<u>Answer:</u>
The correct answer option is D. 
.
<u>Step-by-step explanation:</u>
We are given the following expression and we are to simplify it:
Here the variables 
and 
are having negative powers. So to change these powers from negative to positive, we will take their reciprocals to get:
Answer:
42
Step-by-step explanation:
9 × 6 = 54
So 7 × 6 = 42 successful throws
Stander form: 4x-y=-2
A:4
B:1
C:-2
None of them because they are all 4 blank
Answer:
7/3 or 13/15
Step-by-step explanation:
So you told me that it will be
8/(20/9) -2 11/15 I put parenthesis to make it easier to understand for me
so you must know that a/(b/c)=ac/b si
72/20 -2 11/15 so we work with -2 11/15 which is equal to -30/15 + 11/15 and that will be -19/15 so we have
72/20 - 19/15 we simplify
18/5 - 19/15 so we multiply and divide by 3 in 18/5
54/15 - 19/15 and we add up
35/15 which is equal to
7/3
If this is wrong <u>so we work with -2 11/15 which is equal to -30/15 + 11/15 </u> well it should be so we work with -2 11/15 which is equal to -30/15 - 11/15 and that equals -41/15 and we get
54/15-41/15
13/15
