15.
4(x-2) = 2(x-4)+2x
i used the distributive property on the parantheses to then get...
4x-8 = 2x-8+2x
I combined the like terms to then get...
4x-8 = 4x-8
+8 +8
4x = 4x
which simplifies to....
x=x
so the answer to question 15 is x=x

17.
-4(p+1) = -2(8-2p)
I used the distributive property on the parantheses....
-4p-4 = -16+4p
+4 +4
-4p = -12+4p
-4p -4p
-8p = -12
÷-8 ÷-8
p = 1.5

so the answer to question 17 is p = 1.5

hope this helps!!!!

Find m angle TUV if m angle TUN=1+38 pi m angle NUV=66^ m angle TUV=105x
ipn [44]

Answer:

m∠TUV = 105

Step-by-step explanation:

From the question given above, the following data were obtained:

m∠TUN = 1 + 38x

m∠NUV = 66°

m∠TUV = 105x

m∠TUV =?

Next, we shall determine the value of x. This can be obtained as illustrated below:

m∠TUV = m∠TUN + m∠NUV

105x = (1 + 38x) + 66

105x = 1 + 38x + 66

Collect like terms

105x – 38x = 1 + 66

67x = 67

Divide both side by 67

x = 67 / 67

x = 1

Finally, we shall determine the value of m∠TUV. This can be obtained as shown below:

m∠TUV = 105x

x = 1

m∠TUV = 105(1)

m∠TUV = 105

2.) dT/dt = -t^2 + 3t

dT = (-t^2 + 3t)dt

T = -t^3/3 + 3t^2/2 + C

at 4:00 AM

80 = -4^3/3 + 3*4^2/2 + C

C = 80 + 4^3/3 - 3*4^2/2

C = 77.33

T = -t^3/3 + 3t^2/2 + 77.33

at 8:00 AM

T = -8^3/3 + 3*8^2/2 + 77.33

T = 2.67 deg

Polygon ABCDEF has 6 sides. A is 170° C is 133° D is 102° he is 117° and F is 90°. What is the measure of b?
Zielflug [23.3K]

Answer:

B = 134^o

Step-by-step explanation:

n = 6 --- sides

A = 170^o

C = 107^o

D = 102^o

E = 117^o

F = 90^o

Required

The measure of B

The interior angles of a polygon is:

Angles = (n - 2) * 180

So, we have:

Angles = (6 - 2) * 180

Angles = 4 * 180

Angles = 720^o

The measure of B is calculated using:

A + B + C + D + E + F = 720

Substitute known values

107 + B + 170 + 102 + 117 + 90 = 720

Collect like terms

B + 107 + 170 + 102 + 117 + 90 = 720

B + 586 = 720

Collect like terms

B = 720 - 586

B = 134^o

A boutique prices merchandise by adding 80%. It later decreases by 25% the price of items that do not sell quickly. Does the ord
k0ka [10]
The order you apply the adjustments does make a difference because the percents that are applied will be applied to different amount.  

For example, 80% of 100 = $80.  The price would be $180.

Decreasing this by 25% 25% of 180 = $45; 180-45 = $135.  

25% of 100 is not the same as 25% of 180.
