Answer:
A,C,D i believe
Step-by-step explanation:
Okay. Let's make a proportion for this. So we can do 21/3=x/60. Let's multiply cross way. So 21 x 60 is 1260. We multiply 3 by x to get 3x. So our equation will be 3x=1260. We can isolate the equation by 3, and 1260 divided by 3 is 420. So x=420. We then have to convert into feet. So 420 divided by 12 is 35. So it would be 35 feet. Therefore, the machine can make 35feet of ribbon in a hour.
Answer:
each number in the ratio 4:5:7 is worth 6 sweets. add 4,5, and 7 to get 16 then multiply it by 6 to get 96 sweets.
Step-by-step explanation:
add the ratios = 4+5+7= 16
1 number = 6 so
4x6= 24
5x6=30
7x6=42
Frank gets 24 sweets
Mary gets 30 sweets
Seth gets 42 sweets
The total number of sweets they shared is 24+30+42= 96
The share 96 sweets altogether.
The check your answer; do 42-24= 18
Therefore, now we know that the difference between Seth and Frank's amount of sweets is 18.
Therefore, this is correct.
Answer:
is 28 because is probablity
Step-by-step explanation:
yes
It's -18.
-1/6b=3
Multiply the reciprocal of -1/6 to both sides, this will get x by itself
(-6/1)*-1/6b=3*(-6/1)
b= -18/1
b= -18
