Ineed with all answers (i don’t get anything) : ’)

23. 2 ; 24. 1/10 ; 25. 3/2 ; 26.8 costumes ; 27. 3000 ft^2/hr ; 28. 3/125 ; 29. 31/400 ; 30.about 1/12 ; 31. see below

Step-by-step explanation:

Fractions in the form (a/b)/(c/d) can be also expressed as (a*d)/(b*c)

23.(1/2)/(1/4) = (1*4)/(2*1) = 4/2 =2

24.(1/12)/(5/6) = (1*6)/(12*5) = 6/60 = 1/10 or 0.1

25.(5/6)/(5/9) = (5*9)/(6*5) = 45/30 = 3/2 or 1.5

26. Divide the number of fabric she has to the number she needs to get in order to find out how many costumes Mrs. Frazier can make

6/0.75 or 6/(3/4) = (6*4)/(3*1) = 24/3 = 8 costumes

27. Same procedure, I recommend changing the mixed fraction to an improper

7500/(5/2) = (7500*2)/(5*1) = 15000/5 = 3000 ft^2/hr

28. 2 2/5% is 2.4% = 0.024 = 24/1000 = 3/125

29. 7 3/4% is 7.75% = 0.0775 = 775/10000 = 31/400

30. 8 1/3% is 8.33% = 0.0833333 = 8333/100000 = about 1/12 (use a calculator)

31. Convert into an improper fraction, then divided numerator by denominator to find the decimal counterpart. Convert percentage into decimal form and then into fraction form and simplify.

1 1/4 is 1.25% = 0.0125 = 125/10000 = 1/80

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

idk
