Step-by-step explanation:
0.75 yard = 1 costume
1 yard = 1/0.75 =4/3 costume
6 yards = 4/3 × 6 = 8 costumes
if you wanna check,
8 costumes = 6 yards
1 costume = 6/ 8
= 3/4 (0.75) yard
Answer:so the answer would be 11 dollars$ if she bought 9 tickets and a 5 dollar serice charge they would be 11$. put 11x9=99+5=104
Step-by-step explanation:
Answer:
A. This study is an experiment, since it was based on a random sample.
Step-by-step explanation:
Simple random sampling is a probabilistic sampling procedure that gives each element of the target population and each possible sample of a given size the same probability of being selected.
I agree with what that person told you. The expression -2(x+10) is equivalent to -2x-20
Multiply the outer -2 with the inner x to get -2 times x = -2x
Multiply the outer -2 with the inner term 10 to get -2 times 10 = -20
So overall, -2(x+10) = -2x-20

So that's how we're able to go from this

to this

The only thing that changes is the left side. The inequality sign will not flip. It only flips if we multiply both sides by a negative number.
