Answer:
39
Step-by-step explanation:
5x-20=2x+10 (opposite sides of parallelogram are equal)
5x-2x=10+20
3x=30
x=30/3
x=10
Now putting the value of x in 4x-1, we get
(4×10)-1
= 40-1
= 39
Which math PROPERTY is this? If 12 = 17 - 5, then 17 - 5 = 12
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
The math property for 12=17-5 then 17-5=12 would be the symmetric property of equality.
Tip: The symmetric property of equality states that no matter what side the equations and answer are it will still be equal, but it only works for the equal sign.
The math property for 12=17-5 then 17-5=12 would be the symmetric property of equality.
What is Number system?A number system is defined as a system of writing to express numbers.
Given that 12 = 17 - 5, then 17 - 5 = 12
we need to check which property will be used.
The math property for 12=17-5 then 17-5=12 would be the symmetric property of equality.
The symmetric property of equality is really quite simple. This property states that if a = b, then b = a. That is, we can interchange the sides of an equation, and the equation is still a true statement.
Hence, the math property for 12=17-5 then 17-5=12 would be the symmetric property of equality.

What is the value of x in the equation 2x + 3y = 36, when y = 6?
8
9
027
36
Answer:
x = 9.
Step-by-step explanation:
The first step I did was replace y with 6.
[tex]2x+3\cdot \:6=36[/tex]
I multiplied 3*6 next.
[tex]2x+18=36[/tex]
Then I subtracted 18 from both sides of the equation.
[tex]2x+18-18=36-18[/tex]
After, I simplified the equation.
2x=18
Divided the both by 2 and then simplified again to get...
[tex]\frac{2x}{2}=\frac{18}{2}[/tex]
[tex]x=9[/tex]
So [tex]x=9[/tex].

Find KJR
Options: 4
61
55
50
Answer:
61
Step-by-step explanation:
Let's see what to do buddy...
_________________________________
KJI = KJR + RJI
So :
172° = ( 6x -5 )° + ( 12x -3 )°
172° = 18x - 8°
Subtract the sides of the equation plus 8°
180° = 18x
Divided the sides of the equation by 18
x = 180/18
x = 10°
_________________________________
So we have :
KJR = 6x -5 = 6(10) - 5 = 60 - 5 = 55°
KJR = 55°
_________________________________
And we're done.
Thanks for watching buddy good luck.

A line passes through the points (−8,−7) and (−4,−4). What is the equation of the line in Slope-Intercept Form? (A y=43x−1) (B y=34x−1) (C y=43x+1) (D y=34x+1)
Answer:
y=43x−1
Step-by-step explanation:
The equation of the line in Slope-Intercept Form is B: y = (3/4)x − 1.
What is the meaning of Slope-Intercept Form?The slope intercept form of such a straight line is among the most common ways to represent a line's equation. When given the slope of a straight line and the y-intercept, the slope intercept equation can be utilized to find the equation of a line.For the given question.
The line passes through the points-
(x1, y1) = (−8,−7)
(x2, y2) = (−4,−4).
Find the slope using formula;
slope = m = (y2 - y1)/(x2 - x1)
m = (-4 + 7)/(-4 + 8)
m = 3/4
The equation of the line in slope intercept form is found by;
y - y1 = m(x - x1)
y + 7 = (3/4)(x + 8)
y = (3/4)x - 1
Thus, the equation of the line in Slope-Intercept Form is B: y = (3/4)x − 1.

Find the measure of this missing angle?
Answer:
B = 61°
C = 61°
Step-by-step explanation:
The sum of all the angles is 360.
When the angles are formed with straight lines like shown the angles back to back are equivalent or equal.
So you can take 119 and add it by itself to get 238.
You then get 360 and subtract 238 which gets you 122.
Then divide 122 by two and you have the answer for both b and c which is 61.

Answer:
Yes because the lines never intersect.
Answer
No
Step-by-step explanation:
If a and b were parallel, then
∠ 3 and ∠ 5 would be alternate angles and congruent.
However, ∠ 3 = 96° and ∠ 5 = 84°, that is not congruent
Thus a and b are not parallel

In the diagram below, all measurements are given correct to the nearest cm. Calculate the greatest possible area of the shaded region.
The possible area of the region that is shaded is given as 462cm.
How to solve for the area of the shaded regionThe picture here shows us two rectangles.
The area of a rectangle is given as L * w
= length x width
We have to find the area of the first rectangle
21cm x 42cm
= 882 cm
Next we find the area of the rectangle inside
15cm x 28cm
= 420
To get the area of the shaded region
