You are asked to find the missing value in

... 40 + ? = 70

given that it is also the solution to

... ? + 5 = 35

Either way, you subtract the constant that is on the same side of the equation as the unknown.

... 40 + ? - 40 = 70 - 40

... ? = 30 . . . . the missing value

_____

You can check to see if this also satisfies the equation

... 30 + 5 = 35 . . . . . . . true

Arrange the numbers in order from smallest to largest:
12, 18 , 25, 26 , 30, 31 , 34

Find the highest and lowest numbers, those would be where the black dots go on the number line.

Lowest number = 12
 Highest number = 34

The line inside the box would be the Median number of the set.
Find the median (  middle value):
 Since there is an odd amount of numbers the median would be the middle number:
 Middle number = 26
 

The graph that has the black dots on 12 and 34 and the line of 26 is the first one

X=-2y-3 4y-x=9 determine the point of intersection of each pair of lines if one exists. ​
Drupady [299]

Answer: (-5,1)

Step-by-step explanation:

x=-2y-3

4y-x=9

4y-(-2y-3)=9

4y+2y+3=9

6y+3=9

6y=6

y=1

x=-2y-3

x=-2-3

x=-5

Instructions: Find the value of 2.
frosja888 [35]

Answer:

x = 50°

2x = 100°

Step-by-step explanation:

Chords AB and DC are equidistant (3 units) from the center E of the circle.

Since, the chords equidistant from the center of the circle are congruent.

Congruent chords intercepts congruent arcs.

Hence, x = 50°

2x = 2*50° = 100°

Answer:

Step-by-step explanation:

3x + 5y = 7

Since that is our original form, let's convert it so that we can find the slope:

5y = -3x + 7

y = -3/5 x + y

 

To get a perpendicular line, we need the negative reciprocal of the slope. This means that the sign switches and numerator and denominator flip:

m = 5/3

 

From here, we use the point-slope equation and then convert that into slope-intercept form:

y - y1 = m(x - x1)

y - 6 = 5/3(x - 0)

y - 6 = 5/3x
