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

i need help with 4=2/3(2x-9
Answer:
x=15/2
Hope it helps :)
Answer:
x = 7.5
Step-by-step explanation:
4 = 2/3 (2x - 9)
4 = 4/3x - 6
4 + 6 = 4/3x - 6 + 6
10 = 4/3x
10 x 3/4 = x
x = 7.5

Find the distance between the two points rounding to the nearest tenth (if necessary).

Write each decimal number as a fraction or mixed number in simplest form?
You're letting x = 0.325325325…, which means
1000x = 325.325325325… (or 325.325, but pretend the underline is actually an overline)
Then the next box you'd fill in with 0.325325325… (or 0.325).
Subtracting these, you have
1000x - x = 325.325325325… - 0.325325325…
999x = 325
Finally, solving for x gives
x = 325/999

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

(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.
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.

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.

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)

-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
