Answer:
No solution
Step-by-step explanation:
3 x + 6 = − 6+ 3 x
Move all terms containing 'x ' to the left side of the equation.
'6 = − 6 ' Since '6 ≠ − 6' , there are no solutions.

Solve each equations by substitution. y=2x
25x-y=9
Answer:
x=9/23 and y=18/23
Step-by-step explanation:
Substitute 2 x for y in 25x−y=9
25x−y=9
25x−2x=9
23x=9
23x/23=9/23
x=9/23
substitute 9/23 for x in y=2x
y=2x
y=2(9/23)
y=18/23
x= 9/23 and y=18/23
Tiki, Alan, and Hans sent a total of 102 text messages during the weekend. Hans sent 2 times as many messages as Alan. Tiki sent 6 more messages than Alan. How many messages did they each send ?
Answer:
Alan = 24, Tiki = 30, Hans = 48
Step-by-step explanation:
let x be the number of texts alan sent
[tex]x + 2x + x + 6 = 102\\4x + 6 = 102\\4x = 96\\x = 24[/tex]
Alan: 24
Tiki: 24 + 6 = 30
Hans: 24 * 2 = 48

Jose has saved $135 towards the purchase of a PlayStation 5. The total cost of the PS5 is $499. How much more money does Jose need to save?
Write an addition equation and solve.
Answer:
Let x be how much more money Jose needs to save.
135 + x = 499
x = 364
Jose needs to save 364 more dollars.
Let me know if this helps!
Answer:
364*
Step-by-step explanation:
499-135=314
364+ 135=499
I put 449 instead of 499 so now i feel foolish. But that's okayy.
Which of these sets is the null or singleton set
(a) A={x:x is not equal to x}
Answer:
(iii) C = {0}.
iv) The set of all triangles having four sides is a NULL ser
Step-by-step explanation:
Complete question
Identify the following sets as null set or singleton set.
(i) A = {x : x ∈N, 1 < x < 2}
(ii) B = The set of all even natural numbers which are not divisible by 2
(iii) C = {0}.
(iv) D = The set of all triangles having four sides.
A null set is a set that contains no element while a singleton set is. a set that has only one element
The set C ={0} has just one element which is zero. This shows that the set is a singleton set
Also a triangle only has 3sides. No triangle can have 4sides. Hence the set of all triangles having four sides is a NULL SET

Find the value of each variable in the circle to the right. The dot represents the center of the circle
Answers:
a = 68.5b = 90c = 43================================================
Explanation:
a = 137/2 = 68.5
I'm using the inscribed angle theorem. This says that the inscribed angle is half that of the arc it cuts off.
-------------------
b = 90 since any inscribed angle of a semicircle is always 90 degrees (Thales Theorem). This is a useful way to create right angles if all you have are a straight edge and compass.
--------------------
Note how the arcs c and 137 form a 180 degree semicircle, which means,
c+137 = 180
c = 180-137
c = 43

which equation represents the linear graph
ILL MARK BRAINLIST
Answer:
B
y=2x+4
Step-by-step explanation:
The y-intercept is 4, as the line passes through the y-axis only once, and at (0,4)
The format of a linear graph is y=mx+b where m is the slope and b is the y-intercept.
You can already tell that B is the only one with the y-intercept of 4.
The slope can be calculated quite easily, as we will start from (0,4) and make our way up to the next easily discernible point. The next most easily point seen is (2,8) so we will use the slope equation to find the slope. The equation is more or less like y2-y1 over x2-x1.
The y2 and x2 would be the (2,8) point because that is the second point on the line we are using. The x1 and y1 would be the first point (0,4). Now we will fill in the equation, which will look like 8-4 over 2-0 which will be 4 over 2, simplified to 4/2 and 2/1, being equal to 2.
The slope/m will be equal to 2, so the equation will look like
y=2x+4

PLZ HELP ME THIS IS 7th grade math
Answer:
The answer is: x = 18.
Step-by-step explanation:
1) That is a right angle, so it equals 90 degrees. You can add together the 'x'es that you see in the photo, and x + x +3x = 5x.
2) Set that equal to 90, so: 5x = 90.
3) Divide by 5 on both sides, to get x = 18.

y/1 = 36/x is this a direct variation or an inverse variation?
Answer:
Inverse variationStep-by-step explanation:
Direct variation:
[tex]\dfrac{y}{x}=constant[/tex]
Inverse variation:
[tex]xy=constant[/tex]
We have
[tex]\dfrac{y}{1}=\dfrac{36}{x}[/tex]
cross multiply
