Given:
[tex]\sf \dfrac{a\ -\ 3b}{a\ +\ 2b}\ =\ \dfrac{4}{3}[/tex]
To find: The value of a:b.
Answer:
[tex]\sf \dfrac{a\ -\ 3b}{a\ +\ 2b}\ =\ \dfrac{4}{3}[/tex]
Cross-multilpying,
[tex]\sf 3\ \times\ (a\ -\ 3b)\ =\ 4\ \times\ (a\ +\ 2b)\\\\3a\ -\ 9b\ =\ 4a\ +\ 8b[/tex]
Bringing the like terms together,
[tex]\sf 3a\ -\ 4a\ =\ 8b\ +\ 9b\\\\\\-a\ =\ 17b\\\\\\\dfrac{-a}{b}\ =\ 17\\\\\\\dfrac{a}{b}\ =\ -17[/tex]
Therefore, a:b = -17.
i have no idea what the answer, please help me
Answer:
43°
Step-by-step explanation:
-the interior angle of a triangle always adds up to 180°
- angles that form a straight line always adds up to 180°
- the angle at 75° has the angle of 105° to add up to 180°
- the triangle needs a full degree of 180, but only affs up to 137° (105° + 32°) so you have to subtract the 137° from the total amount you need(180°) which gives you the answer of 43°
Answer:
Step-by-step explanation:
it cant be 73° then it would look about the same size as 75°
and it cant be 15° cause it would look smaller than 32°.
so in my Opinion it looks like it would be 43°.

Carlos and his family are driving to California for vacation. The trip is 1,146 miles and they drive at an average speed of 56 mph. Which equation would give the number of miles remaining until they reach their destination, M, in terms of h, the number of hours they have driven? А. M= 1,146 + 56h
B. M= 56 - 1,146h
C. M= 56 + 1,146h
D. M= 1,146 - 56h
Answer:
D. M = 1,146 - 56h
Step-by-step explanation:
I beleive that this answer is the most reasonable because we arent adding miles to the trip we are taking away. Also subtracting from 56 would result in a negative answer and that really doen't make sense because they still have more miles to travel before they reach their destination.
Andre shot three arrows and they landed at (-5,4),(-8,7),and(1,6). What is his Total score? Explain your reasoning
I've attached the graph showing the colored regions of the archery target.
The scores for the colored regions are;
Yellow: 10 points
Red: 8 points
Blue: 6 points
Green: 4 points
White: 2 points
Answer:
16
Step-by-step explanation:
From the graph, At coordinate of (-5,4), the colored region is blue which means a score of 6 points.
From the graph, At coordinates of (-8,7), the colored region is red which means a score of 8 points
From the graph, At coordinates of (1,6), the colored region is white which means a score of 2 points
Thus, total score = 6 + 8 + 2 = 16
Step-by-step explanation:
Here are the scores for landing an arrow in the colored regions of the archery target.
Yellow: 10 points
Red: 8 points
Blue: 6 points
Green: 4 points
White: 2 points

Mike is mixing paint for his walls. He mixes
1/6 gallon blue paint and
4/9 gallon green paint in a large container.
What fraction represents the total amount of paint Mike mixes?
Answer: 11/18
=======================================================
Explanation:
We need to add the fractions, but first we need to get each fraction to have the LCD (lowest common denominator) of 18
18 is the LCM of the denominators 6 and 9
The fraction 1/6 turns into 3/18 when multiplying top and bottom by 3
The fraction 4/9 turns into 8/18 after multiplying top and bottom by 2
Therefore,
(1/6) + (4/9) = (3/18) + (8/18) = (3+8)/18 = 11/18
So Mike has a total of 11/18 of a gallon of paint when combining the two given amounts 1/6 a gallon of blue paint and 4/9 of a gallon of green paint.
anyone know this? cuz i'm confused
Answer:
y =37
x=12
z=131
Step-by-step explanation:
The angles of the left triangle are 59, 84 , y
They sum to 180
59+ 84+ y = 180
143 +y = 180
y = 180-143
y =37
The angles of the right triangle are 104,64,x
They sum to 180
104+64+x
168+x=180
x = 180-168
x=12
The angles of the middle triangle are x,y,z
They sum to 180
x+y+z
12+37+z = 180
49+z =180
z = 180-z
z=131
You know that the total measure of the angles in a triangle is 180 degrees.
You can use this to find angles x and y.
The angles of one of the triangles are x, 104, and 64. This means x would be 12.
104+64+x = 180
x = 180-104-64
x = 12
Use this same method to find y. The angles of the triangle y is in are 84, 59, and y. This means y is 37.
84+59+y = 180
y = 180-84-59
y = 37
Now you have x and y. The angles x, y, and z share one triangle. You can use this to find z.
x+y+z = 180
You know that x is 12 and y is 37.
12+37+z = 180
z = 180-12-37
z = 131
So...
x = 12
y = 37
z = 131

sean has to face a big problem but he becomes stronger as a result which saying best summarizes the change in Sean?
A.A switch in tie saves nine
B.be careful what you wish for
C.pride comes before a fall
D.every cloud has a silver lining
Please help me I WILL give brainless <33
Answer: D. every cloud has a silver lining
The cloud represents a dark, scary, or sad moment. This is in contrast to the sun which metaphorically represents energy and happiness. The cloud sometimes covers up the sun to cover up those happy moments so to speak.
Despite the cloud being present, there's a silver lining to the cloud which represents some positive aspect a person didn't expect to happen. In this case, the problem allows Sean to get stronger. So this is an opportunity for his growth.

PLEASE HELP I NEED IT I WILL MARK BRAINLIEST
Answer:
y = (1/12)x^2
Step-by-step explanation:
The vertex of this parabola is halfway between (0, 3) and the directrix, y = -3; that is, it's at (0, 0).
The applicable equation for this vertical parabola is 4py = x^2, where p is the distance between the vertex and the focus. Here that distance is p = 3.
Thus, 4py = x^2 becomes 4(3)y = x^2, or 12y = x^2, or y = (1/12)x^2.
Have a good day!

Graph the solution of 1/4x≤2. Please use a virtual graph or draw your own.
Answer:
The solution of [tex]\frac{1}{4}x \leq 2[/tex] is [tex]\mathbf{x\leq 8}[/tex]
Graph of the solution is attached in the figure below.
Step-by-step explanation:
We need to the graph the solution of [tex]\frac{1}{4}x \leq 2[/tex]
First we will solve to find value of x
[tex]\frac{1}{4}x \leq 2[/tex]
Multiply both sides by 4
[tex]\frac{1}{4}x\times 4 \leq 2\times 4 \\x\leq 8[/tex]
So, the solution of [tex]\frac{1}{4}x \leq 2[/tex] is [tex]\mathbf{x\leq 8}[/tex]
Graph of the solution is attached in the figure below.
The graph contains both number line and on graph paper also.

-2.8%
ascending means from smallest to biggest so the answer would be 0.053
What is the slope of the line that passes through the following g points

Answer:
2.5
Step-by-step explanation:
The slope of the line is; [tex]\frac{rise}{run}[/tex] and can be found using the formula;
[tex]\frac{y_{2} - y_{1}}{x_{2}-x_{1}}[/tex]
Given the points;
( 6, 3 ) and ( 4, -2)
Substitute the points in and solve;
[tex]\frac{(-2) - (3)}{(4) - (6)}[/tex]
[tex]\frac{-5}{-2}\\\\\frac{5}{2}\\\\= 2.5[/tex]
