7.D is the correct answer. I simplified 12/27 to 4/9 then i try to see if 4/9 is equivalent to 20/45 and it is you multiply 4 and 9 by 5= 20/45

8. 1.4*2.1=2.94 then 2.94/1.5= 1.96 so c=1.96

9. Explanation You multiply- 5/8 * 3/5 then divide = answer divided by 2/3

Solving: 5/8*3/5= 3/8 then 3/8 divided by  2/3, flip second number and then switch the division sign to multiplication sign so it should be like this : 3/8 * 3/2= 9/16
answer= 9/16

Solve for k. Describe the steps taken to find the solution.<br> 8 + 10 - 6k = 6(4 - k)
BartSMP [9]

Answer:

no solutions

Step-by-step explanation:

8 + 10 - 6k = 6(4 - k)

Distribute

8 + 10 - 6k = 24 -6k

Combine like terms

18 -6k = 24 -6k

Add 6k  to each side

18 - 6k +6k = 24 - 6k+6k

18 = 24

This is never true so there are no solutions

kondor19780726 [428]

Answer:

54°

Step-by-step explanation:

Your triangle is isosceles. You have been given the third angle, and you have been asked to find the measure of one of the two equal angles. We know that the internal angles of a triangle sum to 180, so 72+x+x=180 \rightarrow 2x=108 \rightarrow x = 54
