Answer:
2x+7
Step-by-step explanation:
3x +(-x) = 3x - x, so it's 2x
12 + (-5) is the same situation, just being 12 - 5, so it's 7.
putting them together leaves you with 2x+7
In the attachment below I need you to find m∠DBC.
Answer:
m<DBC = 109
Step-by-step explanation:
8x-27=6x+7
8x=6x+34
2x=34
x=17
8(17)-27= 109
Answer: 109
Step-by-step explanation:
i'm not entirely sure of this answer as its been a while since ive done problems like this, however, i think the steps to solve are setting (8x-27) equal to (6x+7). Once you do that, you can solve for x. Substitute x into angle DBC to find the answer.
-15=5(3q-10)-5q
Solve the equation
Answer:
q = 3.5
Step-by-step explanation:
Start by distributing the 5
-15 = 15q - 50 - 5q
Combine like terms
-15 = 10q - 50
Add 50 to both sides
35 = 10q
Divide by 10 to isolate q
35/10 = q
q = 3.5
Answer:
q=3.5 or 4
Step-by-step explanation:
-15=5(3q-10)-5q
-5=15q-50-5q
-15+50=15q-5q
35=10q
Divide both sides by 10.
35÷10=10q÷10
3.5=q
Therefore,q= 3.5

One garden had 5 times as many raspberry bushes as a second garden. After 22 bushes are transplanted from the first garden to the second garden, the number of raspberry bushes in the gardens are the same. How many bushes did each garden have originally?
Please show work and no links or files! :)
To solve this problem form the system of equations as per statements given in the question then get the answer by solving them.
Number of bushes in garden one were 55 and in second garden 11 originally.
Let the number of raspberry bushes in one garden = x
And the number of raspberry bushes in second garden = y
Garden one has 5 times as many raspberry bushes as second garden,So the equation for the given statement will be,
x = 5y -------(1)
22 bushes were transplanted from garden one to the second, number of bushes in both the garden becomes same,Therefore, equation for this statement will be,
(x - 22) = (y + 22)
x - y = 22 + 22
x - y = 44 ------(2)
Substitute the value of x from equation (1) to equation (2)
5y - y = 44
4y = 44
y = 11
Substitute the value of 'y' in equation (1),
x = 5(11)
x = 55
Therefore, Number of bushes in garden one were 55 and in second garden 11 originally.

Answer: Y = 3500, X = 16
Step-by-step explanation:
Your maximum Y-value is 3000, or, the price of your car, so that could be the answer that's being looked for. However, it's always a good idea to leave a little extra space on the end of the graph so that you can show that your line ends instead of continuing onwards.
Your maximum X-value is 15, or, the number of months it would take to pay off the car (200 dollars per month, until you reach 3000 dollars), but again, it's always smart to leave a little buffer space so that you can see that the graph actually ends.
The answer your teacher wants is probably that the maximum Y-value should be 3000 and the maximum X-value should be 15, but if you have to actually graph this equation yourself and want it to be understood that your graph is a line segment and not a line (the difference being that a line is infinite and a line segment has two ends), you will want to show that by not ending the graph at the same spot as the line segment and instead extending it a little further.
7(2- 6x) = -196 I having trouble understanding this problem.
Answer:
x = 5
Step-by-step explanation:
7(2 - 6x) = -196
14 - 42x = -196
14 - 42x - 14 = -196 - 14
-42x = -210
-42x/-42 = -210/-42
x = 5
Answer:
5
Step-by-step explanation:
7(2 - 6x) = -196 Remove the brackets
7*2 - 7*6x = - 196
14 - 42x = - 195 Subtract 14 from both sides
-42x = - 196 - 14
-42x = - 210 Divide by 42
x = - 210 / - 42
x = 5
A theater charges $4 for each matinee
ticket. If it sells 360 tickets for a matinee
performance, how much does it take in?
Answer:
1,440
Step-by-step explanation:
Because 360*4=1,440
Answer:
$1440
Step-by-step explanation:
What you're going to want to do is multiply 4 by 36 at first. This is going to get you to 144. If you really wanted to break it down, you can multiply 4 by 3, place a zero at the end, multiply 4 by 6, and add the totals. Next, since the question is 4x360 and not 36, we will need to place a zero at the end of the product. This will get you 1440. And so, the answer is $1440.

