Answer:

x=8

Step-by-step explanation:

In other words, you are looking for a number (x) that if you multiply it by two (same as twice) and then add 7, you get 23.

To solve this, you first write the problem as an algebra equation as follows: 2x + 7 = 23

Then you solve the equation by subtracting 7 from both sides, and then divide both sides by 2. Here is the math to illustrate better:

2x + 7 = 23

2x + 7 - 7 = 23 - 7

2x = 16

2x/2 = 16/2

x = 8

AD = DB

Angle ADE = Angle CDB

Angle DAE = Angle DBC (Alternate angles)

Angle DEA = Angle DCB (Alternate angles)

Since you have two congruent angles and one congruent side, triangle ADE is congruent to triangle CDB. This means that DE is congruent to DC implying D is the midpoint of CE.

What can you conclude about these triangles? Check all that apply.
AfilCa [17]

Comparing the angles:

G = K = 58

F = J = 87

So E = L = 35

All the angles are the same for both, so they are congruent, not proportional.

Because the side lengths are different on the two triangles they cannot be congruent ( exactly the same) but they are similar since the 3 inside angles are the same.

The answers are:

Angle E corresponds to angle L.

The two triangles are similar.

What is the solution for -10 < x - 9?
storchak [24]

Answer:

x > -1

Step-by-step explanation:

-10 < x - 9 add 9 to both sides of the inequation

9 + (-10) < x - 9 + 9 minus 9 will eliminate the positive 9 on the right side of the inequation therefore the answer is:

-1 < x  and x > -1

Interesting Question
What you are being asked is What is the line Perpendicular to AB going through point (7,6)

Step One
What is the slope of the given line
-7x + 3y = -21.5     Add 7x to both sides.
3y = 7x - 21.5        Divide by 3
y = 7x/3 - 21.5/3

The slope of the given line is 7/3 (just read it)

Step Two
What is the slope of the line perpendicular to it.

The slopes are connect by the formula
m1 * m2 = - 1
m1 = 7/3
7/3 * m2 = - 1 Multiply by 3/7
m2 = - 1 * 3/7
m2 = - 3/7

Step three
Find the y intercept, where b in the equation below is the y intercept..
y = -3/7 x + b
y = 6
x = 7
6 = -3/7 * 7 + b
6 = -3 + b    Add 3 to both sides.
6 + 3 = b 
b = 9

Step Three
State the equation
y = - 3/7 x + 9

Now you have to juggle the numbers to get the answer. 

Step 4
put the -3/7 x on the left side.
y + 3/7 x = 9     Multiply both sides by 7
7y + 3x = 63     Now for some strange reason, you divide by 2
3.5y + 1.5x = 31.5  The answer is the second one down (middle one).
