Answer:
132
Step-by-step explanation:
[tex]\frac{x}{12}+3=14[/tex]
Subtract 3 (from both sides of the equation, of course).
[tex]\frac{x}{12}=11[/tex]
To "undo" the division, multiply by 12.
[tex]12\cdot\frac{x}{12}=11(12)\\x=132[/tex]
ABCD is a rhombus. The diagonals intersect at point E. If angle CDB= 6x and angle ACD= 2x+10, find x.
Answer:
x = [tex]10^{o}[/tex]
Step-by-step explanation:
The diagonals of a rhombus are perpendicular to each other, thus the angle at point E is [tex]90^{o}[/tex]. So that ΔCED is a right triangle, and that;
<CDB = <CDE
<ACD = <ECD
<CDE + <ACD + <CED = [tex]180^{o}[/tex] (sum of angles in a triangle)
6x + (2x + 10) + [tex]90^{o}[/tex] = [tex]180^{o}[/tex]
8x + 100 = [tex]180^{o}[/tex]
8x = [tex]180^{o}[/tex] - 100
8x = 80
x = [tex]\frac{80}{8}[/tex]
= [tex]10^{o}[/tex]
Thus, the value of x is [tex]10^{o}[/tex].

have a good day :)
Step-by-step explanation:
Answer:
D. 50
Step-by-step explanation:
∠CGF and ∠AFG add up 180° because they are same side interior angles. We can write an equation to model the situation:
m∠CGF + m∠AFG = 180°
And, we can substitute:
3x - 20 + x = 180
4x - 20 = 180
4x = 200
x = 50

Dominic has a bag that contains pineapple chews, cherry chews, and peach chews. He performs an experiment. Dominic randomly removes a chew from the bag, records the result, and returns the chew to the bag. Dominic performs the experiment 53 times. The results are shown below:
A pineapple chew was selected 39 times.
A cherry chew was selected 9 times.
A peach chew was selected 5 times.
Based on these results, express the probability that the next chew Dominic removes from the bag will be peach chew as a fraction in simplest form.

The measure of L in triangle LMN is 36°. The measure of M is 75°. What is the measure of N? PLEASE HELP
A.
111°
B.
39°
C.
69°
D.
249°
Answer:
C. m∠N = 69°
Step-by-step explanation:
The sum of the measures of the angles of a triangle is 180.
m∠L + m∠M + m∠N = 180
36 + 75 + m∠N = 180
111 + m∠N = 180
m∠N = 69°

The length of an equilateral triangle is increased by 5 cm. The perimeter of the new triangle is 72 cm. What is the side length of the original triangle?
Answer:
19cm
Step-by-step explanation:
An equilateral triangle is a triangle where the length of the 3 sides are the same.
the perimeter is the sum of the 3 sides
for example, if the length of the side of the an equilateral triangle is 5, the perimeter is 5 x 3 = 15
let x = unknown length of side
length after increase = x + 5
(x + 5) x 3 = 72
divide both sides of the equation by 3
x + 5 = 24
subtract 5 from both sides of the equation
x = 24 - 5 = 19cm
what is the correct solution? from the graph ( x , y )
What is the measure of ∠A, the exterior angle of the triangle shown below?
Answer:
88
Step-by-step explanation:
Each triangle has a sum of 180 degrees. So we find the missing angle with this rule.
180-38-50.
The angle is 92 degrees.
Now to find the angle of A, each angle adds up to 180 on a line. so 180-92. So you get 88
Answer:
Step-by-step explanation:
38+50=angle A(the sum of two interior opposite angle is equal to the external angle formed)
88=angle A

Solve all the questions
Answer:
1. x= 9
2. x= −2
3. 51 inches
4. $213.11 each month
Step-by-step explanation:
1. Simplify both sides of the equation.
x + 7 + 7x= 25 + 6x
Combine Like Terms
(x + 7x) + (7)=6x + 25
8x + 7= 6x + 25
8x + 7= 6x + 25
Subtract 6x from both sides.
8x + 7 − 6x= 6x + 25 − 6x
2x + 7= 25
Subtract 7 from both sides.
2x + 7 − 7= 25 − 7
2x= 18
Divide both sides by 2.
2x/2= 18/2
2. Subtract 5x from both sides.
x − 5x= 5x + 8 − 5x
−4x= 8
Divide both sides by -4.
−4x/−4= 8/−4
3. First find the perimeter of the trapezoid
4 + 3 + 4 + 8= 19
A square has all equal sides
8 * 4= 32
Add them together
19 + 32 = 51 inches

Leila is at a charity fundraiser and has a chance of receiving a gift 6/17 . The odds in favor of receiving a gift are . Find the probability of Leila receiving a gift.
Answer:
6 / 23
Step-by-step explanation:
The question is not correct, the correct question is:
Leila is at a charity fundraiser and has a chance of receiving a gift. The odds in favor of receiving a gift are 6:17. Find the probability of Leila receiving a gift.
Solution:
Odds provide a measure of the likelihood of a particular outcome occurring. Odds is the ratio of the number of events that produce that outcome to the number that do not.
The probability of an event occurring is the ratio of number of favorable outcomes to the total number of outcomes possible.
Given that the odds in favor of receiving a gift are 6:17. Therefore:
number of favorable outcome = 6, number of unfavorable outcome = 17
Total number of possible outcomes = 6 + 17 = 23
The probability of Leila receiving a gift = number of favorable outcome / Total number of possible outcomes = 6 / 23
The probability of Leila receiving a gift = 6 / 23
