Answer:
50 score/71.43%
Step-by-step explanation:
25/35
You need to multiply both the numerator and denominator by 2 due to the fact 70 divided by 35 equals to 2.
50/70 if you divide 50 by 70, you get 71.428- which is rounded to 71.43
1/7 and 3/14......common denominator is 14
2/14 = 3/14
cross multiply
(14)(3) = (14)(2)
42 = 28...not correct...no, this does not form a proportion
little tip ** proportions are nothing but equivalent fractions and 1/7 does not equal 3/14...now if it would have been 1/7 and 2/14...then it would have been a proportion
Answer:
Frederick is not correct.
Step-by-step explanation:
30% of $80 is $24, not $2.40. The math can be done by taking 80 and multiplying it by .3 (which is 30% in decimal form). This gives you $24.
Answer:
x = 33/3 = 11
Step-by-step explanation:
A and B are corresponding angles and are therefore equal.
Thus, A = 8x - 8 = B = 5x + 25, or
3x = 33
and so x = 33/3 = 11
