please some help! don't just comment just to comment i really need help
by the Angle sum property of triangle,
55+75+(-6+7x) = 180
=> 130 +(-6+7x) = 180
=> (-6+7x) = 180-130
=> (-6+7x) = 50
=> 7x = 50+6
=> 7x = 56
=> x= 56/7
=> x = 8

60% of what number is 348?
Answer:
208
Step-by-step explanation:
this is what I did. 348×.6
60% of 580 is 348 is the answer you're looking for
If you divide .6 by 348 you get 580.
To check your answer, you can do .4 (40%) multiplied by 580 to get 232
232+348=250 which is 100%
thats the problem the words say. Write an expression in simplest form that represents the perimeter of the polygon
Answer:
(29x + 9)
Step-by-step explanation:
Perimeter of a polygon = Sum of measures of all sides of the polygon
Therefore, Perimeter of the given polygon = (9 + 12x + 2x + 2x + 12x + x)
= (9 + 29x)
Expression (29x + 9) will represent the perimeter of the polygon.

Answer:
Volume of the prism = 280 ft^3
Step-by-step explanation:
Recall that the volume of a prism is given by the following formula:
Volume = B * H
where B is the area of the base (in our case a right angle triangle), and H is the prism's height (in our case 16 ft)
Then we estimate the area of the triangle at the base as base* height/2 :
Area triangle = 5 * 7 / 2 = 35/2 ft^2
and multiply by the prism's height to get its volume:
Volume = 35/2 * 16 = 280 ft^3

Which of the following is true about a parallelogram?
The diagonals are equal.
All sides are congruent.
The diagonals bisect each other.
The diagonals are perpendicular.
Answer:
The diagonals bisect each other.
Step-by-step explanation:
Not all diagonals of a parallelogram are equal.
The only quadrilaterals with all four sides being congruent are rhombus and squares so parallelogram is wrong.
The diagonals of a parallelogram bisect each other.
The diagonals of a parallelogram are only perpendicular when it is a square.
If one line has a slope of -5/4 what would the slope of a line
parallel to that line?
Answer:
[tex]-\frac{5}{4}[/tex]
Step-by-step explanation:
Parallel lines always have equal slopes. Therefore any parallel line to a given line will share the same slope.
Answer:
-5/4
Step-by-step explanation:
Parallel lines have the same slope but a different y intercepts, because if you think about parellel lines, they'll never intersect-- if two lines have the same slope, that means they won't be able to intersect. However, if they have the same slope, they would be coinciding (the same). That's why the y intercepts are different.
Since the slope of the first line is -5/4, the slope for the line parallel to it would also be -5/4
hope this helps!

Y is inversely proportional to x, when Y = 7, x = 4.
True or False: the constant of proportionality, k, is 20.
Answer:
The given statement Y = 7, x = 4 is False.
Step-by-step explanation:
We are given:
Y is inversely proportional to x, when Y = 7, x = 4.
We need to tell if the statement is True or False: the constant of proportionality, k, is 20.
Y is inversely proportional to x
We can write it as: [tex]y\:\alpha \:\frac{1}{x}\\y=\frac{k}{x}[/tex]
Now, we need to check when Y=7, x = 4 is true or false
We are given k = 20
Now, I can find value of y, by putting values of k and x in the equation:
[tex]y=\frac{k}{x}\\y=\frac{20}{4}\\y=5[/tex]
When we put x = 4, and k =20, we get Y=5 and not Y=7
So, The given statement Y = 7, x = 4 is False.
Factor completely 4x^2 − 8x − 60.
A. (4x-20)(x+3)
B. 4(x-5)(x+3)
C. (4x-4)(x+15)
D. 4(x-1)(x+15)

PLEASE HELP Which statement completes step 5 of the proof?
Step 1 segment KL is parallel to the y-axis, and segment JL is parallel to the x-axis.
Step 2 ΔJKL was rotated 90° clockwise to create ΔJ'KL'. Point K did not change position, so it remains point K. Therefore, ΔJKL ≅ ΔJ'KL'.
Step 3 segment K L prime is perpendicular to the y-axis, and segment J prime L prime is perpendicular to the x-axis.
Step 4 segment JK lies on line f and has a slope of 3.
Step 5 ?
Step 6 The product of the slopes of segment JK and segment J prime K is −1; therefore, lines f and g are perpendicular.
Answer:
Segment J’K lies on line g and has a slope of -1/3
