Answer:
-9
Step-by-step explanation:
This is a find the x equation!
4(x+9)=x+9
First we'll multiple the 4 into the paranthatsis
4x+36 = x +9
then we'll group the Xs together on one side, and the normal nubers (make sure to make sure the signs are right when moving them across the = sign)
3x= -27
x = - 9
Given 2x+6=12 prove x=3
Answer:
3times 2 + 6=12

BRAINLIEST!! The product of two numbers is 144, but their sum is –24. What are these two numbers?
A. -22 and -2
B. -12 and -12
C. -20 and -4
D. -10 and -14
Answer:
B .-12 and -12
Step-by-step explanation:
it is because when we multiply two -digit the answer is in +
so like in the same -12 * -12=144
And when we add the digit we get -24
Hence, it is proved
Find AC if AB = 1, AC = 2x + 26, and BC = x + 16
Answer:
8
Step-by-step explanation:
AC=AB+BC
2X+26=1+x+16
2x-x=1+16-26
X= - 9
Now, AC=2X+26
=2*-9+26
= - 18+26
=8
4x - y/2y +x
------- x=3 y=3
Answer:
B
Step-by-step explanation:
4x - y = 4*3 - 3 = 12 - 3 = 9
2y + x = 2*3 + 3 = 6 + 3 = 9
(4x - y) / (2y + x ) = 9/9 = 1
Convert 491 into binary number
Answer:
111101011 subscript 2
Step-by-step explanation:
491 / 2 = 245 , 1 remainder
245 / 2 = 122 , 1 remainder
122 / 2 = 61 , 0 remainder
61 / 2 = 30 , 1 remainder
30 / 2 = 15 , 0 remainder
15 / 2 = 7 , 1 remainder
7 / 2 = 3 , 1 remainder
3 / 2 = 1 , 1 remainder
1 / 2 = 0 , 1 remainder
Now, we're going to put the remainders together in reverse order to get the final answer.
111101011 ---> this is the final solution
See the image below for how you would write 111101011 subcript 2.
Answer:
111101011 is the binary form of 491

If C is between B and D with BC = 8x+8, Cd = 6x-28 and BD = 10x + 24, Then find CD
Whats CD
Answer:
CD = 38
Step-by-step explanation:
Answer
BC = CD
And,
BC + CD = BD
8x + 8 + 6x - 28 = 10x + 24
14x - 20 = 10x + 24
14x - 10x = 24 + 20
4x = 44
x = 44/4
x = 11
CD = 6(11) - 28
66 - 28
38
Answer:
CD = 38
Step-by-step explanation:
We know that BC and CD will add up to equal BD so we can create a equation and solve for x.
(8x + 8) + (6x - 28) = 10x + 24
~Combine like terms
14x - 20 = 10x + 24
~Add 20 to both sides
14x = 10x + 44
~Subtract 10x to both sides
4x = 44
~Divide 4 to both sides
x = 11
~Now substitute into CD
6(11) - 28
66 - 28
38

Find the midpoint of the two points (8,-2) and (-4,6).
a (9,7)
b (2,2)
c (9,2)
d (2,8)
Answer:
B
Step-by-step explanation:
To do that we use the formula: (x1 + x2) / 2 and (y1 + y2) / 2 to get (x,y) coordintaes of the mid-point
Therefore
(8 + (-4) ) / 2 , (-2 + 6) / 2
= 2,2

At a movie theater, Ellie paid $8 for her ticket.Candy at the theater is 3.25.she had a total of $25 to spend. What is the maximum number of candies she could buy.
Answer:
Step-by-step explanation:
Answer is 5 candies.
$25 is her total amount so you need to subtract the $8 that she paid for her ticket with.
The answer to that subtraction is $17.
With $17, you divide by $3.25 (price of candy) to get the number 5.2. Except, you can't buy a small bit of a candy, so you would be able to buy 5 in total.

Answer:
60%
Step-by-step explanation:
You see how many answers she got got right and to do that you subtract 170-68 and get 102. That's how many she answered correctly. Then you need to find the percentage and to do that you divide 102 by 170 which gives you 0.6, which can be read as 60%. Hope that helps! :)

Find the measures. Plz help i’ll give brainliest
Answer:
x = 61°
Step-by-step explanation:
Since the angles of 125° and 64° + x° are opposite each other in the same intersecting lines, they are equal.
Therefore, we could say that:
[tex]125 = 64 + x[/tex]
Now all we have to do is solve for x, by subtracting 65 from both sides of the equation:
[tex]125-64 = 64 + x-64\\x = 125-64\\x=61[/tex]

Find the measure of the side of the right triangle whose length is designated by a lowercase letter. (see attachment)
Please explain step-by-step.
Answer:
a≈18 cm
Step-by-step explanation:
we have given:
an angle,
the adjacent side and
we need to find:
the opposite side
we know that the definition of
tan of an angle = opp. side/ adj. side
tan 61° = a/ 10
multiply both sides by 10
10 * tan61° = a
18.04047755 = a
18 ≈ a
please help ASAP.. did I get it right or no ?? I put 96 if anybody can help please do
Hi! I'm happy to help!
Our net is composed of three shapes. Two congruent circles, and one rectangle. Our rectangle is 12cm by 2cm. Multiplied together, our rectangle has an area of 24cm².
We have our circle equation: A=[tex]\pi[/tex]r². It said to use 3 for pi, so our equation can be A=3(r²)
Radius is always half the length of our diameter. Our diameter is 4cm, so our radius will be 2cm.
Now, let's insert our values:
A=3(2²)
Now, let's solve:
A=3(4)
A=12
So, our area for one of the circles is 12cm². Since our circles are congruent, they will have the same area. Now, we have all 3 areas of all the shapes.
24+12+12=48cm²
Now, we need to name the figure. This is a net of a 3 dimensional shape. Since the net has circles on opposite sides, the rectangle must wrap around the circumference of both circles. This means that the 12cm must be equivalent to the circumference of the circle. Our circumference is 2[tex]\pi[/tex]r, or 2(3)(2), which is 12. So, with congruent circles on top and bottom, and a rectangle wrapping around, this seems to be a cylinder.
So, our Total Surface Area is 48cm², and the figure is a cylinder.
I hope this was helpful, keep learning! :D
