(9x + 5)
(12x - 19)
Answer: x=8 angle BDC=77
Step-by-step explanation:
9x-12x=-19-5
-3x=-24
x=8
12x(8)-19
=77
(9x + 5) and (12x - 19) are one angle split equally.
(9x + 5) = (12x - 19)
The value of m∠BDC is 65°
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles are equal to 180 degrees.
We have,
(9x + 5) and (12x - 19) are one angle split equally.
So,
9x + 5 = 12x - 19
We will solve for x.
9x + 5 = 12x - 19
Add 19 on both sides.
9x + 5 + 19 = 12x
Subtract 9x on both sides.
24 = 12x - 9x
24 = 3x
Divide both sides by 3.
24/3 = x
x = 7
Now,
The value of m∠BDC.
= 12x - 19
= 12 x 7 - 19
= 84 - 19
= 65°
Thus,
The value of m∠BDC is 65°

-9 + p/2= -13
(two step equations, show your work)
Answer:
p=−8
Step-by-step explanation:
Regroup terms.
p /2 −9=−13
Add 9 to both sides.
p/2 =−13+9
Simplify -13+9 to −4.
p/2=−4
Multiply both sides by 2.
p=−4×2
Simplify 4×2 to 8
p=−8.

Suppose cos(x)=-1/3, where pi/2≤x≤ pi. What is the value of tan(2x)?
Answer:
4√2/7
Step-by-step explanation:
Suppose cos(x)=-1/3, where pi/2≤x≤ pi
tan(2x) = sin(2x)/cos(2x)
Since sin2x = 2sinx cosx
cos 2x = 2cos²x-1
Substitute
tan(2x) = 2sinx cosx/ 2cos²x-1
Given cosx = -1/3
adjacent = -1
hyp = 3
opp = √3²-(-1)²
opp = √9-1
opp = √8
sinx = opp/hyp
sinx = √8/3
tan(2x) = 2sinx cosx/ 2cos²x-1
tan(2x) = 2(√8/3)(-1/3)/ 2(-1/3)²-1
tan2x= (-2√8/9 )÷ (2/9 - 1)
tan2x = -4√2/9 * 9/-7
tan 2x = 4√2/7

What is AE?
Enter your answer in the box.
Answer:
(2x+6)/10 = (x+6)/8
10(x+6) = 8(2x+6)
10x + 60 = 16x + 48

x = 2
so
AE = 2(2) +6
AE = 4 + 6
AE = 10

Answer:
70 degrees
Step-by-step explanation:
The exterior angle in a triangle is equal to the sum of the two opposite interior angles
So,
the two interior angles in the question are U and T while the exterior angle is V.
Using this,
U+T =V
U+50 = 120
(make U the subject of formula)
U = 120 - 50
U = 70 degrees

Two numbers are in the ratio 4: 5
One of the numbers is 60
There are two possible values for the other number.
What are the two possible values?
Answer:
48 and 75
Step-by-step explanation:
Given data
We are given that the ratio is 4:5
we have two numbers, the bigger and the smaller number
case one: bigger= 60
the smaller is
4/5= x/60
5x= 60*4
5x= 240
x= 48
case two: smaller number = 60
4/5=60/x
4x= 60*5
4x= 300
x= 300/4
x= 75
Hence the two possible numbers are 48 and 75

A cell phone provider offers a plan that costs $20 per month plus $0.20 per text message sent or received. A comparable plan costs
$30 per month but offers unlimited text messaging. Complete parts a. and b. below.
a. How many text messages would have to be sent or received in order for the plans to cost the same each month?
In order for the plans to cost the same.
text messages would have to be sent or received
b. If you send or receive an average of 200 text messages each month which plan would you choose and why?
Answer:
Step-by-step explanation:
a)
30=20+0.2m
10=0.2m
50=m
So after sending 20 messages the plans would cost the same.
b)
Obviously from the first part that the unlimited plan is cheaper when sending 200 messages, but the costs numerically would be.
Unlimited plan costs $30 while the other plan costs
20+0.2(200)=$60
