Find the measure of KM¯¯¯¯¯¯¯¯¯¯.

PilotLPTM [1.2K]

Answer:

Step-by-step explanation:

(whole secant) x (external part) = (whole secant) x (external part)

( 7+x+2) * 7 = ( 6+8) * 6

Combine like terms

(9+x) *7 = 14*6

Distribute

63 +7x = 84

Subtract 63

63 +7x -63 = 84-63

7x =21

Divide by 7

7x/7 = 21/7

x = 3

KM = x+2+7

= 3+2+7

=12

Mary used Delicious (d) and Golden Delicious (g) apples to make homemade applesauce. Delicious apples are $0.75 each and Golden

alina1380 [7]

Answer:

Mary bought 9 Golden Delicious apples

Step-by-step explanation:

This can be solved by setting up a system of equations. Based on the information given, the equations would be set up as follows.

$.75d+1.25g=21.00\\d+g=22$

I prefer to solve using substitution, but elimination can be used as well

$.75d+1.25g=21.00\\g=22-d$

We can now plug in this g value to the first equation

$.75d + 1.25 (22-d)=21.00\\.75d + 27.5-1.25d=21\\27.5-0.5d=21\\-.5d=-6.5\\d=13$

This means mary bought 13 delicious apples. She bought 22 apples in total, so the total number minus the amount of delicious apples will give us the amount of golden delicious apples.

22 - 13 = g

9 = g

I need help with rhombus,rectangles and squares<br>

AnnZ [28]

Answer:

a= 11, b= 12

Opposite angles of parallelogram are equal.

m<D = m<B

9b-2=106°

9b= 108°

b= 12°

Sum of the adjacent angles of a parallelogram = 180°

m<B+m<C = 180°

106°+7a-3=180°

7a = 180°-106°+3

7a=77°

a= 11°

In a parallelogram, two sides are each length 12, and the perimeter is 36, what is the length of the remaining sides?

tankabanditka [31]

P=2a+2b
P=36
a=12
36=2*12+2b
36=24+2b
36-24=2b
12=2b
b=6
So, the length of the remaining sides is 6 each.
