Answer:
x = 3/2
Step-by-step explanation:
7/3 = (x + 2)/x
7x = 3(x + 2)
7x = 3x + 6
4x = 6
x = 6/4 = 3/2

Step-by-step explanation:
1 Subtract 66 from both sides.
2x=10-6
2x=10−6

We move all terms to the left:
2x+22-(18)=0
We add all the numbers together, and all the variables
2x+4=0
We move all terms containing x to the left, all other terms to the right

Answer:
A = 65deg
B = 78deg
Step-by-step explanation:
It's a triangle, so we know that the sum of angles is 180deg
x + (2x - 9) + (2x + 4) = 180
5x - 5 = 180
5x = 185
x = 37
Measure of angle A = (2*37 - 9)deg = 65deg
Measure of angle B = (2*37 + 4)deg = 78deg
Round to the nearest 10th

find the geometric mean between 12 and 20 find the answer in radical form
Answer:
4√15
Step-by-step explanation:
The geometric mean of x and y is √(xy).
So here we have:
√(12*20)
= √240
= √(16*15)
= √16√15
= 4√15.

Step-by-step explanation:
1. Rewrite the equation 5(x - 3) = x + 13 with 6 substituted for x. Write a
question mark over the equal sign to show that you're testing to see if the
equation is true
2. Simplify both sides. Show your work.
3. Is x = 6 a solution to the equation? Why or why not?
4. Find a value of x that is a solution to 5(x - 3) = x + 13. Describe how you
found the solution
Answer:
Step-by-step explanation:
5(6-3)=6+13 -simplify
30-15=6+13
15=19
x doesnt equal 6
5(x-3)=x+13
5x-15=x+13
4x=28
x=7
4x=28
4(7)=28
28=28
Camile shaded 18/30 of a model write the decimal that represents the unshaded portion of the model
Answer:

Camile shaded 18/30 of a model.
Thus the unshaded portion of the model is:
30 - 18 = 12
12/30
12/30 = 0.4

Solve the area of a trapezoid formula for the variable h: A = 1/2h(b1 + b2)
Note: In this formula, A = area, H = height, and b1 and b2 are the bases of the trapezoid.
The area of the trapezoid formula can be solved for the variable h as,
h = 2A / (b1 + b2)
Given the formula to find the area of the trapezoid.
A = 1/2 (b1 + b2) h
Here A is the area, h is the height and b1 and b2 are the bases of the trapezoid.
We have to get an equation for formula in h.
That is, we need to isolate h alone on one side and the other terms and variables on other side.
Multiplying whole equation with 2,
2A = (b1 + b2) h
Dividing whole by (b1 + b2),
h = 2A / (b1 + b2)
Hence the required equation is h = 2A / (b1 + b2).

Based only on the information given in the diagram, which congruence
theorems or postulates could be given as reasons why ADEF= AKLM?
Check all that apply.
AA
O A. LA
ОВ. НА
O C. AAS
D. SAS
E HL
F.LL
=================================================
Explanation:
LA stands for Leg Angle. More specifically, the angle is an acute angle. This theorem only works for right triangles. We see that ED = LK which is one pair of congruent leg segments. So that takes care of the L part of LA. However, we don't know anything about the acute angles. We don't know if angle E = angle L, or if angle F = angle M, or something along those lines. We need angle markers to tell us or not.
In short, we only have half the info needed for LA, so we must cross choice A off the list.
----------------
HA stands for hypotenuse angle, or hypotenuse acute angle, and this rule only applies for right triangles. We don't know anything about the hypotenuse lengths if they are the same or not.
Similar to choice A, we don't know anything about the acute angles either.
Those two facts mean we must cross off choice B.
----------------
AAS stands for Angle Angle Side. The order is important because the side is not between the angles. The diagram only shows one pair of angles that are congruent to one another. That pair being the 90 degree angles indicated with the square marker. We don't have another pair of angles, so we cannot use AAS.
Cross choice C off the list.
-----------------
We can use SAS because we have two pairs of congruent sides and one pair of congruent angles.
The congruent sides are
ED = LK (double tickmarks)DF = KM (single tickmarks)That takes care of the two "S"s of "SAS". The "A" would be those two right angles which are congruent to one another. The angles are between the congruent sides which is important. Recall that SSA is not a valid congruence theorem.
So that's why choice D is the only answer.
-----------------
Side note: We could use the LL theorem, where L stands for leg, since we are given two pairs of congruent legs for each triangle. Like LA and HA, this only applies to right triangles. LL is a special case of SAS. However, LL isn't listed so we'll just be sticking with SAS as the only answer.
