Answers
Answer:
3x-4y=10
Step-by-step explanation:
y=(3/4)x-5/2
Standard form of the equation Ax+By=C, with A, B, and C integer numbers
The coefficient of "x" and the independent term are fractions. To simplify them, let's multiply both sides of the equation by 4:
4y=4 [ (3/4)x-5/2]
4y=4(3/4)x-4(5/2)
4y=(4/1)(3/4)x-(4/1)(5/2)
4y=[(4*3)/(1*4)]x-(4*5)/(1*2)
4y=(12/4)x-20/2
4y=3x-10
The two variables must be in the same side of the equation and the independent term in the other side, but the coefficient of "x" must be positive, then subtracting 4y and adding 10 both sides of the equation:
4y-4y+10=3x-10-4y+10
10=3x-4y
3x-4y=10

x = 10
Both angles measure 80°
—
Work:
the two angles are vertical angles, meaning that they are equal to each other, hence the equation will be this:
8x = x + 70
To solve, subtract x on both sides
7x = 70
Divide 7 on both sides to isolate the x
x = 10
Now, to find both of the angles measurement, plug in 10 for x.
10 + 70 = 80
8(10) = 80
Answer:
Equation:x+70=8x and both angles measure 80 degrees.
Step-by-step explanation:
Equation:x+70=8x
That is because vertical angles are congruent.
x+70=8x
-x -x
70=7x
x=10
Both angles measure 80 degrees.

PlS HElPPP I HAVE IT DUE TOMMOROWW BRAINLIEST FOR THE ONE
Answers
=======================================================
Explanation:
Multiply each visit count with their corresponding frequency.
Examples:
0*12 = 0 for the first row.1*366 = 366 for the second row2*53 = 106 for the third rowand so on...
I recommend making a third column like this
\(\begin{array}{|c|c|c|} \cline{1-3}\text{Visits} & \text{Frequency} & \text{Visits*Frequency}\\\cline{1-3}0 & 12 & 0\\\cline{1-3}1 & 366 & 366\\\cline{1-3}2 & 53 & 106\\\cline{1-3}3 & 52 & 156\\\cline{1-3}4 & 155 & 620\\\cline{1-3}5 & 243 & 1215\\\cline{1-3}\end{array}\)
That way you can keep track of all the results in an organized way.
Then add everything in the third column
0+366+106+156+620+1215 = 2463
Divide this sum over the total frequency (12+366+53+52+155+243 = 881) and we'll get the mean
2463/881 = 2.7956867
Rounding to one decimal place gets us to 2.8 as the final answer.

The much longer way to do this is to imagine 12 copies of "0", 366 copies of "1", 53 copies of "2", and so on. We'll have an extremely large data set of 881 items inside it. As you can see, this second method is definitely not recommended to actually carry out. Rather it's helpful to have this as a thought experiment to see why we revert to multiplication instead.
Eg: Imagine adding 155 copies of "4". A shortcut is to simply say 4*155 = 620

Area of five squares = 1289.09 square units
Perimeter = 194.6 units
Step-by-step explanation:
Area of square and perimeter:
First find the length of each square, then find the area of each square.
To find the area of five squares, add all the area of each square.
Side of square1 = 27 units
\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)
Area of square1 = 27*27 = 729 square units
Area of square2 = 18*18 = 324 square units
Area of square3 = 12*12 = 144 square units
Area of square4 = 8*8 = 64 square units
Area of square5 = 5.3*5.3 = 28.09 square units
Area of five squares = 729 + 324 + 144 + 64 +28.09
= 1289.09 square units
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)
= 90 + 42 + 28 + 18.7 + 15.9
= 194.6 units
the perimeter is 194.6 units
