Solve for x. 3x/4+2x/3=51
a)122.4
b)36
c)3
pick a, b, or c

B

Step-by-step explanation:

Given

+ = 51

Eliminate the fractions by multiplying through by the lowest common multiple of the denominators 4 and 3

The lowest common multiple of 3 and 4 is 12

12 × + 12 × = 12 × 51

9x + 8x = 612

17x = 612 ( divide both sides by 17 )

x = 36 → B

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
