Can someone plz check to see if im correct or wrong and help me fix my answers?
for #1 i got x=15
#2 x=21
#3 x=20.83 repeating
#4 x=2.5
#5 x=10.66 repeating
#6 x=36
#7 x=14
#8 x=31.25

Step-by-step explanation:

1. long side : short side = 30 : 25 = 6 : 5 = 18 : 15

__

2. long square edge : shorter square edge = 28 : 24 = 7 : 6 = 21 : 18

__

3. long edge : short edge = 36 : 30 = 6 : 5 = 30 : 25

__

4. short parallel : slant edge = 20 : 12 = 5 : 3

__

5. long : short = 16 : 12 = 4 : 3 = 8 : 6

__

6. kite short edge : long edge = 20 : 30 = 2 : 3 = 24 : 36

__

7. short : long = 4 : 7 = 8 : 14

__

8. end : square edge = 20 : 35 = 4 : 7 = 16 : 28

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

step-by-step explanation:

you have to round up to 4 because 6 is over 5 so you have to round the 3 up to 4