Hello there!
We are given the equation:
[tex] \displaystyle \large{ |4x - 1| = 1}[/tex]
Definition/Property
[tex] \displaystyle \large{ |a| = \sqrt{ {a}^{2} } } \\ \displaystyle \large{ |a| = b \longrightarrow a = \pm b} \\ \displaystyle \large{ |a| = \begin{cases} a \: \: (x \geqslant 0) \\ - a \: \: (a < 0) \end{cases}}[/tex]
First, cancel the absolute value sign and write plus-minus beside 1.
[tex] \displaystyle \large{ |4x - 1| = 1} \\ \displaystyle \large{ 4x - 1 = \pm 1} \\ [/tex]
Break in two cases.
[tex] \displaystyle \large{ 4x - 1 = \begin{cases} 1 \\ - 1 \end{cases}} \\ \displaystyle \large{ 4x = \begin{cases} 1 + 1 \\ - 1 + 1 \end{cases}} \\ \displaystyle \large{ 4x = \begin{cases} 2 \\ 0 \end{cases}} \\ \displaystyle \large{ x = \begin{cases} \frac{2}{4} \\ \frac{0}{4} \end{cases}}[/tex]
Therefore, x = 0 or 1/2

Hi! I'm happy to help!
A square root, means:
√x=y
This means that:
x=y·y=√x·√x
When we have the square button, it causes everything to be multiplied by itself once.
√x²=x
Due to the fact that the squared symbol is outside of the parenthesis, it causes both the square toot of 2, and the square root of 3, to be squared.
Now that we know this, √2², and √3²= 2, and 3.
This is why we get 2+3.
2+3=5, which is pretty self explanatory.

The diagram shows a rectangle ABCD. The point A is (2, 14), B is (−2, 8) and C lies on the x-axis. Find
(i) the equation of BC,
(ii) find coordinates of C and D
Answer:
Step-by-step explanation:
since AB and BC are perpendicular so AB.BC=0, (scalar product)
AB=(-4, -6), and BC=(xc+2, yc-8)
AB.BC= -4x-8-6y+48 =0
so the equation of BC is 2x+3y-20=0
C is on the line BC, so 2xc+3yc-20=0, but yc=0, so xc=20/2=10
AB and CD are parallel, so det(AB, CD)=0
AB and AD are perpendicular so AB.AD=0
AB=(-4, -6) and CD =(x-10, y), AD= (x-2, y-14)
det(AB, CD)=0
x-10-y = 0 equivalent to x-y = -10
AB.AD=0
-4x+8-6y+84=0 equivalent to 2x+3y=44
let's solve
x-y = -10
2x+3y=44
-5y = -64, y = 64/5, x= -10+64/5=14/5
finally D(14/5, 64/5)

Answer:
Step-by-step explanation:
(g + 4) - 3g = 1 + g
(g + 4) - 3g = 1 + g
or, g + 4 - 3g = 1 + g
or, -2g + 4 = 1 + g
or, -2g - g = 1 - 4
or, -3g = -3
or, g = -3/-3
or, g = 1
The value of g is 1.

What is the solution to this equation?
2x + 3 (x - 10) = 45
A. x = 15
B. x = 3
C. x = 7
D. x = 11
ANSWER: A (x = 15)
Answer:
The value of x is 15
Step-by-step explanation:
2x + 3(x - 10) = 45
2x + 3x - 30 = 45
5x - 30 = 45
Now, Add 30 both sides we get,
5x - 30 + 30 = 45 + 30
5x = 75
Now, Divide 5 from both sides we get,
5x/5 = 75/5
x = 15
Thus, The value of x is 15
Hence, Option A is correct
