You'll need to use parentheses here to convey this problem accurately to possible helpers.  Unsure of whether you mean (9/2)k -3 or  9 / (2k-3).

I will assume that you mean:

    9           4
------- = ---------
2k-3        k+1

Cross mult:  9k+9=8k-12, so k= -21.

If that's not what you expected, then try again to present the problem without ambiguities.

In ABC, the measure of sides c is 3.9 cm If DEF is a dilation ABC with a scale factor of 2.5 what is the measure of side f
White raven [17]

Answer:

F = 9.75cm

Step-by-step explanation:

Given

In ABC;

C = 3.9cm

Dilation = 2.5

Required

Determine side F

In the given question;

DEF is a dilation of ABC

Comparing both triangles side by side,

Side F is a direct dilation of side C and this is calculated as follows

F = Dilation * C

F = 2.5 * 3.9cm

PLEASE HELP ME!
arlik [135]

Answer:

Angle: 22.5 deg, Complement: 67.5 deg, Supplement: 157.5 deg

Step-by-step explanation:

22.5 is 1/3 of 67.5

so compliment is 67.5.

Supplement is just adding another angle so I chose 7.

I did 22.5 x 7 = 157.5

Another example would be:

Angle: 10 deg, Complement: 30 (because 10 x 3), Supplement: 70 (because 10 x 7)

Hope this helps :)

Solve the following equation. Please round answer to the nearest tenth. <br> 4x+4= -0.3x+3
sesenic [268]

Answer:

x = - 0.2

Step-by-step explanation:

4x+4= -0.3x+3

4x + 0.3x +4= 3     Add 0.3x to both sides

4.3x + 4 = 3      Simplify

4.3x  = 3 - 4    Subtract 4 from both sides

4.3x  =  -1    Simplify

4.3x  =  -1    Divide by 4.3 to isolate the variable

x = - 0.2
