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.

A theater charges $4 for each matinee

performance, how much does it take in?
Answers
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.

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
Answers
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)

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! :)
Answers
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.

Find the unknown sizes of the angle
please answer fast
Answers
The opposite angles formed on an intersecting line are equal.
Here,
angle y + 10 = angle 2y - 80
Now,
y + 10 = 2y - 80
10 + 80 = 2y - y
90 = y
Therefore,
The angle y + 10 measures 100°.
Also, angle 2y - 80 measures 100°.
The other two angles measure 80° each.
