Answer:
the answer is a = -4
Step-by-step explanation:
pls mark brainliest
Answer:
a = -4
Step-by-step explanation:
To find a, we need to get the variable on one side of the equation. So first we distribute.
-3a+5=a-6a-3 Now we subtract 5 from both sides and add the a to the -6a
-3a=-5a-8 Now we add 5a to both sides
2a=-8 And lastly divide both sides by 2
a= - 4
I hope this helps and please add me as brainliest! Thanks! <3

Find the value of x acellus
Help
Answer: x = 3
because ΔABC has BD is the bisector of ∠ABC
=> AD/AB = DC/BC
⇔ x/6 = 4/8
⇔ x/6 = 1/2
⇔ x = 6.1/2
⇔ x = 3

PLS HELP HW DUE IN 2MIN!!!!
Step by step pls I’ll make u brainly
Answer:
a = 6
Step-by-step explanation:
120 = 3 + 3(7a - 3) (by PEDMAS, expand parentheses first by distributive property)
120 = 3 + 7a(3) - 3(3)
120 = 3 + 21a - 9
120 = 21a - 6 (add 6 to both sides and rearrange)
21a = 120 + 6
21a = 126 (divide both sides by 21)
a = 126/21
a = 6
Step-by-step explanation:
120-(3+3*(7*a-3))=0
Step by step solution :

Equations which are never true:
4.1 Solve : -21 = 0
This equation has no solution.
A a non-zero constant never equals zero.

Add 6 to both sides of the equation :
a = 6
One solution was found :
a = 6
Simplify this expression (xy^4)^6
Answer:
x^6*y^24
Step-by-step explanation:
This will become:
[tex]x^6*(y^4)^6[/tex]
Next, multiply the exponents for y:
x^6 * y^24
So the answer is x^6*y^24
If DF and GI are parallel lines and mGHE = 47°, what is mIHE?
Answer:
mIHE should be 133°
Step-by-step explanation:
A line is 180°, so, if you take 47° off you're left with 133.
Giving you an answer of 133°.
what is the measure of the missing angle?
Answer:
137 degrees
Step-by-step explanation:
By using the fact that a triangle contains 180 degrees and angles made by the same lines are congruent we can find out that the top angle in the first triangle is 45 degrees. We can then figure out that the missing angle in that same triangle is 75 degrees by adding 45 and 60 and subtracting that from 180. Then we add that 75 degrees to 68 degrees to get 143 degrees which we can use to discover that the corner of the triangle that connects to the other triangle is 37 degrees. From there we know that triangles contain 180 degrees, so the remaining value is 43 and with this we can discover that the value of the asked for angle is 137 degrees.

The circle below is centered at (-3, 2) and has a radius of 3. What is its
equation?
A. (x-3)2 +(- 2)2 = 9
B. (x+3)2 + (y-2)2 = 3
C. (x+3)2 + (y-2)2 = 9
D. (x-3)2 + (y-2)2 = 3
Answer:
C
Step-by-step explanation:
The equation is (x-a)^2 + (y-b)^2 = r^2
(x+3)^2+(y-2)^2 = 9
Lea wants to save money on a new computer. At the store near her, the computer she wants is listed at a regular price of $2000.

Hello! Some assistance with this question would be really helpful (:
The mode is the most common number in the data set. If there are two numbers that appear frequently (in this case 69 and 73) then this data set has two modes.
The median is the middle of the set of numbers (line them up from top to bottom).
In this case it should look something like:
68 68 69 69 69 69 70 70 71 72 72 73 73 73 73 75 78
If the whole list of numbers are even, then pick the two middle numbers and find their average. If it is odd, just choose the middle most number.
Mean is the average of all numbers. If you have 5 numbers, add them all up and divide by 5. If you have 10 numbers, add them all up and divide by 10.

Step-by-step explanation:
Two straight lines have equations y = p x + 4 y = p x + 4 and p y = q x − 7 p y = q x − 7 , where p p and q q are constants. The two lines meet at the point ( 3 , 1 ) ( 3 , 1 ) . What is the value of q q ?
Answer:
q = [tex]\frac{8}{3}[/tex]
Step-by-step explanation:
The point of intersection (3, 1 ) is the solution to both equations
Using
y = qx - 7 and substituting x = 3, y = 1
1 = 3q - 7 ( add 7 to both sides )
8 = 3q ( divide both sides by 3 )
[tex]\frac{8}{3}[/tex] = q

There are 4 floors of classrooms in a school. One classroom takes 16 of each floor. How many classrooms are there in all on the 4 floors?
Answer:
takes 16 what??
if u tell me i can help u x
Step-by-step explanation:
Answer:
24
Step-by-step explanation:
If there are 4 floors and each classroom takes 1/6 of a floor, there are 6 classrooms per floor. Then, since there are 4 floors, you do 6 classrooms X 4 floors, which equals 24 classrooms.

Solve 8x – 5 = 23 + 4x.
Answer: X equals 7
Step-by-step explanation:
Answer:
7
Step-by-step explanation:
First you want to simplify the equation
8x + (-5) = 23 + 4x
-5 + 8x = 23 + 4x
Then solve for x, but before we do that we !!!must!!! move all terms that have x to the left. Everything else would go to the right.
So we add -4x to both sides ..
-5+ 8x + (-4x) = 23 + 4x + (-4x)
-5 + 4x = 23 + 4x + (-4x)
-5 + 4x = 23 +0
-5 + 4x = 23
Then add 5 to both sides of the equation:
-5 + 5 + 4x = 23 + 5
0 + 4x = 23 + 5
4x = 23 + 5
4x = 28
Then divide each side by 4:
x = 7
And there you have it. The answer is 7. Hope this helps! :)

PLEASE ONLY ANSWER WITH A PROPER ANSWER FOR EACH ONE...NOT JUST FOR POINTS-Thank you so muchhhh
Answer:
[tex]x > \frac{1}{2}[/tex]
Step-by-step explanation:
For the first one, in any triangle, we have the sum of two sides is greater than the third side. Hence, we have 3 inequalities: [tex]4x+3>2x+1, 5x+1>x+3, 3x+4>3x[/tex], which give us [tex]x>-1, x>\frac{1}{2},4>0[/tex]. We conclude that [tex]x>\frac{1}{2}[/tex].
For the second question, we have [tex]AB<BP+AP=2x[/tex], and similarly we can show that [tex]AC, BC<2x[/tex]. Hence, [tex]AB+BC+AC<6x[/tex].
The third question is not very clear.
