44 points on 9 math quizzes. Now, let the score of the final tenth quiz be 'x'.
Step 3 - The average of the 10 quizzes is given by:
[tex]\dfrac{44 + x }{10}=5[/tex]
Step 4 - Simplify the above expression in order to determine the value of 'x'.
50 = 44 + x
x = 6
