28.50x + 110.99(14-x)=811.45

distribute

28.50 x + 1553.86-110.99x =811.45

combine like terms

-82.49x+1553.86=811.45

subtract 1553.86 from each side

-82.49x =-742.41

divide by -82.49

x=9

He bought 9 of the 28.50 features and 5 of the 110.99 features

if f(1) = -5 and f(n) = f(n-1) +7, find the first four terms and the common difference of the sequence
Alex_Xolod [135]

Answer:

- 5, 2, 9, 16 and d = + 7

Step-by-step explanation:

to obtain the first four terms substitute n = 2, 3, 4 into the recursive formula

f(1) = - 5 ← given

f(2) = f(1) + 7 = - 5 + 7 = 2

f(3) = f(2) + 7 = 2 + 7 = 9

f(4) = f(3) + 7 = 9 + 7 = 16

common difference d = 16 - 9 = 9 - 2 = 2 - (- 5) = 7

Trying to find the right answer to an improper fraction as a mixed number 4 / 3.
svetlana [45]
1 1/3 is the answer 

you have to subtract the numerator of the improper fraction  from the denominator and the number you have left is the fraction like for 4/3    4-3=1 so the fraction is 1/3 the amount that is NOT a fraction counts as the whole depending on how many times it can go into the denominator.
